PlasmaC torch starting problem (Solved with help from the famous three)
No, the idea here is to use the current sensor as an Arc OK signal.
You would need to change PlasmaC to mode 1 in the in file and you would need to enable the following in your connections.hal file.#net plasmac:arc-ok-in ***YOUR_PLASMA_ARC_OK*** => plasmac.arc-ok-in
Is this the correct file: plasma_machine_connections.hal I don't see any arc-ok-in
# Keep your plasmac i/o connections here to prevent them from
# being overwritten by updates or pncconf/stepconf changes
# Other customisations may be placed here as well
# This file is built by the configurator in your configuration directory
#***** debounce for the float switch *****
# the lower the delay here the better
# each 1 is a 0.001mm (0.00004") increase in probed height result
loadrt debounce cfg=3
setp debounce.0.delay 5
addf debounce.0 servo-thread
#***** arc voltage lowpass cutoff frequency *****
#***** change to the cutoff frequency you require *****
setp plasmac.lowpass-frequency 0
#***** the joint associated with the Z axis *****
net plasmac:axis-position joint.1.pos-fb => plasmac.axis-z-position
net plasmac:arc-voltage-in hm2_7i96.0.encoder.00.velocity => plasmac.arc-voltage-in
net plasmac:float-switch hm2_7i96.0.gpio.003.in => debounce.0.0.in
net plasmac:breakaway hm2_7i96.0.gpio.004.in_not => debounce.0.1.in
# net plasmac:ohmic-probe {YOUR OHMIC PROBE PIN} => debounce.0.2.in
# net plasmac:ohmic-enable plasmac.ohmic-enable => {YOUR OHMIC ENABLE PIN}
net plasmac:torch-on => hm2_7i96.0.ssr.00.out-00
# a 1 here allows multiple tools to be used
# gcode M3 S1 needs to be changed to:
# M3 $0 S1 for the plasma torch
# M3 $1 S1 for the scribe
setp plasmac.multi-tool 0
# net plasmac:scribe-arm plasmac.scribe-arm => ***YOUR_SCRIBE_ARMING_OUTPUT***
# net plasmac:scribe-on plasmac.scribe-on => ***YOUR_AIR_SCRIBE_ON_OUTPUT***

It wouldn't be in your original file because you had mode 0. You can just add the line in and put in your 7i96 pin that you connect the signal to.

Sorry I need some more guidance as my head is blowing upYes, that is the correct file.

I have changed the ini file with the mode from 0 to 1
.
I have made the coil with a reed switch in the plasma ground lead and it seems to stop closed when cutting
Q. Is this switch going to trigger the original relay. Or is it going to be connected to another input on the 7i96 ?

net plasmac:arc-voltage-in hm2_7i96.0.encoder.00.velocity => plasmac.arc-voltage-in
net plasmac:float-switch hm2_7i96.0.gpio.003.in => debounce.0.0.in
net plasmac:breakaway hm2_7i96.0.gpio.004.in_not => debounce.0.1.in

# net plasmac:ohmic-enable plasmac.ohmic-enable => {YOUR OHMIC ENABLE PIN}
net plasmac:torch-on => hm2_7i96.0.ssr.00.out-00
Is this the line I need to change net plasmac:torch-on => hm2_7i96.0.ssr.00.out-00
.
Is this correct:-
net plasmac:arc-ok-in hm2_7i96.0.ssr.00.out-00 => plasmac.arc-ok-in
.
You would need to change PlasmaC to mode 1 in the in file and you would need to enable the following in your connections.hal file.
#net plasmac:arc-ok-in ***YOUR_PLASMA_ARC_OK*** => plasmac.arc-ok-in

Add the following line:
net plasmac:arc-ok-in hm2_7i96.0.gpio.nnn.in => plasmac.arc-ok-in

Waiting patiently.......
Well a very big thanks to all that have helped me with this problem Ie. Tom, Rod and the star Phil
.
The reed switch works as Tom predicted. photos.app.goo.gl/btkxisYHNujgkM1N6
The part is about 1mm over size so that could be a kerf param. greater of smaller ?
I think this topic can be marked as solved
.
Edit: Phil will using this method effect the THC ?

That has to be done by you, by editing the original post.I think this topic can be marked as solved

.I am very glad it works, i hate that i can not just jump there and help.
P.S.
Why is there a hole inside a hole ?
Ha. yes the piece was just a test cut and I want to measure the hole. so no reason apart from the extra cut.
Re the over size and under size is that a kerf param?. to change. the gantry travels the correct distance over 1200mm
