HI, first time posting here!!!
im looking for some guidance, i've been having problems with my mach 3 at the moment of running the program. when its on the line to turn on the spindle it shows me an error, ill attach the pictures of the error, i've reinstalled the program and no luck, changed the post processor  and the same result, in the past it was working fine, i've manually input "S12000" and the same error pop up.
