I’ve been using it for quite awhile and I definitely like it over v2. That’s not a universal opinion though. Technically, the project from which the FluidNC fork comes from just went from alpha to beta. (Which reminds me that I need to go back and see if my extensions are formatted correctly in the latest version.) So, it’s still a work in progress but I’m not sure how much risk there is. WebUI v2 is still the official V1 recommendation.
I agree with Britt in that you should back up all the files on Flash before upgrading. If it doesn’t work out, you can just swap the files back to v2 and be back where you left off.
I’m not quite sure what you are looking for here. This is the jog panel built into WebUI v3 (with my dark theme).
This can be setup to control via a keyboard or other controller but you’re not going to get true joystick control. I did set it up (but no longer use it) to use a bluetooth game controller.
The jog controller I use within the WebUI is the touch/mouse jog joystick extension that I created which does have separate X/Y/Z jog modes.
What this thread has really become is for the wireless pendant that I created which does have a physical joystick with separate X/Y/Z jog modes much like my extension. That’s independent of the WebUI.
No, I would just create a new topic.
