I picked those numbers with what looked OK on the stepgen wizard. I'll scale them back for now until I get more comfortable with the new/rebuilt machine.
How would you guys go about testing the limits? I used the the stepgen wizard to make it repeat back and forth and kept increasing it. I stopped above 500 or so ipm velocity and something like 60 acceleration. I haven't actually caused it to lose steps yet. If anyone is interested... I am using a 3:1 rack and pinion setup from cncrouterparts ( http://www.cncrouterparts.com/rack-and-pinion-drive-nema-23-p-50.html). ------------------------------------------------------------------------------ EMC VNX: the world's simplest storage, starting under $10K The only unified storage solution that offers unified management Up to 160% more powerful than alternatives and 25% more efficient.
