Re: SLO-SYN 12.7 Amp motors

Charles,
Bridgeport drove those motors with 8 amps. The power supplies are good heavy
duty power supplies capable of about 20 amps each. No reason to get rid of
them unless you just want to conserve a little power.
The Microkinetics 8010 half step drivers should work fine with EMC and the
Bridgeport power supplies. I think the main thing in using these drivers is
getting the timing correct in EMC. I have had good results on the Bridgeport
using the 8010 drivers and ahha software. I remember that I had to change
the step signal out put from low = true to high = true for the 8010 drivers.

am ready for some suggestions on the hardware needs and just where I should
look to find what I need. I have a head start as this machine was running
as a CNC. I don't have much left of the original control as they were
stripping the machine and sending the parts out in the dumpster. The
machine came to me as scrap, but it is very good iron. I just need to give
it a new control. I have the old power supplies, but I think an upgrade is
warranted here.
