QTDragon stop & pause run

Category: Qtvcp

Hello,
I'm using the file pause_pin_2023-09-18.py and I'm getting an error message.
I started LinuxCNC in the terminal with "linuxcnc -v My-Machine.ini" and I get this message:


User command file for pause pin found

[QTvcp.QTVCP.QT_MAKEGUI][ERROR]  No module named 'qtdragon_handler' (qt_makegui.py:361)
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/qtvcp/qt_makegui.py", line 359, in call_user_command_
    exec(compile(open(rcfile, "rb").read(), rcfile, 'exec'),local)
  File "pause_pin.py", line 5, in <module>
    import qtdragon_handler as SELF
ModuleNotFoundError: No module named 'qtdragon_handler'

How can I fix the error?

As far as mesaflash goes, make sure you do a:

sudo make install

or you will end up running the older preinstalled version of mesaflash.

(current mesaflash version is 3.5.13 )

As far as following errors go, they are expected in initial setup
of analog servo systems. For example, you have a 50% chance of
having the initial feedback direction wrong so you get an instant
runaway when the drives are first enabled.

How to refresh the Axis screen after setting offsets G10 L20

Category: AXIS

This turned strange so i fired one of the laptops with 2.8.4 and sure enough it is not in Axis but it is in PlasmaC Axis as cane be seen in the attachment.
This should be included in normal Axis, although rarely needed, it is a good feature to have

PlasmaC uses it, i have it on several machines in daily use, so might be there....
Just checked the 2.10 on this PC, not there either...

Hi npostma,

There shouldn't be any issue using multiple tools in a single g-code file in Fusion360. You create your setup and then separate operations under the setup. Each operation can use a different tool. Just make sure the setup is selected when you post and it will put all the operations in the same file. If you just have a single operation selected then it will just output that single operation in the g-code file.

Yeah I forgot about mesaflash reporting the wrong version.
I dunno why it does that, might be worth raising an issue.
Pcnconf doesn't let you build a config ?
It's been a while since I've actually had to build a config from scratch.

A following error is usually preceded by a latency error, so check that out, also ethernet latency can be an issue as well. Hopefully PCW might chime in.

Righto then, hang the expense I'll order myself a USB blaster as well.

That is were i built mesaflash from, however it only nets version 3.4.6 (unless im doing something wrong)

however, this evening i have discovered that you dont actually need to be able to connect to the card with MesaCT in order to build a config. ive had some positive progress with getting one servo&encoder wired in. the encoder shows movement and the servo blips when trying to turn the machine on before it errors out due to following error.

the tricky thing now, is i cant find the specs for these encoders to verify the PPR.

i would still love to know the answers to the original questions ofcourse, as im sure i may need to sort those errors sooner rather than later

Merging operations NGC files Fusion 360

Category: CAD CAM

Hi community,

Thanks to the help of several members, I’ve been able to upgrade my machine and it’s now working better than ever. So I wanted to give something back.

I mainly use Fusion 360 to create my toolpaths, but I noticed I couldn’t easily use multiple tools within a single G-code file. Fusion360 requires saving each operation as a separate .ngc file. To streamline my workflow, I wrote a small Python script that merges all the generated .ngc files back into one file.

To be clear: I’m still quite inexperienced with CNC (this is just a hobby for me), but I am a software developer—so any feedback or improvements are very welcome! I’m still testing and iterating, but maybe it’s already useful for some of you.

You can find the project here:

don't really remember, maybe 1 minute, but a USB blaster for 5USD is worth it

You can build from source by following the instructions here:

github.com/LinuxCNC/mesaflash

As for the Linuxcnc version I doubt whether 2.1 could be built on a recent linux distro due to python issues.

How to refresh the Axis screen after setting offsets G10 L20

Category: AXIS

This should work for 2.8 and up, notice the hal command at the end for refreshing the Gremlin (plotter).

Not sure where you got that information from but I don't see an 'axisui.refresh' pin:

i did some rework on the mounting for my air cylinders and have been getting stuff gathered and sorted for driving this chuck while i have been working on the clamping needs for soft jaws for this thing. i did some testing to see how good things will center and with out to much effort i looks like things will at least be within .015 off center at the worst 90 degrees from the air cylinders. centering and around .005 off in the line of the two air cylinders. so things look promising so far.

I'm not sure what would realistic since stock tubing is not going to be perfect to begin with but i have one last thing to try to see if i can get things in line better to get as good as i can get and produce repeatable results every time. If i can get within .005 of center all the way around i don't think it's going to get much better than that or at least on a repeatable level.

accurate clamping and centering will open up better options for programming a rotary, so this is my end game. i also think once you add a second chuck that will help quite a bit as well.
