Did you get this sorted? I have an inch mill and am trying to get qtdragon running in inches. I took a quick look at qtdragon_handler.py and reckon I can probably get that working for touch plate but if it has already been solved that would be great.

OK I see 2.0 may have this sorted.

Yes. I have mine working with a 3D probe and a touch plate. Although I haven't used the touch plate since I got the 3D probe working. I'm running QTDragon on LinuxCNC 2.8. At some point I will switch to LCNC 2.9 and QTDragon_HD. I may wait until 2.9 becomes the latest stable version.Did you get this sorted?

I switched to 2.9 because I saw changes on QTDragon in the touchplate area.
It is sort of working but linuxcnc crashes quite a lot and quite a few unhandled errors. Plus the settings page now says inches but I don't believe they are being handled as such. The values are being taken and used with a G21 with no conversion so guess they are still using mm. I am a little surprised the travel distances during touch plate touchoff are hard coded (in mm) I would have thought they could have been setting variables. I love the look and feel of QTDragon. I have gmoccapy on my other cnc mill with an earlier version of linuxcnc and it seems somewhat dated now. Reckon its going to take a lot of tweaking. Luckily I enjoy that.

I'm running QTDragon in 2.8 using inches. In the qtdragon_handler.py I found this line issuing a G21 unconditionally in the touchoff routine..
#ACTION.CALL_MDI("G21 G49")
I commented the above line out and replaced it with the line.below.
ACTION.CALL_MDI("G49") #Cancel Tool Length Compensation
There were also a few other changes I made to allow both inch and mm to be used. I was under the impression that this issue was fixed in QTDragon_HD that is in 2.9 but I could be wrong. I haven't looked at 2.9 yet.
I attached my handler file so that you can compare it to yours.
