Well I may or may not need help! I found a way of doing it, but it seems very convoluted!

I wanted to attach a physical (real world) button for the auto tool zero function, to be used in conjunction with a touch plate. Incidentally, this button will also illuminate along with the 'on screen' tool change LED.

The LED / output I have working via the macro pump function, checking the status of the on screen LED and turning an output pin on/off accordingly

Re the button, I was looking on the list of OEM codes here:
https://www.cnczone.com/forums/attac...6/61017.attach
but I don't think it's listed.

The only way I could make it work is as follows:

I made a M35 macro, which is also part of the initilisation string in Mach3 config
M35.m1s reads

SetTriggerMacro 36

A second file (M36.m1s) has the normal zeroing logic for the touch plate

To call the macro from an external button I am using OEM code 301, and linking that using a 'hot key' to an OEM Trigger.

So the flow of events looks like this....

Input pin X is linked to OEM trigger Y
OEM trigger Y has OEM code 301 attached to it
OEM code 301 is linked to macro M36
M36 was linked at startup by another Macro, M35
M35 was defined in my Mach 3 startup string.

So that's it! It works, but seems overly complex. Am I missing a trick?

Also, this means there could only be one custom OEM trigger (301) defined. So I've now used that up!

No, you're not missing anything.

Another option is to use the macropump to monitor the button inputs, and call the M code from the macropump.

Thank you!

Hi - I have another issue related to this. I built a physical control panel with indicator lamps, my thought process was I would be able to control them using the MacroPump function. I have two parallel cards, so it's a fairly basic setup.

Within MacroPump I have entries like:

If GetOEMled(999) Then
ActivateSignal(Output7)
Else
DeActivateSignal(Output7)
End If

Overall I am looking to use:

[804] Cycle run (I also have a 'Cycle Stop' lamp, this is just the inverse of cycle run so doesn't use an output)
[805] Feed Hold
[806] Tool Change
[807] X ref'd
[808] Y ref'd
[809] Z ref'd
[999] Machine run (movement)

A single statement like this works, I can get to about four. Once I go beyond these, the lamp switching is hit and miss, it's also interfering with the VFD controller plugin i.e. the spindle doesn't stop at the end of the cycle. If I turn off MacroPump, everything works fine.

My PC isn't that powerful, so I'm wondering if I'm hitting some kind of limit? I can't think of any ways to write script more efficiently, unless if there was a way to use global variables and do the updates every x routine calls rather than every time? Or maybe hold the previous state of the LEDs and update the outputs only when something has changed

Any other thoughts greatly appreciated.

Thanks!
