At least it can be used without massive latency like the builtin causes on my Brix J1900.


I’m curious… did you have to disconnect the card inside the computer or was disabling the Sufi enough?

Its a long time ago but I think not installing the driver was sufficient but I removed the supplied Intel Bluetooth/wifi card to be sure. 

Update - 8/11/21

New pc (2007 iMac) to install QTplasmac.

Still working through some coding issues to get the probe/float to work, and then we can start cutting again.

 

To test the float switch all you have to do is move the torch up by hand and watch the screen, the "float" LED should turn on even when machine is disabled.
I think i already mentioned this, but probably the float switch pin is not in HAL where it should be.

Thanks Tommy,
the 'float' led doesn't light up.

I have checked the Hal show and can see it working so know the mechanical side of things is right.

I setup using PnCConf wizard.

Can you share a copy of your HAL file and what it should look like, I have tried to use what was working in PlasmaC Hal file, however haven't got this right yet.

Cheers

Yes i can but it will confuse you even more as all my Plasma configs are hand edited.
I will upload them when i get to the machines.

In your Hal file you should a a line something along the lines of:

net plasmac.float <= your-hal-pin-that-lights-up
 

 

My Hal file
Key lines
85 # --- PROBE-IN ---
86 net float-switch    <=  hm2_7i96.0.gpio.008.in

311 #  ---probe signal---
313 net float-switch     =>  motion.probe-input

334 et plasmac:float-switch-out     db_float.out                =>  plasmac.float-switch

 

313 should be:

net float-switch => db_float.in
 

Error - 316: Pin 'db_float.in' was already linked to signal 'plasmac:float-switch'

Line 38 in Hal file
38 net plasmac:float-switch     => db_float.in

I have tried to copy the old PlasmaC file to patch things. Clearly i know not what commands do. 

Thanks Guys. I'll try and read up a bit more, I probably missed it in the config (most of the details i edited after setup to match what i had with the setup on PlasmaC anyway).

 

Then you need:

net plasmac:float-switch <= hm2_7i96.0.gpio.008.in
