Gmoccapy with jog encoder was created by RotarySMP
I have my MPG connected similar in this example:
gnipsel.com/linuxcnc/hardware/mpg.html
... but with both joints and axis connections and enabled.
The whole signal change works in HALSHOW, with encoder movement changing all the counts through to those axis/joint pins, but no motion. The appropriate axis.x.jog-enable (or axis.z.jog-enable) are both connected and working, but no motion happens. I have done a fair bit of searching but find no reference to Gmoccapy specific pins or settings I need for this to work.
It make no difference whether the axis is homed or not. No motion.
I have attached the postgui HAL. Appreciate some assistance here. Thanks.

Mark, there is a step by step guide in my build (for a 7i76e)
forum.linuxcnc.org/show-your-stuff/32029...build?start=20#85279
Hope it helps.

Hi Rod,
Thanks, but your HAL also ends with the encoder counts being netted to axis.[].jog-counts, which is what I also have. The encoder pulses are also working through to that point. That axis.[].jog-counts changes as I turn the encoder wheel. There is also an axis enabled, but nothing moves.

I am not at home, but out off memory:
- Did you set a jog scale / jog-increment?
I do not know the exact Hal pin name, but I remeber, when I added my first jog-wheel to my machine, about 15 years ago, I had exactly the problem you explained, due to not having set a jog increment with "setp axis-x-jog-increment 0.05" (something similar)

Yes, norbert is reinforcing what PCW has said earlier and is what is missing from your config compared with mine.

Please find attached my config for my pendant based on a 7i73 connected to a 7i76e, My pendant does contain Jog increment selector, Axis selector an 100 ppr MPG and a security button, that mus be held pushed as long as the control is used.
This config may help as start point.
Or try just to add to your config something like:
setp joint.0.jog-scale 0.05
setp joint.1.jog-scale 0.05
setp joint.2.jog-scale 0.05
setp axis.x.jog-scale 0.05
setp axis.y.jog-scale 0.05
setp axis.z.jog-scale 0.05
the 0.05 is machine units per count!

Thanks Rod and Norbert, I think my Gedenkfehler was I thought you have the external increment switch control the GUI buttons, and then the machine follows that.
I did get it working once Rod convinced me to ignore the GUI for this. Afterwards I also added a second set of nets so the one screen GUI follows along with what the phsical switches are doing.
Here is the current HAL:
forum.linuxcnc.org/media/kunena/attachments/2917/mpg.hal
I also now realise that I don't need the "Continuous" jog selection on the MPG. That is only really used with button jogging isnt it?

Great. You answered my question I asked on your video post. Yes continuous is handy on the screen but not used with a MPG. Just wind harder!

Well you could pretend it was an Ugly 0 for off not a C and set it up so the jogs were disabled....
C = disabled sounds good!
C = disabled sounds good!
