Hi everyone,

I need help with my laser not firing. Im not sure what the issue is, wether it is hardware or software. My laser is plugged into the "laser" port and I have gotten it to work in the past but then I took a month break and came back and I'm not sure what the issue is.

My laser is 10W.

Below is my config file. Can someone tell me if im missing something and what commands to test it?
I tried turning it on with "G1 X50 S180" but it does not work.

Thank you

Hello everyone,

Ive been trying to solve this issue for a few days now (after taking a month break lol) and now I'm really lost. I am unable to tune sensorless homing for my laser cutter. Below are the gcode files, and motor specifications.

The X length is 750-800 units
Stepper motor part number: 17HS16-2004S1

If anyone could send me corrected files or any help that would be great!

LMK if you need any other info.

Please note that the values in the current gcode files are probably not correct lol

homex.g

M400 ; Wait for current moves to finish
M913 X70 Y70 ; drop motor current to 70%
M400
G91 ; relative positioning
G1 H1 X-320.5 F1200 ; move quickly to X axis endstop and stop there (sensorless homing)
G90 ; absolute positioning
M400
M913 X100 Y100 ; return current to 100%
M400
