Main difference is the speed. Cutting obviously is done at a lower moving speed so the number of instructions sent over wifi is not so great. However: engraving over USB (Octoprint) or WiFi (lightburn on my laptop) is TWICE as slow compared to engraving directly from SD-card in the MKS DLC32. So for engraving bigger images, the SD card in the laser is the way to go. The mounting holes and board size of MKS DLC32 are compatible with MKS DLC, and the it can also be used with the LaserGRBL and LightBurn PC software. 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. Sets the G2 and G3 arc tracing accuracy based on radial error. Beware: A very small value may effect performance. Most MKS 3d printer boards are compatible with A4988, TMC2208/TMC2225, and TMC2209/TMC2226. If the board have external Stepper driver ports, you can connect stepper drivers of larger current such as TMC 2160-OC/TMC 2160-57.

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?

JohnJohn - I will try to do that tonight or tomorrow. Lasering is a hobby and life takes up the other 99% of the hours in my day. Well, that and sleep. But less so on the sleep the older I get… Does it matter that I don’t have the laser connected when I run that command? The steppers are connected, but because of the pin harness issue I haven’t attached the laser yet. Though I did manage to find the right 3-pin harness while in town this evening, so if I need to I can try to rewire to the correct harness.

When you want to use MKS DLC32 to install to a new machine, you generally need to configure parameters to fit your engraving machine. There are two ways to configure parameters, one is to configure through the configration file, and the other is to configure through the PC software. Configure through configuration files 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.binesptool.py --baud 300000 --chip esp32 --port /dev/ttyUSB0 write_flash --flash_mode dio --flash_size detect 0x0 TS35/Laser/Normal/Board_V2.0/V2.0.4_H35_20211123_N.bin 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. For software PWM control on K40, IN on TTL connection, G next to IN to G on TTL. No need for Enable

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? Maximum Z-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances. Sets a short hold delay when stopping to let dynamics settle before disabling steppers. Value 255 keeps motors enabled with no delay. GPIO32 that is located at TTL section, will deliver up to 5v of power to trigger the laser, this is how you get PWM control is by the firmware varying the voltage. Retract distance after triggering switch to disengage it. Homing will fail if switch isn't cleared.I use the Makerbase MKS DLC32 board as a controller, which is an offline engraving master control kit designed for desktop engraving machines. The hardware is equipped with a 32-bit high-speed ESP32 module, has built-in WIFI function, and directly drives a 3.5-inch touch-sensitive color dislpay.
