Hello
I am looking for a way to save gcode on an SD card in a laser cutter using a python application on a Raspberry Pi connected to the cutting board via a USB cable. I made a port in python but the Gcode commands do not allow me to save. I'm currently using something like this
M21 Use this command to mount the last-selected SD card or thumb drive.
M28 This command starts a file write.
G0 ...
G1...
M29 Stop writing to a file
This code only allows me to create an empty file on the card. I also tried to use the M110 code, but it caused numerous errors (Line number not changing, errors on the terminal).
Does anyone know what the correct code should look like?
Data:
Software version: Marlin 2.1.2.1(pins_CREALITY_V4.h - changed to work as a laser cutter)
Motherboard: Creality V4.2.2
