CNC 5040 z-axis problem
« on: December 30, 2020, 02:14:27 PM »
Hello,
I am new with cnc, we buy from china to cut some materials. Machine x.y axis work without problem. But problem is about z-axis.
z-axis think oposite than can be.
Machine when start cut, moves down and  then cut on up not down, and after program is finish return to down.
We change in artcam material thickess and from buttom  to top, but nothing change.
we change home limits from negative to positive and oposite for z-axis ( soft max 1 and soft min -255) but nothing change
Machine z-axis negative values is on up (sealing) and positive values on floor. But why machine moves always on negative values (sealing).
How to configure mach 3, to make the machine think oposite?
Controller is XHC with wifi controler.

Config -> Ports&Pins -> Motor Outputs -> Z-axis -> Dir LowActive
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

we test all other axis and all move oposite diretions, where to change these to reverse?

As TPS has already told you...

Config -> Ports&Pins -> Motor Outputs -> axis - change the Dir Low Active State for the particular axis which is moving in the wrong direction and save the change. Restart Mach3 to check that the changes have taken effect.

PEACE
