    What size motors?
    If I recall, when a lot of people were building Joes 2006 machine, they were getting about 100ipm with 1/2-10 single start acme, and 300oz motors. That's about 1000 rpm at the motor.

    I have
    - HobbyCNC Pro (same driver chips).
    - 1/4-20 drive screw
    - 36V unregulated linear power supply
    - 300oz in motors
    - 1/2 microstepping

    I can push it to 40ipm, but that's pretty much it. For milling, I will go to 38 ipm max, typically 30 - 35 (material dependent, of course)
    I only have a home-made DIY hobby machine, and for a 20 thread-per-inch drive screw, 38 ipm is pretty respectable.
    You can do the math to figure out the steps per second.

    I have a HobbyCNC Pro and a 48V power supply. I forget what the microstepping is set to, but doubt that it would limit the max speed as long as the PC can keep up. I am using a 10 year old XP computer with a parallel port.

    My original router build had 10TPI ACME screws driven by 425oz motors. I could sometimes get 60ipm and would typically cut at 30-40ipm. Every once in a while it will stall and ruin the job.

    I switched to Ebay rolled ballscrews with 0.5cm threads, so effectively 5.08TPI. I could easily get over 100ipm and never felt the need to check the maximum speed. I usually cut at 60ipm and have never stalled the motors.
