need some sugjestions.

I have a Taig mill and bought it 3 or 4 years ago from deepgroove1. I was new and I dew some jewelry work, and an occasional part for my motor cycle. I have been reading different threads about steppers, drivers and control's I switched to EMC2 From Mach 3 just because Windows does so much in the back round, it helped a little.
My Question is which stepper motors should I be using on my taig right now I have 269 0z on the z and the other 3 are about half the length of the one on the Z but they do not have an oz for holding torque. I am going to go with the Geko 540 drive so I would like to cut a little faster (now I have to limit my rapid (G0 are changed to G1 F12) just so it does not stall and lose step, the z is the worst fo this.

Any help would be great.

You need to match the stepper drive ratio/motor/driver/power supply for best performance. Many folks get caught trying to use too big a motor to make up for poor planing in other area. On the Taig I have found the 166 oz-in motors perform wonderfully. I use them with the G540 and a high quality 48V power supply. (I was just out in the shop cutting aluminum at 20+ IPM with a 3/16" end mill with this combination.)

Thanks Jeff ILike I said I think that is what came with mine for the XYand A but I think the Z is 269 so I should just start with trying them on the Geko 540 and then go from there. Maybe that will be the plan.

again thanks
