Remember a plasma cutter is a blunt axe, not a surgical scalpel.
Ask yourself is the cut quality adequate for welding and fabrication? It will never be like an accurately machined part.
The plasma primer has some info about cut heights and angularity

Thanks Peter,
So ... <= hm2_7i92.0.7i73.0.2.analogin0, 1, 2 are confirmed
as are both
<= hm2_7i92.0.7i73.0.2.enc0.rawcounts and
<= hm2_7i92.0.7i73.0.2.input-08

but I guess one is processing the data differently from the other.

Typically you use 1X quadrature mode for MPGs (the 7I73 default)

If in doubt about pin names, you can always follow the pin tree in halshow  or do something like:

halcmd show all | grep -i 7i73

(when linuxcnc is running)
 

Next task is Pendant encoder and feedrate pots.

I've a 7i92-7i77-7i73 combination.
From the 7i73 manual, I can use pins,3(IN0),4(IN1) and 5 (IN2) for 0-3.3v analogue inputs.
which I think I can call using
... <= hm2_7i92.0.7i73.0.0.analogin0, 1, 2

Then original Hurco mpg, (5 volt ) pulses can be connected pins 14 (IN8) and 15 (IN9) channels for a and b.
For which I think I need to set the mode
setp hm2_7i92.0.7i73.0.0.nvencmode1 4 (if quadrature scaled)

but then I am unsure how to refer to the pin.
my guesses .
.... <= hm2_7i92.0.7i73.0.2.input-08
... <= hm2_7i92.0.7i73.0.2.enc0.rawcounts

Are they interchangeable, or is only one effective depending on the mode?

As ever indebted to your kind selves.

I was on 2.9.3 and today I updated to 2.9.4
After the update the Jog from the keyboard no longer works.
If I press the buttons with the mouse they work.
In the ini file I have KEYBOARD_JOG=1 enabled
Does anyone know what the problem could be?

The first problem is real time issues with the network interface.

To get a rough idea where things are, can you run these two commands and reply with the results:

sudo chrt 99 ping -i .001 -c 60000 -q 10.10.10.10

This will run for 1 minute and print statistics
(replace 10.10.10.10 with 192.168.1.121 if that's the 7I76Es address)

lspci | grep -i eth

(this should make it possible to determine the PCs Ethernet interface type)

I tried with new consumables because I was thinking about swirling due to a worn nozzle but ithe issue remains the same.
The air pressure/flow is automatically adjusted by the powermax and it’s air supply respects the manufacturer’s recommendations (pressure, flow, water/oil contamination etc…)

Regarding the cutting direction, I let Pronest decide for me but I will try on next cuts.
Do you think compensating the torch inclination could work?
