Set Ready Automatically after print

Hi All,

I'm guessing the answer is "no" but here goes:

Is there a way to "Set Ready" a printer automatically after completing print?
We have a bed cleaner mod on one of our old MK3s that was working well on Octoprint but it would be great to have all of our printers on PrusaConnect.

Thanks for your help.

Haven't tried it, but the M72 gcode is a possibility. 

From  Prusa firmware-specific G-code commands :

M72 - Set/get Printer State
Without any parameter get printer state.

0 = NotReady Used by PrusaConnect

1 = IsReady Used by PrusaConnect

2 = Idle

3 = SD printing finished

4 = Host printing finished

5 = SD printing

6 = Host printing

Usage

M72 [ S ]

Parameters

Snnn - Set printer state 0 = not_ready, 1 = ready

RE:

add:

M72 1

in the very end as new line.
You can also just force add it to the generated gcode.

See my GitHub and printables.com for some 3d stuff that you may like.

 I just tried sending a short file ending with M72 1 (also tried M72 S1) through Octoprint and got the response 'Unknown command: "M72 1"'

 

G28 ; home

M72 1

Good find, @_kaszpir_, M1200 does the trick...

Thanks all for your contributions so far

I have tried both of these, no luck on my end. I also believe the correct syntax would be M72 S1, which does not work for me either.

Not sure whether the hackerboard works with an MK3S, but an input on a hackerboard (triggered by the bed cleaner?) could trigger an M1200. In my testing PrusaConnect responds quickly and changes to 'Ready'.
