qtdragon_hd touchoff and probing issue

Awesome! (re fix to the auto_tool_probe sim for qtdragon)

unfortunately it didn't fix it. But I now have a system I can test installed versions on so can work a little less blindly.

qt_auto_tool_probe uses remap of m6 to add tool probing to tool changes.
It's integrated with Versa probe so you can control a few things such as probe speed.
It uses HAL pins read from Versa for this.
It also uses INI setting for tool change / tool probe location.
With a few changes in the NGC file you could ignore the Versa settings all together.

The rest of Versa probing ie material probing, doesn't need or use remap.

Parameters #5070 and #5063 are for probe results and current coordinates:
linuxcnc.org/docs/2.9/html/gcode/overvie...:overview-parameters

if you need to remap m6 for two different uses you would need to make a custom remap.
(I didn't read the printnc stuff to see what it is doing with M6.)

I'm finally get back to this.  I am working on migrating from LCNC 2.8.4 + QTDragon to LCNC 2.9 + QTDragon_HD.  I am also going to give Versa Probe a try.  Right now, I am just playing with probing and preparing to get my M6 remap going.   To do that I need to write some values to some custom numbered parameters from within Python.  In probe_routines.py to be specific.  How can I update a numbered parameter from within the Python code?

Thanks
John

Parameters can currently only be manipulated in NGC files or remap python code.
Ui python can not directly set or read parameters.

Thanks Chris.

It just occurred to me how that I can get the data I need without storing it in a custom parameter. But before I do that and end up reinventing the wheel. My current workflow is:
Probe the work with a 3D probe:
At each tool change, via my remap, If the tool length in the tool table is > 0 then just use the tool with that offset. If the tool length is 0 then go to the tool setter and measure the tool and use the measured offset.
Is that possible using what already exists in Versa Probe and the Python remap?

Thanks
John

By modifying qt_auto_probe.ngc I think you could do what you want.
tool offset parameters are available in 5401-5409
Some experiments should tell the tale.

Thanks,

I will give it a try.

I took a look at qt_auto_probe.ngc. That looks like the place where I will apply the value at tool change that i saved when I probed the work with my 3D probe.

I save the location of Z minus the length of my probe in a custom parameter 4001-4008 representing G54-G59.2. This would need to happen in probe_routines.py. In 2.8.4 qtdragon this was done in probe_z_minus_wco.ngc. Today I have been trying call a .ngc file to save the value to #4001 using an mdi call from withing probe_down in probe_routines.py but no luck so far.

can you show your code?
