I tried to see what the driver inputs were by using my oscilloscope, but the signals are referenced to a floating ground, what I got was allot of noise. I could use two channels to get a differential between the signal and its ground, but I only have two channels, so I could not compare the timing of two signals. So far my guess about the signals is based on noisy traces and reverse engineering a small bit of the controller output circuit. I suppose I could continue to trace the circuit to see what signals are up the line. I just realized, I could probably get by the scope problem by probing the far side of the optocouplers in the driver or setup my own optocouplers referenced to the scope ground. I guess this is going to take a little more effort on my part. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/Bandit CNC) ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
