Hello
I'm using MC_CamIn, and I'd like the cam to start at an absolute position.

I'm capturing a registration input, and I want the cam to start at a this position + offset ie the cm is loaded and waiting to run.

I'm sure with other motion controllers that this is possible, but I can't see an option to do this.

Thanks

I'd still like to make this work.
In the MC_CamTableSelect, I can set absolute or relative co-ordinates.

So rather than the cam being:
0,0
180,20
360,40

can I edit the Cam_A co-ordinates to (for example)
100,0
280,20
460,40

So the cam will start when the master axis reaches 100?

I ask, because the MC_CamTableSelect returns an error if I try this.

If your cam is modulo 360°, input 460 should be converted to 100.
