PlasmaC questions new setup

3:rd but still novice in LCNC world

Yes, 3rd and ...... wait, what?

Old fart - slower learner but still the hunger of learning more. Problem is memory

If I need to edit IO in HAL is this to be done in base config?
Does plasmaC read the base HAL every start?

yesterday you were so kind an prepared a gcode file with 0,0,0 down left corner for me but I cannot find that.

How do I invert this?

# --- Float-head---
net float-head<= hm2_7i96.0.gpio.004.in

-not does not work = will not load LCNC

In tecnoplasma HAL
# --- Float-head---
net float-head<= hm2_7i96.0.gpio.004.in

In tecnoplasma-connections HAL
addf debounce.0 servo-thread# --- Float-head---
net float-head<= hm2_7i96.0.gpio.004.in

#***** 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.2.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.004.in => debounce.0.0.in

Terminal
hm2/hm2_7i96.0: registered
sysctl: cannot stat /proc/sys/net/ipv6/conf/eth0/disable_ipv6: Filen eller katalogen finns inte
hm2_eth: ERROR: Failed to execute '/sbin/sysctl -q net.ipv6.conf.eth0.disable_ipv6=1'
twopass: Error in file ./tecnoplasma_connections.hal:
Pin 'hm2_7i96.0.gpio.004.in' was already linked to signal 'float-head<='
Shutting down and cleaning up LinuxCNC...

I can not solve this as is but I made an error connecting the switch as NC and it should have been NO as it is now.

Z works OK = homing correctly and moving Up/Down with keyboard.
Once in plasmaC it started moving in wrong direction if that has to do with NC/NO on the float switch?

Your float head should NOT be connected in tecnoplasma HAL, all plasma connection are done by the Configurator in the tecnoplasma-connections HAL file. It should be something like:

# 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

#***** debounce for the float switch *****
# the lower the delay here the better
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 next line needs to be the joint associated with the Z axis

net plasmac:torch-on => hm2_7i96.0.ssr.00.out-00

# a 1 here allows multiple tools to be used

I had ipv6 disabled but forgot hm2_eth uses it so in /boot/cmdline.txt delete the ipv6.disable=1 off the end.

I made some cable surgery and fixed the float switch to NO >>>> net plasmac:float-switch hm2_7i96.0.gpio.004.in

Now the leds on 7i96 show correct switch that is head down no led

But no longer is the led in plasmaC showing switch status. So I must have messed up something
