Mecpow X3 Pro: Unveiling its High-Precision Engraving Magic

Whether you’re a hobbyist, a business owner, or a DIY enthusiast, a laser engraver becomes a convenient tool if you are into creating custom designs. It allows you to develop custom-engraved products using various materials, such as wood, acrylic, leather, fabric, and even certain types of metal. But with so many models in the market, sometimes it becomes tough to figure out which is the best for you, so we want to introduce you to Mecpow X3 Pro, a module laser engraver with an extendable engraving area.

Yes! You read that right; this engraver has an extendable engraving aria, the standard dimension of 400mm x 410mm, but with some modification, it can extend up to 400mm x 750mm. That is a massive boost for your projects. It also has an air assist and pump, precision stepper motors, a large extendable engraving area, and user-friendly software support. All these features make the Mecpow X3 Pro an extraordinary tool for your engraving projects while offering remarkable value for its price.

The Laser Diode

The Mecpow X3 Pro has a powerful laser diode that can output up to 10W of laser power. The laser diode is a fixed-focus diode which means it’s reliable and almost maintenance-free. Additionally, it claimed to have a rectangular beam spot shape of 0.08mm x 0.06mm, which is impressive compared to other lasers in this category.

Fixed focus means no moving parts in the laser, unlike those which use mirrors and reflectors to divert the laser beam. That also means the beam width is narrower, and the engraver is almost maintenance-free.

It’s also shocking to see how small the laser head is compared to other laser engravers. Because of that, this engraver can reach an engraving speed of 100,000 mm/min, which is very high compared to others. But the most fascinating thing about this engraver is its engraving accuracy of 0.01mm. That is game-changing because a fast engraver tends to lag precision.

This laser cutter houses a powerful 10W laser that can cut various materials. For instance, it can cut 20mm pine wood, 15 mm black acrylic, and even 0.1 mm stainless steel in a single pass. It can do multiple passes to cut thicker materials and still produce a clean cut thanks to its revolutionary 0.01mm accurate laser beam.

The Focusing Procedure

One of the pain points of any laser engraver is its focusing process; that is why the developers of Mecpow came up with a unique workaround, and it’s done with the help of the included focusing plate.

To adjust the focus, you place the focusing screen on top of the object now move the laser head down until the laser head touches the focusing plate, and your focusing is done. That’s how easy it is to do the focus for this machine.

Special Features and Safety Measures

This laser engraver/cutter includes various special features, like Extendable Engraving Space, an Eye Protector shield, Air Assist, and more. It also includes safety features like Emergency Stop Button, Limit Switches, Fire Sensor, Alarm, and more.

Extendable Engraving Area

This engraver’s most interesting takeaway is its ability to expand its engraving area. The engraver has a standard engraving space of 400mm x 410mm, but with a kit, you can increase it to 750mm x 400mm.

It also features a built-in laser shield for better eye protection. The built-in laser shield filters out 98% UV light to protect your eyes. You will get a pair of laser safety glasses in the box for additional eye protection.

The Air Assist Pump

The Mecpow X3 Pro offers a fully controllable air assist pump that can be turned on and off automatically or controlled through Lightburn. The air assist pump increases cutting precision and quality by removing debris and smoke for a clear cut. It also blows out the additional combustible gasses, reducing the fire risk.

Other safety features include a Flame Sensor, an emergency stop button a gyroscope sensor to detect tilt. If the machine tilts more than 50±5°, the control board stops the machine to prevent damage. It also features a Security lock and bump protection for added security.

The limit switch feature is the best feature a laser engraver could have. With a limit switch, you can set a home command, and the printer head will go to the home position, just like a 3D printer would. It also helps a machine start from the same place every time, even after interruptions.

Software Support

The Mecpow X3 Pro is compatible with the free LaserGRBL software, though it can be somewhat laggy. I prefer LightBurn, which is well-organized and intuitive. However, LightBurn isn’t free. After a 1-month trial, there’s a $60 license fee. Despite the cost, it’s valuable because it significantly saves time.

With LaserGRBL, you can import vector files (NC, BMP, JPG, PNG, DXF…) and bitmap image files (BMP, jpg, png and gif), but with Lightburn, you have support for more formats like AI, SVG, DXF, PDF, HPGL, PLT, and RD for vector formats and PNG, JPEG, BMP, TIFF, TGA, and GIF for image formats.

For any laser engraver, a vector file is preferred because it guides the laser along the shape’s edges directly. This is faster than the dot-making method used for bitmap images.

You can find many free vector designs online and use programs like Inkscape or QCAD to create them. Additionally, you can download free vectors or purchase unique designs from sites like Etsy to enhance your work.

The laser engraver comes with various tools and accessories to get you started. You will get an air assist pump, user manual, adapter, controller, screws, screwdriver, Allen key, brackets, aluminum guide rods, and more in the box. All these components together provide a seamless engraving experience.

4 Channel Current Sense Amplifier – Low and High-Side Voltage Output

This 4-Channel current sense amplifier is designed for cost-optimized applications. This is a current-sense amplifier (also called a current-shunt monitor) that senses the voltage drop across current-sense resistors at common-mode voltages from –0.2 V to +26 V, independent of the supply voltage. The project was built using INA4180 chip which integrates a matched resistor gain network in four, fixed-gain 20V/V, this matched gain resistor network minimizes gain error and reduces the temperature drift. The board operates with a single 2.7-V to 5.5-V power supply. The four-channel INA4180 draws a maximum supply current of 900 µA. Resistors R2, R6, R8, R12, R3, R7, R9, R13 and Capacitor C3, C4, C5, C6 used as input filters. The gain of the amplifier is 20V/V, and external input resistors resulting a 0.9% gain error.

RSENSE and Device Gain Selection

The project is tested with 4 x 0.01Ω/3W current resistors, considering approx. current sense range up to 10A. The users may choose the appropriate current sense resistor and Amplifier with different gains as per requirement. Refer to the datasheet of the chip for more info. The accuracy of the INA4180 is maximized by choosing the current-sense resistor to be as large as possible. A large sense resistor maximizes the differential input signal for a given amount of current flow and reduces the error contribution of the offset voltage. However, there are practical limits as to how large the current-sense resistor can be in a given application. The INA4180 has a typical input bias current of 80 µA for each input when operated at a 12V common-mode voltage input. When large current-sense resistors are used, these bias currents cause increased offset error and reduced common-mode rejection. Therefore, using current-sense resistors larger than a few ohms is generally not recommended for applications that require current-monitoring accuracy. A second common restriction on the value of the current-sense resistor is the maximum allowable power dissipation that is budgeted for the resistor.

Overcurrent and Short Circuit Protection

The LMR38020 is protected from overcurrent conditions by cycle-by-cycle current limits on both the peak and valley of the inductor current. Hiccup mode is activated if a fault condition persists to prevent overheating. High-side MOSFET overcurrent protection is implemented by the nature of the peak current mode control. The high-side switch current is sensed when the high-side is turned on after a set blanking time. The high-side switch current is compared to the output of the error amplifier (EA) minus slope compensation every switching cycle.  The peak current of high-side switch is limited by a clamped maximum peak current threshold, I high side LIMIT, which is constant. The current going through the low-side MOSFET is also sensed and monitored. When the low-side switch turns on, the inductor current begins to ramp down. The low-side switch is turned OFF at the end of a switching cycle if its current is above the low-side current limit, ILS_LIMIT. The low-side switch is kept on so that the inductor current keeps ramping down until the inductor current ramps below the ILS_LIMIT. Then the low-side switch is turned OFF and the high-side switch is turned on after a dead time.

Thermal Shutdown

The LMR38020 provides an internal thermal shutdown to protect the device when the junction temperature exceeds 163°C. Both high-side and low-side FETs stop switching in thermal shutdown. Once the die temperature falls below 150°C, the device reinitiates the power-up sequence controlled by the internal soft-start circuitry.

Soft Start

The integrated soft-start circuit prevents input inrush current impacting the LMR38020 and the input power supply. Soft start is achieved by slowly ramping up the target regulation voltage when the device is first enabled or powered up. The typical soft-start time is 4.0 ms.

The LMR38020 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. The LMR38020 operates during input voltage dips as low as 4.2 V, at nearly 100% duty cycle if needed, making it an excellent choice for wide input industrial applications and MHEV/EV systems.

The LMR38020 uses precision enable to provide flexibility by enabling a direct connection to the wide input voltage or precise control over device start-up and shutdown. The power-good flag, with built-in filtering and delay, offers a true indication of system status, eliminating the need for an external supervisor. The device incorporates a pseudorandom spread spectrum for minimal EMI and the switching frequency can be configured between 200 kHz and 2.2 MHz to avoid noise-sensitive frequency bands. In addition, the frequency can be selected for improved efficiency at low operating frequency or smaller solution size at high operating frequency.

Senbiosys’ Jewelry-Like Smart Ring Aims to Make Health Monitoring More Discreet and Affordable

Senbiosys' Jewelry-Like Smart Ring Aims to Make Health Monitoring More Discreet and Affordable

Two former EPLF Ph.D. students have created Iris, a smart ring the size of a wedding band that can monitor health like a high-end smartwatch. Marketed by Senbiosys, they have already raised five times more than the initial target of 100,000 francs.

In this time and age, everyone has heard about smartwatches and fitness trackers; these wrist-worn devices can do everything from telling time to monitoring your heart rate and making phone calls. Smartwatches and fitness trackers have been around for a while, but what is recently creating buzz around the internet is a smart ring. Smart Rings are wearable accessories that you put around your fingers. But most of the time, they are bulky and uncomfortable to wear.

That is where Senbiosys comes in; in collaboration with EPFL, they have developed a PPG sensor that concentrates all the monitoring capabilities of smartwatches into an area four times smaller, breaking all records. This breakthrough in miniaturization enables the device to need much less power than a smartwatch while achieving the same result.

A PPG sensor uses a light source like an LED and a photodetector to measure vital signs like heart rate, blood oxygen levels, breathing rate and blood pressure, and more. The sensor does this by capturing the reflected light from the LED and feeding the information to an algorithm to calculate the vital signs. The YouTube video made by the founders explains the phenomenon a little better.

The PPG sensor developed by Senbiosys is just only four cubic millimeters in size, which is four times smaller than the ones found in smartwatches and fitness trackers. When developing micro semiconductors, miniaturization comes with the cost of power consumption. But extensive research at EPFL’s Integrated Circuits Laboratory in Neuchâtel has produced photodetectors that can pick up feeble signals just as clearly as a standard-sized sensor would do. This breakthrough in technology has made waves in the industry. Senbiosys co-founder says, “Our breakthrough has given rise to around 60 journal articles in microelectronics and optical sensors,”. He says, “It’s also led to 11 patents, including some obtained at EPFL, and our work has been cited around 1,000 times.”

There are a couple of reasons why Iris came into existence, the most important one being wearing a smartwatch during sleep is not only impractical but also uncomfortable. With Iris’s compact design and low power requirement, Iris looks like jewelry rather than a health tracker. The ring contains 18 LEDs, and six photodetectors, which enables the device to measure health parameters accurately.

Senbiosys conducted their research at the Fribourg cantonal hospital to compare heart data. The research was performed to determine the accuracy and reliability of the miniaturized sensors against traditional sensors. After this, Boukhayma, one of the co-founders, said, “Our aim is not to make a tool for doctors but to help individuals track their health.” At the initial release, Iris can measure heart rate, step count, blood oxygen level, sleep quality, stress level, and calories burned. But with improvement and advancement in the algorithm, they can daa in more features to this device.

The company has raised 5 million francs and used that to develop some prototypes. In 2022, they decided to make a product for regular people called Iris. With crowdfunding, they plan to ship out Iris orders by late 2023 after sorting out the making process.

UCC28180 – PFC Controller (Schematic and PCB Layout in Downloads below)

The UCC28180 module provides high performance and offers a series of benefits to address the next-generation requirement of low THD standards for appliances. The UCC28180 is a high-performance, compact continuous conduction mode (CCM), Frequency is programmed 120Khz using R11 and R15 The UCC28180 uses trimmed current loop circuits to achieve less than a 5% THD from a medium-to-full load (50% to 100%). A reduced current sense threshold enables the UCC28180 device to utilize a 50% smaller shunt resistor, resulting in lower power dissipation while maintaining low THD. The UCC28180 also consists of an integrated fast gate driver, with a drive of +2-A source current and −1.5-A sink current, which eliminates the requirement for an external gate driver.

Two Channel High Side Driver with Analog Sense for Automotive Applications

The project presented here is suitable for all types of resistive, inductive, and capacitive loads, and can also be used to drive LEDs. The board is built using 2 x VN5025AJ chips which are monolithic devices made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads with one side connected to the ground. Active VCC pin voltage clamp protects the device against low energy spikes. This device integrates an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is in a high impedance condition. Output current limitation protects the device in overload conditions. In case of long overload duration, the device limits the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as the fault condition disappears.

Breakout Board for UCC28019 and UCC28128 PFC Controller

This is a breakout board for UCC28019 and UCC28128 PFC controllers. This module enables users to build a high-power PFC (Power Factor Correction) controller. Active PFC uses the boost topology operating in Continuous Conduction Mode (CCM). The controller is suitable for systems in the 100 W to >2 kW range over a wide-range universal ac line input. The startup current during an under-voltage lockout is less than 200 µA. The user can control low-power standby mode by pulling the VSENSE pin below 0.77 V. Low-distortion wave-shaping of the input current using average current mode control is achieved without input line sensing, reducing the Bill of Materials component count. Simple external networks allow for flexible compensation of the current and voltage control loops. The switching frequency is internally fixed and trimmed to better than 5% accuracy at 25°C. Fast 1.5-A gate peak current drives the external switch.

Numerous system-level protection features include peak current limit, soft over-current detection, open-loop detection, input brown-out detection, output over-voltage protection/under-voltage detection, a no-power discharge path on VCOMP, and overload protection on ICOMP. Soft-Start limits boost current during start-up. A trimmed internal reference provides accurate protection thresholds and regulation set-point. An internal clamp limits the gate drive voltage to 12.5 V.

Note 1: The PFC controller module is published here. The second part (mainboard) is 350W Power Factor Boost Converter for Inverter-Fed BLDC and PMSM Motors.
Note 2: This module can accommodate two chips UCC28019 or UCC28180. Refer to the datasheet of both chips to select the components as per requirements.

UCC28019 Datasheet

High Power Bipolar Stepper Motor Driver with SPI Interface

This is a compact high-power stepper motor driver built for bipolar stepper motors. The driver can be controlled using a serial communication interface (SPI). It combines a flexible ramp generator for automatic target positioning with the industry’s most advanced stepper motor driver. Using external transistors, the driver ensures absolutely noiseless operation combined with maximum efficiency and the best motor torque. High integration, high energy efficiency, and a small form factor enable miniaturized. The complete solution reduces the learning curve to a minimum while giving the best performance in class. The project has the option to interface an external incremental encoder for easy control of position and step-loss operations.

Note 1: Refer to the datasheet of TMC5160 to understand the SPI interface and control system.
Note 2: This board only works with serial-SPI mode, it doesn’t support standalone mode.

Mode of Operation

MODE 1: Full Featured Motion Controller & Driver

All stepper motor logic is completely within the TMC5160. No software is required to control the motor – just provide target positions. Enable this mode by tying low pin SD_MODE. Install Resistor R2 0 Ohms to select this mode. Do not install R1.

MODE 2: Step & Direction Driver

An external high-performance S-ramp motion controller like the TMC4361 or a central CPU generates step & direction signals synchronized to other components like additional motors within the system.  The TMC5160 takes care of intelligent current and mode control and delivers feedback on the state of the motor. The Micro Plyer automatically smoothens motion. Tie SD_MODE high. Install Resistor R1 0 Ohms to select this mode. Do not install R2.

Mode Selection

  • Soldering R2 / not R1 = Internal ramp generator active with Trinamic’s 6-point-ramp (default mode)
  • Soldering R1 / not R2 = Step/Direction interface active for use with external motion controller (STEP =REFL, DIR = REFR)

Automatic Standstill Power Down

An automatic current reduction drastically reduces application power dissipation and cooling requirements. Modify stand still current, delay time and decay via register settings. Automatic freewheeling and passive motor braking are provided as an option for stand still. Passive braking reduces motor standstill power consumption to zero, while still providing effective dampening and braking! An option for faster detection of standstill is provided for both, ramp generator and STEP/DIR operation.

Encoder Interface

TMC5160 board provides an encoder interface for external incremental encoders. The encoder allows automatic checking for step loss and can be used for homing of the motion controller (alternatively to reference switches), or for software-controlled correction of step-loss or position stabilization. Its programmable pre-scaler allows the adaptation of the encoder resolution to the motor resolution. A 32-bit encoder counter is provided.

Key Concepts

The TMC5160 board implements advanced features which are exclusive to TRINAMIC products. These features contribute toward greater precision, greater energy efficiency, higher reliability, smoother motion, and cooler operation in many stepper motor applications.

  • StealthChop2™ No-noise, high-precision chopper algorithm for inaudible motion and inaudible standstill of the motor. Allows faster motor acceleration and deceleration than StealthChop™ and extends StealthChop to low stand still motor currents.
  • SpreadCycle™ High-precision chopper algorithm for highly dynamic motion and absolutely clean current wave. Low noise, low resonance, and low vibration chopper.
  • DcStep™ Load dependent speed control. The motor moves as fast as possible and never loses a step.
  • StallGuard2™ Sensorless stall detection and mechanical load measurement. CoolStep™ Load-adaptive current control reducing energy consumption by as much as 75%.
  • MicroPlyer™ Microstep interpolator for obtaining full 256 microstep smoothness with lower resolution step inputs starting from fullstep

In addition to these performance enhancements, TRINAMIC motor drivers offer safeguards to detect and protect against shorted outputs, output open circuit, overtemperature, and undervoltage conditions for enhancing safety and recovery from equipment malfunctions.

Control Interfaces

The TMC5160 board supports both, an SPI interface and a UART based single wire interface with CRC checking. Additionally, a standalone mode is provided for pure STEP/DIR operation without use of the serial interface. Selection of the actual interface is done via the configuration pins SPI_MODE and SD_MODE, which can be hardwired to GND or VCC_IO depending on the desired interface.

SPI Interface

The SPI interface is a bit-serial interface synchronous to a bus clock. For every bit sent from the bus master to the bus node another bit is sent simultaneously from the node to the master.  Communication between an SPI master and the TMC5160 node always consists of sending one 40-bit command word and receiving one 40-bit status word.

The TMC5160 scores with complete motion controlling features, powerful external MOSFET driver stages, and high-quality current regulation. It offers a versatility that covers a wide spectrum of applications from battery powered high efficiency systems up to embedded applications with 10A or more motor current per coil. The TMC5160 contains the complete intelligence which is required to drive a motor. Receiving target positions, the TMC5160 manages motor movement. Based on TRINAMICs unique features StallGuard2, Cool Step, DC Step, Spread Cycle, and Stealth Chop, it optimizes drive performance. It trades off velocity vs. motor torque, optimizes energy efficiency, smoothness of the drive, and noiselessness. The small form factor of the TMC5160 keeps costs down and allows for miniaturized layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products.  High energy efficiency and reliability deliver cost savings in related systems such as power supplies and cooling.
