Hi..

This is a weird one, although it would be nice if someone said 'that's a common problem, here is the fix'..!

When I jog my machine X+, it moves at about 1800 (Mach 3), but when I jog X-, it goes at 4000.. Now, if I jog at X- (4000), then jog the Y axis, the Y axis moves at full speed...

BUT..! If I jog X+ (1800), then try to jog the Y axis, it moves at half speed...

Really cant work out what is going on but this problem has made for some interesting parts cut on my cnc router, weird arcs, wrong size sections etc.. I have a feeling this might be electronic rather than mach, just dont understand why it would do this..

Any ideas guys?

thanks
Steve..
