I’m confused. I thought that when I started carbide motion. After connecting to the cutter and going to the jog tab that the first thing that happened was a homing sequence. After the homing sequence I expected the position to be X-5 Y-5 and Z -5. But when I do this my positioning says that it is X300 Y300 Z30. It seems that the home position is distance from the workspace X0 Y0 Z0. I did a test and moved the router to x-300 Y-300 Z-30 then zeroed all. After a homing sequence the home position was X300 Y300 Z30. This is true even after turning off the CNC and restarting carbide motion.
Is this normal? Is the home position always the reverse of the current XY position?
Hi @rac8006,
I’m not sure I followed the details of your test, but what you should see is:
- when display is toggled to machine coordinates (clicking on the title label above the positions in CM), you get negative values which are offsets from where the limit switches physically trigger (hence the -5, -5, -5 after homing, due to the pull-off movement that GRBL does after triggering each switch). Don’t you get those machine coordinate values right after homing ?
- when display is toggle to workspace coordinates, the values are relative to wherever you last set your zeroes. And zeroes are persistent across machine power cycles and stopping/re-launching CM, so until you set zeroes to a new location, the workspace coordinates will always be the same for the same physical location

Thanks for the quick response. I never knew about clicking on the title would switch between machine and work position. In fact before clicking it only says position. But after clicking it show machine or work position.
Are there any other hidden things to click in carbide motion?
No I don’t get the machine coordinates after homing. That is why I did the test.
Not that I know of, but I may not have discovered them yet 
I meant, if you just initialize the machine, and then click on the position label, what machine coordinates values are displayed at that point ?
Yes. After I initialize and home the machine. Then click on the title I get the machine coordinates of X-5 Y-5 Z -5.
Again thanks for the quick response.

I found another clickable area in carbide motion. If you click on the no file loaded it will open a window. If you right click on the no file loaded or the file name it brings up a window with back forward reload options. The back and forward are grayed out. Clicking on the reload will reload the current file. If you right click on a loaded file name it opens a window with the gcode of the current file listed, with the option to copy to the clipboard. Not sure where these features would be used.
The latter feature is used to allow for decrypting of .egc files from MeshCAM.
How would that work?
One would license MeshCAM with the Carbide 3D Nomad license, generate G-Code from it, load that into Carbide Motion while connected to a Nomad, then one could access the decrypted G-Code to run it through a previewer or other thing which required the text.
