hi folks,

I recently bought a K40 and upgraded it with a Gerbil Kit.

I was working in LaserWeb all perfectly good. But… laser quality was not that good. So I was trying LightBurn. LightBurn does offer an option for the Gerbil board to choose. It has the right workingarea dimensions and also knows my home position is in the upper left corner. all good.

Until I hit the go to home button. than my laserhead was trying exit the box on the bottom left corner. ugly sound.

I turned off my machine and after that nothing…
not in laserweb not in lightburn.
jogging or moving to another position is not working.

the motors looking ok… I can move the head when machine ist turned off, and when on… it has a tight grip.

I have the feeling something went wrong in my setting:

I also get an error:
Warning: Gcode out of machine bounds, can lead to running work halt
jog(X,10,1800)
jog(X,10,1800)
Jog will use 10 mm per click
Warning: Gcode out of machine bounds, can lead to running work halt
jog(Y,-10,1800)

I’am one step closer… I change USB port.
now I can jog in Y axis… only in laserweb.
but as soon I choose X nothing happens and Y is not working eather than.

X axis doesn’t work because you set speed to 0 see $110
To change homing direction, you must set the right mask at $23, see https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration

@Ben_Koch YES… YES …… IT WORKS…
so jogging is now fine again… I still can’t understand why its value got changed.

I can move the head now. and set zeroe and return home.

all good. thank you so so much. <3
