Hi Tom,
These are the screen shots and data files for my current setup. Some things you may want to know are the extent I got with increasing the P setting. X is rack and pinion drive and made it to 8 before going unstable. I reduced it to 7. The Y is acme 1/2-10 leadscrew and made it to 35 before being reduced to 17.5. It got very noisey as i went above 17.5. The Z is a 5 thread 5/8" ballscrew and made it to 10 before being reduced to 9. The motors are all noisey for some reason. I cut a part at 50 and 25ipm they were dead on for measurements after adjusting the steps but were no good on the corner radius. they were rough and odd shaped and did'nt show up at all below 1/8" radius. Any help is much appreciated. Thanks.
