Title: Up is Down!! Z axis is moving in the Wrong direction.
Post by: Mihaly on November 11, 2014, 09:11:45 PM

hi,

My Z axis is moving in the Wrong direction! (by which I mean up=down & down=up) Any idea how to fix it? Is it switching wires? Wonder which ones. And do you think I can hurt anything by switching the wrong ones?

Here's the machine's Motion Control Card:

Go into Config - Ports & Pins - Motor outputs and toggle, Dir Low Active setting.
You may then need to set up your homing directions to suit, under Homing Limits etc.
Pretty sure that will get you there. It's been awhile since I have done all that kind of tweeking.

You can also just check the Reverse box in Config > Homing/Limits
