MKS
DLC32 motherboard kit, which is an offline engraving master control kit
developed
for desktop engraving machines. The hardware is equipped with
a 32-bit high-speed ESP32
module, integrated WIFI function, and
directly drives a 3.5-inch touch color screen; it can
realize fast
engraving and WEB web pages. Control, mobile phone APP control and other
functions.
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.

There are several compiled firmwares that can be downloaded here:
For Laser, normal machine
For Laser, CoreXY machine
For CNC, normal machine(For beta)
For CNC, CoreXY machine(For beta)
The
firmware of MKS DLC32 has been burned with laser normal machine before
leaving the factory. If you need to update the firmware, you can follow
the update instructions here.
We
have developed MKSLaser, the App for mobile phone, which can connect to
MKS DLC32, control movement, edit image, upload files and so on. Now
the Android verison has been uploaded to Google Play. And the one for IOS is still under development. 
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.
You can use PC software such as GRBLaser to config the parameters by sending commands, here is the list: xxxxx
| COMMANDS | PARAMETERS | DESCRIPTION |
|---|---|---|
| $0 | 10 | Sets time length per step. Minimum 3usec. |
| $1 | 5 | Sets a short hold delay when stopping to let dynamics settle before disabling steppers. Value 255 keeps motors enabled with no delay. |
| $2 | 0 | Inverts the step signal. Set axis bit to invert (00000ZYX). The details can refer to XYZ-TABLE |
| $3 | 1 | Inverts the direction signal. Set axis bit to invert (00000ZYX). The details can refer to XYZ-TABLE |
| $4 | 0 | Inverts the stepper driver enable pin signal. |
| $5 | 1 | Inverts the all of the limit input pins. |
| $6 | 0 | Inverts the probe input pin signal. |
| $10 | 1 | Alters data included in status reports. |
| $11 | 0.01 | Sets how fast Grbl travels through consecutive motions. Lower value slows it down. |
| $12 | 0.002 | Sets the G2 and G3 arc tracing accuracy based on radial error. Beware: A very small value may effect performance. |
| $13 | 0 | Enables inch units when returning any position and rate value that is not a settings value. |
| $20 | 0 | Enables soft limits checks within machine travel and sets alarm when exceeded. Requires homing. |
| $21 | 0 | Enables hard limits. Immediately halts motion and throws an alarm when switch is triggered. |
| $22 | 0 | Enables homing cycle. Requires limit switches on all axes. |
| $23 | 0 | 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 |
| $24 | 300 | Feed rate to slowly engage limit switch to determine its location accurately. |
| $25 | 1000 | Seek rate to quickly find the limit switch before the slower locating phase. |
| $26 | 250 | Sets a short delay between phases of homing cycle to let a switch debounce. |
| $27 | 1 | Retract distance after triggering switch to disengage it. Homing will fail if switch isn't cleared. |
| $30 | 1000 | Maximum spindle speed. Sets PWM to 100% duty cycle. |
| $31 | 0 | Minimum spindle speed. Sets PWM to 0.4% or lowest duty cycle. |
| $32 | 1 | Enables laser mode. Consecutive G1/2/3 commands will not halt when spindle speed is changed. |
| $100 | 80 | X-axis travel resolution in steps per millimeter. |
| $101 | 80 | Y-axis travel resolution in steps per millimeter. |
| $102 | 80 | Z-axis travel resolution in steps per millimeter. |
| $110 | 6000 | X-axis maximum rate. Used as G0 rapid rate. |
| $111 | 6000 | Y-axis maximum rate. Used as G0 rapid rate. |
| $112 | 6000 | Z-axis maximum rate. Used as G0 rapid rate. |
| $120 | 500 | X-axis acceleration. Used for motion planning to not exceed motor torque and lose steps. |
| $121 | 500 | Y-axis acceleration. Used for motion planning to not exceed motor torque and lose steps. |
| $122 | 500 | Z-axis acceleration. Used for motion planning to not exceed motor torque and lose steps. |
| $130 | 285 | Maximum X-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances. |
| $131 | 272 | Maximum Y-axis travel distance from homing switch. Determines valid machine space for soft-limits and homing search distances. |
| $132 | 80 |
