I've run into a new problem with my Mach3 which is running my CNC router.
For a period of 15 minutes or so, the cut became totally distorted with all X, Y, and Z axis movement shifted...
But it then resumed cutting correctly!!!!
The only variable I can think of was the use of a nearby portable electric drill...
I'm going to try and attach a photo of the problem.
Any insight will be appreciated!
