7i96 Probe Problem

I hooked my probe up to my old system and it worked fine just as it has for several years. I think maybe the differences in the system maybe the problem. Old system is Dell Optiplex 755 built in 2008, dual core 1.8 ghz, 2 gb ram. New system dell i7-7700 3.6ghz 16 gb ram. It looks to me like the new system is so fast it is picking up bounce where the old system was so slow it didn't see it. There is one difference in the hookups. My motors are have six wire and came from hobbycnc. On the old system all six wire were hooked up on a hobbycnc chopper board. I am now running on four wires with tb6600 drivers. Can you point me toward a debouncing tutorial?

I am running Stretch with 2.9 cnc on the old system. On the new is Buster with cnc 2.8.

Its seems more likely that there is a difference in probe handling
between LinuxCNC versions 2.8 and 2.9

A single debounce component would be setup like:

loadrt debounce cfg=1
addf  debounce.0 servo-thread
setp debounce.0.delay 10

net raw_probe hm2_7i96.0.gpioXXXX debounce.0.in
net probe_in debounce.0.out motion.probe-input

Probe worked on Linuxcnc version 2.9, 2.8, 2.7 and probably 2.6 on the old system. Should I try to install 2.9. I have no idea where what you show above goes.

They can go anywhere in the hal file (but you need to change the existing connections)

I put it at the beginning of the file and I am still getting the error. I changed
net raw_probe hm2_7i96.0.gpioXXXX debounce.0.in
to:
net raw_probe hm2_7i96.0.gpio0001 debounce.0.in
Is that the right syntax?

Correction on last post.
The changes were not saved because I did not use sudo.
I did save the changes and Linuxcnc would not run.

I put this in my Custom Hal file and no matter what I call the pin linuxcnc will not run and I get this error: ./custom.hal:7: Pin 'hm2/7i96.0.gpio001' does not exist. I have called it 0001, 001, .001 so anything I call it does not work.

comment the broken  line out, open linuxcnc and halshow, review the pin name to get the correct name and edit your hal file
