Peter, that was it. For some reason I thought that doing this net x-pos-cmd axis.0.motor-pos-cmd => hm2_5i25.0.stepgen.03.position-cmd hm2_5i25.0.stepgen.00.position-cmd net x-enable axis.0.amp-enable-out => hm2_5i25.0.stepgen.03.enable hm2_5i25.0.stepgen.00.enable
was enough. I set up the 00 and 03 joints with the same parms. Thanks! I found other source of a problem. Chipmunk must have gotten trapped in the garage and decided to hide out in my box that has my power supply and drivers (small hole on one end). Found a few acorns in there. I was getting other odd issue and it turns out one of my direction wires got pulled almost loose. Ugh. Glad he didn't chew anything. Gotta get the cats in here....
