if you still have probe basic installed, would you mind running a test in the simulation? I am running a sim test here and cannot reproduce the error using the on screen probing buttons. i can probe a point in space and immediately jog afterwards using both the keyboard and on screen buttons. so its hard for me to discover why your install is not responding the same. but if you test the sim and the problem does not exist then it would be something in your configuration most likely.

when you say locks out, were you referring to keyboard, on screen buttons, or both?

Yes, the PWM value (from the PID component) should increase as the position
error increases.

Did you check the 5V power?

Are CR23 and CR27 (Yellow LEDs near the center of the card) both fully illuminated?
(these LEDS indicate the analog +16/-12V power supply operation)

The reason I suggest at least 20% extra terminals, is that you will certainly add a pendant, and most likely a 4th axis, but once you lay out your cabinet, it will be full (they always are) so no expension built in means a PITA to add expansion later. Ask me how I know

Furthermore, the Mesa disconnects after approximately 5 minutes with these values. The 1A Ff fuse doesn't blow, but the wire deforms. I suspect that due to increased contact resistance, the voltage at the Mesa is no longer sufficient.

When I move the axis further using the LinuxCNC interface, the value keeps increasing, as if it were the value of the distance traveled... for example, -77... Is that supposed to happen? I'm also only getting 0.35V at the other PWM outputs, both with and without the power amplifier connected.

QtPlasmaC updates - Master (v2.10):
GUI

• align cone_size spinboxs with glcanon allowables

PlasmaC Component

• remove safe_min from THC top limit check in Mode 2
• allow THC up/down outputs in Mode 2 when idle
• fix arc voltage ring buffer off-by-one errors
• general housekeeping

I will definitly check that, when the machine is back together. At the moment i cant power on the machine because most of the wires are disconnected.

-UP/DOWN/ARC_ON LED's on the main screen MUST be usable even while not cutting to check standalone THC's like Proma

Done.

There is some good information in there, thanks.

Ok it is officially January 1 2026 in my area and fusion 360 is still working on my Windows 10 machine.
Will it stay that way through out 2026? Don't know. 

Post from Autodesk forum:Microsoft will end mainstream support for Windows 10 on October 14, 2025. As outlined in our official Autodesk announcement, Fusion will still run on Windows 10 after this date, but:

• Windows 10 will no longer be a supported or validated platform for future Fusion releases.
• Autodesk will not guarantee compatibility, bug fixes, or product support for Fusion on Windows 10 after October 14, 2025.
• Fusion will not support Windows 10 LTS builds beyond this date, as Fusion follows Microsoft’s General Availability Channel.

So F360 will run on W10 for now, but my interpretation is that if there are issues due to F360 updates Autodesk isn't going to fix them.  Eventually F360 will stop working completely with W10, just like it did with W7 & W8 a few years ago.

As I mentioned early in this thread, I've moved to Win11 LTSC in the last month and am happy with it.  No AI, no telemetry, no spyware, no junk, no suprise 'feature' updates.  Can load it with zero MS add-on's.  So far it's been clean and fast.

Not an apologist for MS or Windows, but for those who must remain on Windows like myself, the Enterprise LTSC version seems to be the least objectionable option.

Maybe have a look at this:
askubuntu.com/questions/524384/how-can-i...epending-on-activity

36 bit IN TRUE hm2_7i97.0.pwmgen.00.enable <== x-enable
36 float IN -2.5 hm2_7i97.0.pwmgen.00.value <== x-output
36 s32 RW 1 hm2_7i97.0.pwmgen.00.output-type
36 float RW 10 hm2_7i97.0.pwmgen.00.scale

With these settings you would expect about -2.5V output of analog out 0

Possible reasons to not get about -2.5V

Looking at the wrong pins

output overloaded

5V 7I97T supply low

Damaged 7I97T

Hello Chris, i would really like the jog increment pins qtdragon.jog-linear-increment and qtdragon.jog-angular-increment. But i cannot find them, I'm running LinuxCNC 2.9.7. I have also searching through the master branch of QTDragon-HD, without luck.

How could I get the latest version of QTDragon-HD installed to my LinuxCNC?

wow it works pretty well!

great job

there is some peaking but much less then I expected ... servo period is 250 000ns

I reduced BASE_PERIOD down to  50000 ns and peaking is weaker ... 

Testing at real setup isolated last core is with cold system latency 12.37us
