I'm new to CNC and Mach3 and I'm frustrated with my x axis changing (my rout gets off and if I 'go to zero' the x is off.) It happened earlier after the central AC in my shop kicked on. The router rpms dropped momentarily and the pattern was obviously off after that. I ran the code again with the AC, dust collector and air compressor off and it did it again! This is the third time out of a dozen attempts that it has occurred. Any ideas?
Thanks,
Jim Williams

A router can create a lot of noise on the leads to the motors and cause problems so make sure they are shielded and grounded properly.
I would also recomend that you run your machine off a dedicated circuit which will not be influenced by other power users. The circuit should be suitable for total of all the users. In the case or a motor 1.5 to 2 times normal current draw ( i don't remember what code states ).
Try lowering your acceleration and velocity first and see if it makes a difference. Say 30% below max velocity and test.

I had the computer plugged in to the same circuit as the CNC... I separated them and ran a test run with no problems. I'll play with it some more before making a finish run.
Thanks for the reply!
