Hello,

The drill bit of the CNC is not spinning and I have no idea why!  
I have no error message…  
I’ve looked into previous post without success.  
Any tips and tricks are appreciated !

Here are my settings  
-Snapmaker A350  
-Luban 4.13.0  
-In the gcode of my file, there is everything that is needed I think with the M3 P100 and the F1500 commands :

Are you able to turn the spindle on and off manually through Luban’s workspace?

I could not.  
However, one more reboot did the trick and it’s back to normal. Very weird behavior.

So it’s now solved but… by chance ?!

Double check all your connections, might be a loose connection from the toolhead or the controller.

Glad to know it works now. Sometimes things just need a good reboot.
