Hello long time no see. Been busy . This is the story so far . My Harrison lathe now has 2 new servo motors and drives fitted. Not wired to smoothstepper yet but they do jog on the buttons nice. Got smoothstepper and 2 breakout boards fitted and wired to index disk and all the limits .Just got 1 problem . All the m3 m4 and m5 commands work fine but speed commands are totally ignored and it spins as fast as the invertor will let it go . Got lots of gears but I would like to vary it a little. The volts on the bob's stay at 10 (both bob's) all the time 0 to 10000000 rpm its all the same . Any ideas its driving me nuts.
