PS021 is "ILLEGAL PLANE AXIS COMMANDED".

Is G17 active?

Do you have a Z in the G3 block?

Are you trying to do Helical Interpolation?

Post your program here so we can help.

try adding a G1 xy move before G3. i think it doesn't like the Z movement before the G3. even if the xy move doesn't actually move at all. like this:

You've programmed helical interpolation. Your control may not have that option turned on.

hes got x-y-z, so its a mill
its got g17, so its x-y plane(IIRC)
hes commanding x-z-i-j

shouldnt it be g18/g19 for x-z plane, AND I-K instead of I-J?
