General Mach Discussion / Re: Drifting in the Y axis
« on: December 18, 2009, 03:19:34 AM »
Thanks everyone for your input. Just to answer a few questions, the PC is a dedicated and high powered machine. It has just the OS (XP) and Mach3 on it and is not connected to any other device.
I did some testing a while ago and if I zero Y to something solid then move + & - in Y a few times and check Y again I can see it has drifted + in Y. Thing is it's fairly repeatable and only appears to loose steps in the -Y direction but not the +Y. I've cranked the Y axis by hand and it feels fine. I've checked the backlash and it's 0.02mm, which is fine. I'll check the couplings and any other fixings I can find. Thanks again.
