General Mach Discussion / Proma THC - Moves Z up but not down.
« on: November 02, 2012, 09:52:56 PM »
Just got around to wiring in my Proma Compact THC and it works in test mode, moving the Z axis up and down.  But when it's running g-code it will move up when the THC signals up, but it will never moves back down when the THC is signaling down.  The diagnostic page indicates that it sees the down pin high, but no movement.   I'm running licensed Mach3 with a Sound Logic PC-2-route M-2 breakout board.  And I have switched the up and down pins and still it move up, but not down.  I'd sure appreciate any help.  It' great having it just do half the job, it will be sweet when it does the whole job.  :)
