About this deal

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 So, this is a question about wiring to a Makerbase DLC32 v2.1, specifically for the laser module itself. 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) 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. GPIO32 at the spindle location is a controlable Ground only, this is how IT controls spindle RPM when being used for a mill

Command: esptool.py --port COM4 --baud 921600 --after no_reset write_flash --flash_size 4MB --flash_mode dout 0x00 C:\MKS DCL32\MKS-DLC32-main\MKS-DLC32-main\firmware\TS35\Laser\Normal\Board_V2.0\V2.0.8_H35_20220105_N.bin --erase-all The mainboard on my laser died. After researching it looked like the DLC32 was my best choice for a replacement. However, I’m a tad confused now that I’m connecting wires. Modify the configuration items. For specific configuration commands, please refer to Parameters configuration Another highlight of MKS DLC32 is that it can be used offline, without connecting to a computer, you can use the matching 3.5-inch touch screen for control, engraving, etc., which is very convenient. You can use PC software such as GRBLaser to config the parameters by sending commands, here is the list: COMMANDSI 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. MKS has also developed a supporting mobile phone APP, witch can edit pictures, convert pictures into engraving files, and transfer them to the main board in addition to addition to conventional control. Homing searches for a switch in the positive direction. Set axis bit (00000ZYX) to search in negative direction. The details can refer to XYZ-TABLE New here - Not sure this is the right Community for this question, so if not, please let me know so I might redirect. Modify the corresponding configuration items according to your engraving machine needs. For specific parameters configrations you can refer to Parameters configuration

Previously I used the original controller and connected the S9 to a raspberry Pi with Octoprint. But that doesn’t work as well as I was hoping for (main issue is that the laser can’t get information fast enough to engrave at full speed) Furthermore I didn’t have a way to control the laser (laser is not in my room but remote; computer is in my room). Mobile phone to control the RPi is not exactly convenient so I wanted to do it different.Harde limiet geactiveerd. De machinepositie gaat waarschijnlijkverloren als gevolg van een plotselinge en onmiddellijke stopzetting.Herplaatsing wordt sterk aanbevolen.

Inverts the direction signal. Set axis bit to invert (00000ZYX). The details can refer to XYZ-TABLE

For detailed wiring method, please refer to: https://github.com/makerbase-mks/MKS-DLC32/blob/main/doc/DLC32%20wiring%20manual.pdf Compare between MKS DLC and MKS DLC32 ITEMS File uploaded to Octoprint, then engraving from octoprint over USB works fine. Cutting from octoprint over USB works also fine.

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 Retract distance after triggering switch to disengage it. Homing will fail if switch isn't cleared. This hardware does not have UART capability to communicate with "smart" drivers, all driver amperage must be set by normal potentiometer method. HOWEVER one person has had success in using sensorless homing by jumping the DIAG pin on a TMC2209 directly from the driver to the GPIO of the corresponding endstop to detecting the stall occurrence. While not a method of UART communiccation for smart features, it can be used to do sensorless homing. The config must be re-written for that feature, and further tested. ¶ Pin Numbers

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. 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.
