been using this cheap one from Wish.com for a while now works great

I use this one " https://www.amazon.com/Alcey-Wireless-Multi-Function-Keyboard-Receiver/dp/B0779MRQTL "
The arrows control X and Y, page up and down controls Z. Depending on your sender the jog speed can be controlled by the + and - or the numbers.

I using this one similar to Hooby’s.

Not exactly a keyboard but I bought a cheap handwheel and used an arduino leonardo which can emulate a keyboard. Works pretty well with carbide motion (it throws away keystrokes so it isnt perfect). I plan on putting a atmega32u4 pro .micro inside the case and then a usb connector on the end.
If anyone’s interested I’ll post the code. It’s pretty simple.

Oh my, THIS is what I have been looking for. I have tried the pendant/bluetooth keypad thing, but somehow it feels weird to me to push buttons repeatedly to jog the machine. That box with the selection knobs and handwheel looks PERFECT to me. I would love if you shared info about the arduino part but mostly about what the design of that box…

A similar thing, but commercial, would be the Contour Design ShuttleXpress — unfortunately, it didn’t work with Macromedia Freehand, so I let my son have it.
It is supported in bCNC, and I believe CNCjs.

Here is the link to the one I purchased:
Any Atmega32u4 with enough I/O pins will work but the smaller micro form factors will fit inside the case and you can just rewire the switches with short wires soldered to the controller.
I’ll upload the code to github and see if I can hack together a quick schematic showing how I wired it up.
For the x1 x10 x100 I just output 1, 2, 3 to select the jog resolution. And depending on the x, y, z setting I output arrows or , .
It only enables the keyboard when you hold the switch on the side. I think I turn on the led when you press the button. Didn’t do anything with the estop yet… suggestions? Feed hold? Actually wire to the estop functionality of the shapeoko controller?

Fantastic, I thought you had designed that sleak box, but even better that I can just buy it on banggood.
Obviously still interested in getting the arduino code & circuit diagram when you have time.
Wiring the estop button to feed hold would be my preference, I already have a separate estop that removes all power from everything (as an estop should 
)

I’m all about saving time wherever I can… so if it’s already made…
Like the new bit setter. I was going to make one using one of the precision limit switches linked in another thread but now that there’s a ready made one that’s one fewer thing I need to make for myself
I’d love to add some more buttons for things like zero axis but need carbide motion to provide a shortcut. I keep meaning to switch gcode sender but I keep defaulting to motion for the most part.

Just placed the banggood order for that pendant, and I have a bunch of arduino pro micro laying around already. Thank you for the inspiration.
The BitSetter is awesome, you won’t be disappointed.
I don’t mean to draw you away from Carbide Motion, but once you get a taste of e.g. CNCjs instead, you will likely be hooked, I know I was.

code is here. it’s pretty rough. wasn’t really meant for public viewing…

Thank you Norm, appreciated. Don’t worry I too have my fair share of “not meant for public viewing” code that I ended up putting up on github anyway
I’m excited to tinker with this in a couple of weeks when my banggood order arrives. I wonder if there will be an easy way to not only jog, but jog faster & coarser OR slower & finer depending on how fast one turns the handwheel (to not even have to turn that x1/x10/x100 selector). That would be neat.

Good idea.
It should be relatively easy to estimate the current velocity of the handwheel and switch speeds when it passes some predefined speeds.
May need some sort of filter or other technique to smooth the incoming data. This is an interesting read but likely overkill…

Rather than keystrokes it would be better to use the builtin jogging functionality in grbl. Does cncjs have builtin pendant support?
I use this controller with my Tormach 1100 CNC mill. Would be nice if someone could figure out how to adapt this to the SO3. I would not have a clue if it’s possible. 
PS Thanks for all the previous replies !

@TOOLZ I’m sure you can adapt it to be used on the SO3. You just need to capture its keystrokes output, write a small conversion code to match that of CM.
Hi,
Thanks for the reply, but I would not have the slightest idea how to do what you referred to. 
Works great on the Tormach,though.

That is a rebadged Contour Design ShuttleXpress — if you download their software for it you can change the buttons used — just remap to some which match the ones CM uses per:
