Print starting on and receive gcode file, but not start print

[BeppeTemp]

What were you doing?

Initial situation: Octoprint server tuned on (indipendente from PSU Control), Printer turned off (controlled from PSU Control, with HomeAssistant Plugin)

1. Press "Upload and Print" on Prusa Slicer
2. PSU Control start printer and wait 10 second (my post on delay setting)
3. Octoprint connect to printer and receive gcode file

How I could see in different issues and posts on octoprint forum, the problem seems is related to an ulterior delay, necessary but not implemented.

In my opinion are necessary two delaies:

1. For printer connection: after the printed is turned on I waiy tot seconds before tell to octoprint to connect
2. For gcode post: after the printer is connected i wait tot seconds (or also milliseconds) before post file, in this way it should start to printing without issues.

What did you expect to happen?

After I press upload and print on Prusa Slicer, Octoprint turn on printer, wait "post delay time" (set to 10) receive the gcode file and start the print.

What happened instead?

After I press upload and print on Prusa Slicer, Octoprint turn on printer, wait "post delay time" (set to 10) receive the gcode file but don't start the print.

Hi Beppe,

It looks like Prusa might be slower to initiate, can you try a 60 or 120 second delay to see?

Is the printer on AMC0?

What is AMC0 ?

I tried with 120 seconds but nothing, simply when I press "upload and print" the print turn off after 120 seconds, after that the gcode is uploaded but print not start
