Debounce and Base-Thread Help Needed was created by Mr. Technical
Hi Guys,
I recently installed a touch plate on an older LinuxCNC router installation and have tested it. While it works fine sometimes, it often throws a message about a jog move with probe input triggered. I chalk that up to needing a debounce function, which I am trying to get working.
I added the following to the custom.hal file:
# Include your custom HAL commands here
# This file will not be overwritten when you run PNCconf again
#added 1-22-20
#add this to custom.hal for probe debouncing
#change delay and pin number to fit your needs.
loadrt debounce cfg=1
setp debounce.0.delay 300
addf debounce.0 base-thread
net debounce-probe-in debounce.0.0.in<=hm2_5i25.0.7i76.0.0.input-04-not
net probe-in debounce.0.0.out=>motion.probe-input
#end of probe debouncing.
And added this to the M22-R6Probe.hal file:
# ---probe signal---
#remove the following two lines from (your machine).hal to
#make debounce fix added to custom.hal file work.
#This essentially breaks the original nets in the next two lines
#so they can be reconnected to the debounce function.
#net probe-in => motion.probe-input
#net probe-in => hm2_5i25.0.7i76.0.0.input-04-not
# on 1-19-20,added "-not" in previous line to invert probe-in signal due to adding 4.7K pull up resistor to circuit.)
# tool is grounded, and plate is tied to 24VDC through 4.7k resistor at input 04)
When I try to start LinuxCNC after those changes, I get the following debug message:
Debug file information:
Can not find -sec MOT -var MOT -num 1
Can not find -sec IO -var IO -num 1
Can not find -sec LINUXCNC -var NML_FILE -num 1
Can not find -sec EMC -var NML_FILE -num 1
HAL: ERROR: function 'debounce.0' not found
custom.hal:15: addf failed
10694
PID TTY STAT TIME COMMAND
Stopping realtime threads
Unloading hal components
I've attached the original files below for reference. Does anyone see what is wrong with how I'm trying to do this?
I suspect that the base-thread function is not loading properly, but don't know why.
All help is greatly appreciated.

With Mesa cards a base thread is not normally used.
You could use debounce with an appropriate number
of servo thread periods.

Thanks for the info.
So, instead of: addf debounce.0 base-thread
I would use: addf debounce.0 servo-thread
What is typically a good delay value to use for debouncing a touch plate with servo-thread?
That is, what would I enter in this line copied from above?
setp debounce.0.delay 300

You might try 3 to 10 (3 to 10 ms at a 1 ms servo thread)

Dont use to many
SPACE Lines and also Comment lines #
from 2.8 update to 2.9 id id run in Problems on this issue
someone told me this
i removed this lines to a min at 2lines to the next and Wonders disapeard
Remember the planer does run to this files on regular bases this might interfear the system at Speed cuting

Is this true? As I like to add add a few spaces and ### In my files as I find then easier to read.

This is not true. The HAL file is parsed exactly once at system startup. It is used to move all the HAL pin pointers to the right places in the shared memory section. From that point on the HAL file is never used again.
