HELLO bit of a wild card ..but i am running a romax wd1 for a friend he know zero about ...i managed to get all axis responding and have the xml from romax ..its in inch mach is set to inch steps are set to recommended 5300 ...its a closed loop that has two parrallel ports but im only using one at the mo no spindle attached as yet *ihave it
the problem is that when i jog from the ui or the keyoard everything is ok except the minus x which goes positive for about an inch then goes negative   at first i thought it may be motor tuning but the other axis are fine z and y are smooth no grinding ...im thinking the xml may be corrupted but i cant get any joy from romax they dont accept my emails ...any suggestions would be gratefully recieve ..thanks
