When I did the research for my plasma table (500 IPM) I found that good quality stepper drivers and voltage along with proper gearing made all the difference in speed. I went with a 63 volt power supply to obtain the best speed from my steppers. There is a ton of information on the EMC wiki site on this as well as a couple of spreadsheets to help you figure it all out. I studied the torqe curves for my steppers to find the rpm I wanted them to go at the rapid speed.
and you don't mention your setup so it is hard to guess what you have to know if anyone has a similar setup. In my case I used: Gecko G203v drives Antek 63v power supply Automation Direct steppers stp-mtr-23079 CNC4PC BOB John On 2 Jan 2009 at 18:07, aaron Moore wrote: > Hi > > Having built a 1.5 m x 1.5 m CNC gantry router used for woodwork, I > am > still amazed that it works as well as it does, however I am now > thinking > that the axis should be moving a little bit faster ( I recently > costed a > job that would have taken 15 hours to cut which seems a bit > excessive). > > It is set to run at 15mm per second max velocity, above that speed > the > steppers start screaming and miss stepps.
