You just click on the drop down, click Axis > Tandem Axis > pick whatever suits your tandem axis, usually it's Y, so Y2 Tandem StepGen.

That's it really.

The only thing that is confusing is you may have to invert the direction for one of the Y motors. It will be listed under that Joint, but it's confusing because it's next to "Unused StepGen" then Dir Gen-B, and you can click Inv there.

I show it clicked in this view, just so you can see it, you'll have to figure out if you need it or not.

This image shows Z Axis stepgen inverted, or am I losing my mind?

I am having the same issue with not being able to home the X axis (the tandem in my case).

Yep, you are correct. This catches me out a lot as well, the DIR pin is above the STEP pin.

No dice getting Qtplasmac to home my tandem X axis. I will try installing Plasmac Monday and see if I can get that to work. I jumped the gun trying to install a beta on my first go round!

Homing is done by LinuxCNC, QtPlasmaC should have no effect.

What is it doing/not doing?

When I load up QtPlasmac I 'power' up the machine and clear estop... then click on the 'home' buttons for x y and z. The y axis and z axis 'buttons' light up.... the x does not. When I jog the machine I have one X (the tandem) that will not move. I think I am having the same issue Clive is/was having.

Can you post a compressed file of your config.
