My QTDragon issues

Hi
Rather than continuing to hijack another thread I thought I would start my own

I love the look of QT Dragon and want to use it on my CNC mill (A early version of the BF20 by Luxcut).

I had it working this morning in the office with no startup errors and my custom hals. Moved it into the workshop and hooked it up to the mill and the VCPWindow error came back along with a new one.

For some stange reason the QTDragon ui and handler files that I had copied into my config dir had disappeared and the bookmark to the /usr/share/qtvcp/screens dir had gone too. weird!

Anyway, I copied the 2 files back to the config dir and the VCPwindow error is now gone again.But...

Now when I start the machine and hit Home All the machine moves a little and then I get the following error
"Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/qtvcp/widgets/basic_probe.py", line 214, in send_error
self.proc.writeData(message)
AttributeError: 'BasicProbe' object has no attribute 'proc'"

I attach an archive of my Config folder in the hope that someone (Chris?) can help me solve this issue.

The machine works fine using a standard Axis setup

Cheers

What version of linuxcnc are you using and how did you get it?

also if you didn't modify the .ui file (I thought you did in the other thread, when you said custom qtDragon) then there is not need to copy the .ui and handler files into your config.
In this way you get the most up to date files with bug fixes included. Only if you are customizing qtDragon would you want to copy the ui/handler files over.

Hi Chris

uname -a returns
4.16.12-rt5-kona-rt #1 SMP PREEMPT RT Fri Jun 8 10:39:47 JST 2018 x86_64 x86_64 x86_64 GNU/Linux

Linuxcnc is 2.8.0-pre1-5634-gfc53605ea

It is Mint 19.1 that has been updated as per the instructions found here.

So if I delete the ui and handler files it should be OK?

Thanks again
Bruce (I am going to get this Linux thing sorted!)

Deleting the files should work. I just wonder if the files are old versions.

Hi Chris

I still get this error after Home All gives a short Z move and then the error

Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/qtvcp/widgets/basic_probe.py", line 214, in send_error
self.proc.writeData(message)
AttributeError: 'BasicProbe' object has no attribute 'proc'

OK fixed the basic_probe error but still can't home

Running from terminal I get this error

[QtDesigner.QTVCP.QT_ACTION][INFO] Homing Joint: -1 (qt_action.py:90)
joint 2 following error
emc/task/taskintf.cc 942: Error on joint 2, command number 80

Cheers

FIXED IT

Base period was different between the towo configs

Set the base period in QT Dragon to 60000 (same as in Axis) and the machine now homes

WOOHOO!!!

Thank you for the update - wow I'm not sure I would have suggested that. I wonder how that is related.

anyways excellent!

Would be nice if you shared how you fixed that error
