The real Guru of Desk CNC is Fred Smith @
imserv@imserv.com, (E mail) or Ph # 248-486-3600..He is a busy person, but has always been able to answer any questions on Desk CNC. Wish I could wave a magic wand on this , but I've just never had another axis "creep" or activate when it should not have.
Like most things , it is probley real simple, just some small mistake in the set up or wiring.(been there , done that..)
