Shortcut for homing

I would like to know the short key command for running a homing cycle ($H)
I know I can go to the MDI windows, but I prefer to use a key (f.ex H) in the same way as I use arrows for moving the gantry around
I have search but not find an answer. Hope someone can help

All the best from

No shortcut key, sorry.

Why would you want one? This operation is usually carried out only once per session - at the beginning of operations.

Would building and running macros from your keyboard work for you? There is a very simple keyboard macro program called G-Hotkey, which, I think, would be easy to set up. G-Hotkey, which is free, also works for applications that use directx/direct input, so it will work where other programs like Autohotkey will not (unless AH has been updated since I last tried to use it for a directx game). The basic steps would be to assign to the H key these steps: press M to get to the MDI, enter $H, press Enter/Return.G-Hotkey is gui-driven so you don’t have to do any scripting/programming to get it to work. I can’t guarantee it will work; I haven’t had enough need for macros to try it out on CM myself. At least it’s a start.

I am trying to build i CNC remote (Arcade buttons => I-pac => USB => Computer).

Thanks for input both of you, Think I will give @Boothecus suggestion a try.

Beside homing I can see there is no shurtcut for zeroing. Hope that
G92 X0 Y0 Z0
will do the trick

Kind regards

I’m pretty sure G92 won’t work — it’s disabled unless over-ridden or sent from w/in a file.

Instead, open the Log window, zero things, and note the commands used there — I think it’s the G54 work coordinate system (which is how the system is able to remember zero after re-starting).

I will be interested in your remote. I am thinking about doing the same thing, but I’ve been too busy to get started on it. My plan is to use an Arduino Teensy, a thumb joystick (for x and y jogging), a rotary switch for job speed and a bunch of programmable buttons. I have all the parts. Unfortunately, “motivation” is not covered by Amazon Prime.


There have been some pretty cool remotes worked up, and I enjoy using a Wii Remote when I find occasion to grab one.

Agree it would be nice if we could get all the functions mapped to keys — my ideal layout for a Wii Remote would be:

  • cursor pad used to jog in X-Y
  • A and B used to jog up/down in Z
  • plus (+) and minus (-) used to increase / decrease speed increment used for jogging
  • Home button goes home

Thanks to all of you for help and support.
You have made me go ‘tinkering’ for a while. I believe I will end up with a combination between my i-pac and arcade butoons plus @Boothecus idea with G-Hotkey.

Will let pics and info flow when I have something psysical to show

Another idea I had when I was thinking about this was to include a thin piece of metal (one “leaf” of a thickness feeler gauge) to use for touching off. As I said, I just don’t have the motivation at this time to work on the thing myself.

I have been working on the drawing for my controller and here is a pic of my first mockup. which willl show in public.

Gray circles are arcadebuttons which light up, when pressed.
With this 5 position switch I will select speed for movements:
A red LED will light up for the speed selected. To confirm or get action I will press ‘move’

Please note that my drawing is not scaled or anything. I was thinking of kind of stuff to my control to box - e.g.
a button to turn light on/off in enclosure
og button to turn vacuumcleaner on/off
But I will mount something like this to back off the controlbox and therefore I belive powercords and all other stuff then a USB connector will messed things up

If you have any input whatsoever please let me know. I will make an update in the thread as soon as I have something to new to bring to forum

An alternative to the NO switches for x, y and z might be this a thumb joystick. I bought two to build my own device but the parts didn’t come with any motivation so I haven’t gotten around to it yet. I think it would be good to add some programmable macro buttons. I could use that because I have several repeatable projects that always start at the same location and I have those coordinates written on the wall.
