Thanks for the information. Sorry for the late response.

I am considering using the Centroid Wired MPG (PN 11069) with a Galil motion controller to jog an X-Y stage in an SEM chamber. I have used this MPG with an Oak controller in the past and like it.
But I could not find a manual or wiring diagram showing how the encoder and the switches are pinned out ...

I plan to use two Yaskawa Sigma-7 servos / ServoPacks on a project. I would like to use their absolute encoder's burst output to determine axis position at startup, avoiding the need for limit/index switches. The X-Y stages (not the motors!) are in a high-vacuum chamber so switches are awkward to ...

I had not looked at the M100 / M101 codes. Very nice! Using them in a macro or program with a loop would make this simple. Thanks.
I would use a G4 to accurately time the LASER pulse, but the basic idea is the same.

Forgot to answer your last queeston...
All other actions (e.g. argon flood and lens-protecting air blast) can be done using VCP buttons.
But as you were perhaps hinting, would be very elegant to turn on the argon and air, wait a moment, do the pulse, wait a moment, then turn them off.

Would it be ...

Yes, I would just jog to the weld-head to the desired location (as identified by the red dot) and pulse the LASER. I could also just move the part by hand since it does not need to be clamped down.

Output #1 is assigned to SpinFWD.

As I think about this more, it is probably better if the ...

Here is a fresh report.
Since this is a rather generic question, I did not think it would be helpful.
Sorry.

I have built a CNC LASER welder around a 1kW Chinese Fiber laser. The LASER head (with galvo wobble) is mounted to a stepper-driven gantry. I am using an Acorn controller. It works very nicely and I will be happy to share more info if anyone is interested.

Just made the changes on two buttons to watch inputs instead of memory. Button images instantly followed inputs. Perfect!
Thanks again Allin1Chris.

Thanks for your advice.
That will be much less confusing than trying to figure out what the vast PLC logic is doing with memory locations.
I had read page 15 but then forgot about using inputs and latched onto the example that discussed using memory locations instead. My error.
You also mentioned ...
