Hello Everyone,

I am trying to setup hand wheel jog function to do program inching, is it possible to take control of program movement on hand wheel ?

What it will do is when i start program run, machine will check if handhweel mode is on or off, if its on then user will rotate handwheel and machine will continue program as per handwheel rotation, if user stops rotation program will hold and move further if handwheel is rotated. and if program is okay user will continue with program cycle and so on ...

Not as a built-in behaviour, as far as I know.

But I think you could arrange to do it by manipulating the motion.adaptive-feed pin.

Send the handwheel _velocity_ to the adaptive feed pin in handwheel mode.

You can even go backwards.

Hello Andy,


I tried to add below thread in my machine hal file ... it was throwing error "Scale is already linked to xhc wireless hal file"
I commented it for test, but MPG is not working now ....i'm sure i'm doing something very dumb :(

You might need to add a second scale component.

What is the _exact_ error message?

"Scale" already exists.

You need to loadrt scale in only one place, with the number that you need.

So remove the "loadrt scale" from xhc-whb04b-6.hal, and have
"loadrt scale count=2" in the new (earlier in the sequence) HAL file.

Then use scale.1 in the new stuff, and leave scale.0 in the xhc HAL file.

You need to uncomment line 24.
