How to select qtdragon_hd?

@cmorley

Looks like I'm running Linuxcnc 2.8.2. Do I need to upgrade to 2.9 to get access to qtdragon_hd?

OK! So upgrading to linuxcnc 2.9 allowed me to select the qtdragon_hd screen. This youtube video was helpful for doing the upgrade .

Now I need to figure out how to select dark mode.

Excellent! press f12 - it brings up the stylesheet selector

yes you are not out of estop/machine on/homed - ,most keys will be grayed out

@cmorley thanks for all your help so far.

I'm seeing some weird behavior when trying to set up my touch plate. Here's the procedure I'm following:

• Measure the touch plate height with calipers and enter it under SETTINGS > TOUCH PLATE HEIGHT (it's 19.12mm)
• Connect alligator clip to bit and put touch plate under the bit within 20mm
• Press TOUCH PLATE button
• The Z axis moves down until the bit contacts the touch plate, then backs off slightly

At this point I expected that the Z coordinate would be set to the height of the touch plate + the back off distance, but it doesn't seem to be doing that. Any idea what's going on here? What script is this button referencing so I can do more debug?

Also, what is the WORKPIECE HEIGHT field in the OFFSETS section used for?

First off, I'll disclose that I didn't make qtdragon so I don't always know perfectly the intentions of behavior.
Saying that - My understanding is after probing, the G54 Z setting should set zero at the bottom of the touch plate.
(so yes just as you thought)

workpiece height is used with sensor height when using a tool height sensor probe.

You can look at the python code here:
github.com/LinuxCNC/linuxcnc/blob/ca4317...n_hd_handler.py#L904

(I do see some problems if using imperial mode with probing)

I do see an apparent error with probing...
line 923 is not right - that is the lift up move to reprobe - but it returns without reprobing.
It would leave the machine at 4mm above the last probe - which is pretty close to what your image shows.

I have pushed a fix for this. HD now uses the same routine as qtdragon and should work properly (and in metric or imperial)

In case you are still interested, the probe routine is here:
