Keyboard shortcut rempaping

I've been doing a bunch of machining on my freshly built mill running QTDragonHD and there's one thing that is absolutely throwing me off. I have a ton of experience running a Tormach on Path Pilot so I have established muscle memory for smacking the space bar to pause (feed hold) when proofing new code. QTDragonHD doesn't appear to have any shortcuts mapped to the space bar when a program is running.

Is it possible to remap the space bar to be pause (feed hold) when running programs?

Thanks!

Which version of linuxcnc are you using?

I'm running version 2.9.3

Try this.
in your config folder add folders qtvcp/screens/qtdragon_hd

in the qtdragon_hd folder add this file, name it qtdragon_hd_handler.py

It doesn't seem to be working. Do I need to call that python file somewhere?

If you run linuxcnc from a terminal, do you see this text?
'Custom subclassed handler loaded for spacebar pause'

sometimes it's a focus problem, try pressing the 'G54' or 'ABS' button (after the program is started.). If that works I will look into why you need to do that.

Thanks for the response. I am getting the line you asked about in the terminal. When I just tried using the space bar pause, it worked in all but one instance. I think you're right, it's a focus issue. In one instance, I had clicked the coolant button and then hit the space bar and the program failed to pause, but I was unable to replicate the behavior in the short session I had to test it this evening. I'll follow up if I'm able to reproduce the failure to pause.

But anyways, thanks for the help with this! I hadn't realized how much I use this feature until I didn't have it. When the tool is plunging rapidly, it's really nice being able to reflexively pause everything to check positions and the distance to go.

I have confirmed, there is a focus issue. I need to click G54 or ABS or similar to move focus before the space bar works. That caused one slightly panicky moment when I hit it and nothing happened. (Fortunately, the code was right so it was fine, I just got scared for a moment.) Is there a way to set focus on cycle start or eliminate the need to move focus?
