Wired MPG pinout

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....

Reading Absolute Encoders

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 im...

Re: Using footswitch to pulse a LASER

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.

Re: Using footswitch to pulse a LASER

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 be...

Re: Using footswitch to pulse a LASER

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 footswitch ...

Re: Using footswitch to pulse a LASER

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

Using footswitch to pulse a LASER <answered>

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. CNC Welder.jpg Custom VCP.jpg It would be c...

Re: Creating a VCP Indicator Button

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

Re: Creating a VCP Indicator Button

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 th...
