I have 200oz-in stepper running an ~35lb gantry using a 24V 12A PS. Each axis is receiving upto 3A using a hooby board. I am able to achieve cut speeds over 2 ips. I know I can get more if I tuned my gantry better, but heck - its only plywood.
Doing some conversions, it sound like the steppers you have are ~1700 oz-in units. From my reading, the higher the torque the less top end speed unless you have timing belts to take advantage of the steppers. I also thought a machine requiring this size stepper was better served by servos? Some things to check: Gantry racking Pretensioning your lead screws Proper alignment of your leadscrews and bearing mounts Proper alignment of your motor / leadscrew Proper tightening of all axis rails This weekend after 10 minutes of messing with leadscrew bearing mounts and the lovejoy couplings, I went from a lousy 0.5 ips to over 2 ips. My steppers even sound happier now. Hope that helps some. ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
