My ini and hal files look like this (this is the latest version of Linuxcnc - 2.9.2)

I added to the ini file but have not changed the hal file yet (I can't see where to change it)

Great. I tested it and everything works fine. Thanks

One more thing needs to be fixed and qtdragon will be completely usable...

Repeating a post from a month ago:

The 13 ms ping delay is not caused by a power issue (the 7I92 cannot
restart in 13 ms, if it loses power it will take about 1 second to recover),
The delay is most likely caused by some power management running on the host PC.
If this cannot be discovered and changed on the host PC it may be that that
PC is not suitable for real time use.

Furh die stepgen feedback das muss 1000 sein, for die encoder feedback sool mit 30 or 50 einfangen.

That 13.566 is really bad, but no idea why and what is causing it.
Did you try to use a USB-LAN adapter?

Edit, removed info about power supply as it is not relevant to this case.

Sorry for maybe repeating stuff, but we read everything on this forum, so it is hard to keep exact track of info.

Simplified:
- logic level low on base (via a resistor): Transistor is "off" and current does not flow from C to E. "The switch is open"
- logic level high on base (via a resistor): Transistor is "on" and current flows from C to E. "The switch is closed"

That is correct and nicely explained, thank you.
And the base of the transistor does need a resistor, something like 100-470 OHm should do just fine, otherwise the base will draw to much current for the PWM output and most probably will not work at all without it.

Thanks Tommy... I'll give it a try.

Nice idea, and if it ends up in the 20-30$ range with cheap drives, might just be good to have some.
Using those small drives with good Nema23 motors and some reduction can move some pretty hefty machines, any plasma machine with about 20-25Kg gantry and a motor on each side should still be very usable and safely do 10m/m moves, should also be enough for most desktop mills and lathes, so a very good starting point.
BTW, those thinking of using TMC drives with stealth chop and spread cycle case angular misalignment or something like that, so might not be the best choice for mills and lathes if those features are enabled (they can be disabled), should be ok for plasma.

... some background information is required.
I learn with background information and it's always good for my brain ;o)

1. what computer hardware are you using?
We have already discussed the hardware in great detail in this thread.
Please see my post ...
forum.linuxcnc.org/39-pncconf/52373-pncc...7i76?start=30#298972
... Of course, Debian/LinuxCNC is now installed instead of Linux Mint.

2. what is the result of the command
cat /proc/cmdline

The result is ...
cnc@cnc:~$ cat /proc/cmdline

3. what is the result of the following commands?

4. have you disabled all power management options in the BIOS?
Are Hyperthreading and AMT (if available) disabled?

I can't really answer that as this topic has not been dealt with further in the thread either. We got stuck on the disassembly of the PC at the time.
I disassembled the Barbone PC, applied new thermal paste and made modifications that significantly improved the cooling. After that, the issue remained unaddressed. As I don't know the terms and the effects in the BIOS, I don't screw around without the support of cracks ;o)
forum.linuxcnc.org/39-pncconf/52373-pncc...7i76?start=10#298822

Good point, I have already started wondering about adding a weight to tension the wire, which would enable tapered cuts. So I am going to try Tommy's settings now

Dragon loading progressbar should be fixed now.

[DISPLAY]
GRAPHICAL_MAX_FILE_SIZE = -1

Should allow maximize usage of  the memory for graphical display.
or set it to any integer MB of system memory (default would be 20 MB)
Should work with Qtvcp/GMoccapy/AXIS

Pushed to master

Gentlemen, did you realise that from my photo on page 9?

Yes.

I had those Fujitsu, 4 versions of them, all worked perfectly latency wise, so
-disable hyperthreading
-disable TPM
-disable virtualization
-disable power savings, all
-disable turbo
Not sure what else, it was a few years back, but try those first.
Fujitsu uses very good thermal compound so if the processor has not been removed, it should be OK.

Very little difference between having 2 axis/4joints and having 4 axis/4joints as far as editing goes, so i decided to do the 4 version as it leaves the possibility of doing plane wings !

Voltage to low = torch goes up
voltage to high = torch goes down.
