So, this may be a stupid question but I can’t seem to find the answer (the search turned up no results and the Carbide Motion online documentation appears to be for CM v4)…
I have everything updated to Carbide Motion v5.21 with grbl v1.1f (coming from CM v3.68 with grbl 0.9), on Windows10 and I don’t see a way to initiate the homing cycle after the machine has initialized and gone through that process at CM startup…
If I were to run a job and somehow lose a step or two (due to operator mis-judgement), how would I re-home the machine without restarting Carbide Motion?
Version 3 had a dedicated onscreen button for this, but I haven’t seen anything like that in the new interface. Also, the documentation states that you can directly input coordinate values somewhere, but I haven’t discovered where that would happen yet (and I think the documentation/wiki is geared towards v4), not that that would solve my problem of manually initiating the homing cycle…
Go to the MDI and send
EDIT (not $$) to initiate homing.
Ok, diving into the grbl v1.1 MDI commands has yielded the “$H” command for the homing cycle. Definitely not as accessible as a dedicated interface button on the Jog page, but at least now I know how to manually initiate the homing cycle if needed…
I would still like to know where I can input direct coordinates for jogging the machine to a location, as mentioned here:
- Main screen
- L — log window
- M for an “MDI” window which allows manually interacting w/ Grbl.
- Arrow keys jog in the X/Y plane
- ./, jog the Z-axis, +/- or <> or page up/down
- 1–5 — speed control 1 = Jog Fast thru 5 = jog 0.01 mm
- Homing / setting machine position / offset
note that the fields displaying machine coordinates are editable! and one may directly type into them.
Neither ‘Machine Position’ nor ‘Work Position’ allows for the displayed coordinates to be edited…
Is jogging to a specified direct-input coordinate possible (outside of running g-code)?
I tried this ("$$") and I can’t tell if it did anything other than output the machine settings to the log. But “$H” did work for initiating the ‘homing cycle’, I still miss the dedicated button on the rapid positioning tab…
Mistyped — $H is correct. $$ sends settings.
Yes, if using the MDI does not count as “running G-code” ?
You can send for example:
G53 G0 X-100 Y-100 Z-5
to go to absolute machine coordinates (-100mm, -100mm, -5mm) from homing position.
This is exactly what I was looking for, thanks @Julien!
Quick question: Do I press ‘send’ after the G21 line and G90 line, or after all of the lines are input (using Carbide Motion as the controller)?
Actually you can put them all on a single line and hit send once, it will work
G21 G90 G53 G0 X-100 Y-100 Z-5
Thanks man, you are awesome!!
I really mean that. I see you and @WillAdams help so many people on this board, please know that you are very much appreciated!
