PlasmaC questions new setup

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?

You need to edit the ini and HAL that PlasmaC created.

The base ini and base HAL are only kept as a backup in case, PlasmaC never reads them.

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

forum.linuxcnc.org/plasmac/39179-raspber...mac?start=120#171283

How do I invert this?

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

-not does not work = will not load LCNC

It should still load but the float led would be on all the time.

I think it is in_not

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

hm2_eth: ERROR: Failed to execute '/sbin/sysctl -q net.ipv6.conf.eth0.disable_ipv6=1'

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:

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

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
