hi hood
it is a 20 amp servo pak ametek servos/us didital encoders from "lowcostcncretrofits"
the machine it is build by my
inside the controller box are 3 gecko320 drivers
the machine did run well before the modification
it runs well at this moment if i unplug the parallel cable from the comp /engage the servos/plug back the parallel cable and then jog around
or if i go in device manager /disable the parallel port/engage the servos/enable the parallel port and then jog around
i have fitted a second parallel port on the comp /set it as port 1 in mach but the problem is still there
i measured the voltage across the parallel cable (unplug-ed from the controller box ) and found 5 v on pins :3,7,8,10,11,12,13,15.
from those pins3 and 7 that have 5v on them corespond to x dir and z dir
my setup for the 3 axis is as follows:
step dir
x 2 3
y 4 5
z 6 7
