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

Product Information

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 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. 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.

Maximum Y-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances. 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. VVVV: use this value to try and find your confortable max with your mA meter for your maximum power. The lower the Value, the higher the mA on your meter. Sugested Start Value at 3000, until you get your desired mA. (2200 produced 16mA usage on my setup)

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.

Grbl controls the mechanics of your machine. It does nothing except execute the instructions you send it, one at a time. Every time your laser makes a spot, it’s executed a line of code. That’s why it produces so much data for an image. such as filament-run-out sensor, Power-off resume, auto-leveling sensor, expansion ports(12c, SPI, UART, CAN), etc... Choose the baudrate which can be over 115200(The greater the baud rate, the faster the transmission speed, but the greater the chance of transmission errors). The first thing you should look at is the Processor. What is its Architecture (32-bit or 8-bit)? How fast could it proceed(Main Frequency, RAM) and how large could it storage (Flash size)?

New here - Not sure this is the right Community for this question, so if not, please let me know so I might redirect. Sets the G2 and G3 arc tracing accuracy based on radial error. Beware: A very small value may effect performance.
