Runaway torch THCAD-10 + PlasmaC + Hypertherm 45XP

How fast is your base thread?

The base thread frequency will determine the maximum count rate of the software encoder

At a 1/128 division ratio, the maximum THCAD output frequency will be about 7 KHz
For the software encoder to count this reliably you need an absolute minimum of 14 KHz
(~70 usec) base thread but this assumes 0 jitter. Allowing for jitter, a safer base thread rate
would be about 25 KHz (40 usec)

I've tried F/128 settings and it's giving some hope


PCW - here are settings from INI file and HAL Latency test
BASE_PERIOD = 64000
SERVO_PERIOD = 1000000

That seems usable.
Do you get latency warnings while using LinuxCNC?

Tommylight - no latency warnings now, I used to have latency warnings, but isolcpus fixed the issue.

I still haven't solved the PREVIEW issue reported on the other post .

Again - thank you for all of you for the massive support!

That is due to other languages if i remember correctly, but i think it was already fixed for German and it is not present in English, but again not sure about it.

I was struggling to make THC fully operational via LPT. As I'm starting to do more cuts I'm following your advice and I've just ordered MESA 7i96 card. Now I need to rewire the control box and reinstall OS...
