In reply to Balsaman's post, I've currently got three pc pwr supplies for each axis they all have the 12 & 5 vdc outputs, each one @12vdc has an output of at least 8A, to pwr the board itself I've got a 5v 2a separate pwr supply, yes the bench is somewhat busy. I'm using the software on a laptop that's running win98, because the testing app that came with the FET3 .... that's all that it will run on. I got that info straight from Rus himself after attempting for a week to get it running on WinXP. As for what software I'm going to run the system on, well I don't know yet because I can't get past this first part and I figure you don't buy the radio for a vehicle you don't have yet so I'm waiting on that. I was going to go with Mach2.... from reading other posts on the board. So my thinking.... am I right if the motors use 4.7A per phase there are 2 phases per motor ( two coils with center taps essentially ) so that = 9.2A per motor that I require to appease each axis, I need something on the order of a 30A pwr supply to get things working right ? I've made one motor work from the software (test app included ) with the FET3 but that's the extent of it.
any suggestions as to where I'm going wrong ?
thanks guys for the help,
