Linking User M codes 101,etc to external switch was created by microsprintbuilder

I have created some user m codes to open and close my chuck and move the tail-stock in and out. They work just fine. I would like to be able to use the existing switches on the control panel to do the same. The manual says you cannot have these pins in the hal file at all. So how can you control these items with a switch and a M-code?

Which pins? I think your confusing what the manual says.

Take a look at my Harding e configuration files, I have both M1xx and buttons for my collet closer.

A bit of info about the Hardinge collet solenoid, it is a toggle type ie. you energize one coil for a moment and the valve toggles to that position. You energize the other coil for a moment and the valve toggles to the other position. It does not need to be energized to stay open or closed.

# External Collet Open/Close Buttons
net collet-open-btn or2.3.in0 <= hm2_5i20.0.gpio.027.in_not
net collet-close-btn or2.4.in0 <= hm2_5i20.0.gpio.025.in_not
net collet-open hm2_5i20.0.gpio.043.out <= or2.3.out
net collet-close hm2_5i20.0.gpio.041.out <= or2.4.out

M100

#!/bin/sh
# open the collet closer
halcmd setp or2.3.in1 1
sleep 0.25
halcmd setp or2.3.in1 0
sleep 0.5
exit 0

M101

#!/bin/sh
# close the collet closer
halcmd setp or2.4.in1 1
sleep 0.25
halcmd setp or2.4.in1 0
sleep 0.5
exit 0

Your missing in your hal file:

loadrt or2 count=2

and change the or2.3's to or2.0 and or2.4's to or2.1, I have more than two or2's in my hal file.

Thanks, I did miss the loadrt count. I already have 3 so I changed it to 5. Now I get "and2.3.in1 does not exist". Is it not reading the user m code files?

I think and2 error has nothing to do with this. I must have changed something. I'll keep looking.

I changed the and2 count instead of the or2 count. It works! Thanks!

I also have a coolant switch (toggle on/ off) on the panel. what would be the best way to route that so it would override the control command. I was thinking classic ladder. or doing something like your pause/resume code.
