MPG Jog Pendant Module Proposal about 6-pack_cnc_controller HOT 8 OPEN

That would be a great if this or similar could be integrated, I wanted to ask this too.
Yes probably needs a expander but the software work will be more challenging i guess.

It looks like the easiest solution might be adding a CH55x chip to handle the USB host functions..

It's good to know that is an option - but anyone who has ever dealt with programming USB devices might take issue with the word "easiest".

Been there.. Done that.. [Good thing I was already nuts before I started..]

ESP32 KE32-WROVER-C10 + GY521 with USB HID over Blueooth.. Enumerates as a joystick..

[Dont ask me to open the can.. Suffice it to say that it looks like R2D2 did a Jackson Pollock..]

The Contour ShuttleXpress might be a good option with a USB Host module.

LinuxCNC has a implementation which would save any reverse engineering:

fixing the jog cancel race condition would be needed first. I believe a much more complete jogging implementation was planned but it couldn't be fit into OG grbl. Maybe the underlying jogging implementation should be fixed first?

from 6-pack_cnc_controller.

Please include references to that race condition.

there are quite a few threads on the topic, here are a few.

gnea/grbl#837

gnea/grbl#734

here is an attempted fix: grblHAL seems to have this fixed and added a few features to support MPG
