My X axis on my cnc 1100 loses its place and the chatters and then will only move in the negative direction
Michael, welcome to the Tormach Forums!
This does sound like it may be better suited for a Technical Support Ticket, however. How to Submit a Support Ticket
This situation sounds very similar to a problem I had recently with a failing driver on my PCNC 1100. Katie at Tormach helped me troubleshoot it and sure enough, there was some burned wiring that is a telltale that the driver was failing. Like was suggested, open a trouble ticket, or just call tech support and ask for Katie. She’s an awesome troubleshooter.
