Re: [CAD_CAM_EDM_DRO] Step/Direction puzzle

Here is a guess ..... (1) The 48 volts @ only 1 amp is a bit weak, and (2)
Check your +5 volts, to your opto's... I had the simular problem, found out
the amperage wasn' t enought for my 12' cables to the computer! This even
stumped the experts at Gecko!
