Change jog speed while jogging?

When I use an edge probe on my machine I like to be able to control the jog speed while I am actually jogging. The closer to the edge the lower the jogspeed. I have a potentiometer set up to control the feedoverride and the jogspeed override, however for the jogspeed override to take effect I need to stop jogging and then continue.

Is there a way to change the jog-speed while actually jogging?

no
this has been a safety issue and has been rejected
you can hack into the code and compile your own one with all risk to your programming

most behavior is on
C to the position then I steps down YOU know your I so 5mm 1mm .5mm .1mm .05mm .01mm
this is the way to position
Even on a WB06 you can set 6 stepdowns
and you can hack that to a multiply as you can press one key and go
Jogg 2500mm/min 1000mm/min 500mm/min 50mm/min on button press
and on relese you got the .5mm .1mm .05mm .01mm

thats how i use it on plasma to get position on a 5meter table

An MPG is nice for this. Spin it fast to go fast and slow as needed.

Where did you get that idea? How is this a safety issue? Who rejected this?

I haven't confirmed the problem with feedoveride and jogging but it wouldn't surprise me.
Jogging uses separate code for trajectory planning, I'd bet it doesn't check the feedoverride setting except when initiating the move.

Well, I certainly aint going to fiddle with the source code! I thought that somehow the jog-speed could be controlled just like the feedrate. I guess I just have to get used it not being possible.

I've got another question relating to this topic if I may:
There is a pin halui.n.jog.analog thas is supposed to enable jogging with an analog input device such as a joystick. Now I've set this to 100 but absolutely nothing changed regarding the jog behavior of axis 0. Is there some kind of analog-enable that needs to be activated?

changing the value of halui.jogāˆ’speed while joging works in 2.7. I have it connected to the same potentiometer as feed and rapid override.

Thanks fixer for that information. That sounds like the exact setup im trying to achieve!
Would you consider sharing the relevant Hal sections?

OK, so I,ve got this working to the point where I can jog the axis by pressing an external switch and dynamically change the jog-speed by turning a potmeter. I do this by using the Potmeter value and feeding it to halui.jog-speed.
Unfortunately now the keyboard cursor-keys do not work for jogging anymore. Does anybody know how to connect the keyboard-cursor-keys in HAL (gmoccapy)?
Thanks

You can't connect keyboard jogging to HAL.

Keyboard jogging is handled by the GUI (And is an abomination). Best not to use it at all, really.
