Ensure the two phases are correct for the driver…
If it doesn’t move at all, it’s likely the it’s not making a connection, if it nudges, one or the other wires wires may be swapped.
I did some testing and I swapped out the stepper driver for a new TMC2209 and it worked.

For this post, I just wanted to clarify that the Switch laser Control is going into the ground end of the laser tube?
Cathode of the tube goes to ground, this is also where you can put an inline mA meter.
The L input of the lps goes through a switch to ground. This enables the laser to lase at the pwm current level.
Hey I was able to get back to work on the laser cutter after a short break.
What do you specifically mean when “The L input of the lps goes through a switch to ground”? I just don’t know what a switch is in this case, unless you mean one of these?

Yes, any kind of switch… will work… very low voltage and current…
Alright I have everything wired up and I managed to fire the laser by using the button on the power supply. I then connected the machine to laserGrbl and was able to move the machine and home it with the limit switches. However I wasn’t able to fire the laser from the software.
The commands I did were:
M3
G1F500
S255
I already have the laser enabled on $31=1
Any thoughts?
