So I have hardly used my CNC in the last few years but am running Mach 3 on a Windows XP desktop. It had been working fine until one day my Bosch router quit working and it dragged across the work surface until I hit the stop button. I bought a new Bosch router but ever since then I have 2 places where my X axis 'jerks' and messes up my material. I'm not sure if something got messed up in the hardware or in the Mach 3 settings? It may not be related to the router hang-up at all. I rarely ever use it so it might have been months later that I noticed it. But wife wants me to make her a sign but I can't use it until I figure this out. Any ideas what might have happened or how to fix it? Should I just re-install the file for the controller? I bought this brand new off eBay several years ago and received the file needed for the machine. I don't remember how to install or set-up the file but plan to look at it tomorrow to try to figure it out.

Thanks
