Have you run the driver test to see what your pulse is like?

I know that port does work though, as it was with the smooth stepper.The SS doesnt use a parallel port.
thanks for the responses,
did you guys use another way to power the spindle or did you power it with the made or bought psu and transformer?
Can i use a vfd with the supplied spindle on the Bridgeport and do you recomend any vfds?Yes if its a 3 phase induction motor you can use a VFD, personally I have found that you will lose a lot of torque when you go below about 20% -30% normal speed with a VFD so I kept the variable sheaves as well and just adjust with a combination of VFD (external pot ) and sheaves. As for VFD afraid I have no recommendations, I have two I have used, a Mitsubishi and a Hitachi and both work well.
Would you definately use a smoothstepper for this retrofit or would you do without one?Personally I would but probably no huge benefit if your computer can put out a nice clean pulse. The good thing about the SmoothStepper is if in the future you decide you need it there is very little rewiring to do, all you would need is to remove the cables from the parallel ports and plug into the SS.
Just curious using a g203 gecko over all the others with the same specs. Should of I picked a different gecko for my application or are they all the same except 203 has more protection?
