HANLEES Makerbase MKS DLC32 Offline Controller 32bits ESP32 WIFI GRBL TFT Touch Screen for desktop laser engraving machine (DLC32-TMC2209 Kit)

Product Information

I have the same data sheet with schematics, and yes, this is my NEW DLC32 v2.1 configuration. But that’s not how my original board is. It has two 2-pin connectors, one a 12V and the other the TTL. The cabling from the laser is 3-pin at the laser, but it then splits out to two 2-pin harnesses at the board end. One of those 2-pin harnesses houses V and G and goes into the 12V connection on the original board, and the other 2-pin harness has the 3rd cable going into only the S pin (leaving the other pin-slot empty) and plugs into the TTL connection. 3 cables across two 2-pin harnesses, as the original board is configured. But to get that same cabling to work on the DLC32 board, I’d have to cut the wires at the board end and solder them into a 3-pin harness for the TTL connection, because I can fit the 12V 2-pin harness into the 12V connection, but I can’t plug the other 2-pin harness into the 3-pin TTL connector on the DLC32. Inverts the direction signal. Set axis bit to invert (00000ZYX). The details can refer to XYZ-TABLE

Most of the low cost controllers on these machines use a 8 bit based pwm. That means they are slicing the PWM based on 0 to 255 or 256 steps from zero power to full power. The STM32 MCU has a 16 bit pwm so it’s resolution is 0 to 65535 or 65536 (steps from zero to full power.) That is the advantage they advocate and properly so. It is an advantage to have finer power control. I found the latest firmware on github and flashed. Here is console from flash: C:\MKS DCL32\MKS-DLC32-main\MKS-DLC32-main\firmware\TS35\Laser\Normal\Board_V2.0\V2.0.8_H35_20220105_N.bin Dug out my fystec E4 grbl esp32 stuff …loaded into VSC with platformio and it compiled ok… Its about 400megs though so best just send you the machines file (4kbytes and text too) if youre still interested…along with some instructions on how to use it? File uploaded to Octoprint, then engraving from octoprint over USB works fine. Cutting from octoprint over USB works also fine.JKWilborn - I have attached a photo I took of the board. Yes, it’s a crappy photo. Sorry about that. Like I mentioned, I have a shake I can’t much control most days. Wrote 4194304 bytes (1099450 compressed) at 0x00000000 in 21.4 seconds (effective 1570.3 kbit/s)... The PWM frequency of the MKS DLC32 can be as high as tens of KHz (the traditional scheme is lower than 980Hz), which fully meets the needs of various semiconductor laser heads. The engraving effect is more delicate than the traditional desktop engraving scheme, and the grayscale expression is smoother.

Open the LaserGRBL software or LightBurn or other serial tools on the PC (the default baud rate is 115200)Maximum X-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances.

Harde limiet geactiveerd. De machinepositie gaat waarschijnlijkverloren als gevolg van een plotselinge en onmiddellijke stopzetting.Herplaatsing wordt sterk aanbevolen. Sets the G2 and G3 arc tracing accuracy based on radial error. Beware: A very small value may effect performance.

MKS DIY Control Board - Engraver:

Does this board communicate in the way you favor? Does the board have USB Type-A port? USB Type-C port? Mini-USB port? Micro USB port? WiFi expansion? I can get the laser to move in the desired direction with the cursor arrows in Lightburn but as soon as I start a job (or draw a frame), the head wants to move to positive coördinates (so, to the left of the laserframe and over the front of the laserframe)
