[BUG] GCODE button only works with a connected printer in the Octoprint interface about physicalbutton HOT 6 CLOSED

Hi,

I don't think I can do something about this as you cannot send Gcode to the printer when it's not connected to Octoprint. I hand the Gcode commands to Octoprint, which is then responsible to deliver them to the printer.
Or am I not understanding your problem? If no, please attach the octoprint.log file (with debug level enabled for physicalbutton) when you reproduce the bug.

Cheers,

Thanks for this quiek reply!

I interrupt the power supply to the printer via a relay. Is it possible for octoprint to automatically connect to the printer as soon as it has power? octoprint doesn't need the web interface to communicate with the printer, does it?

use case: the printer is in a different room to the computer. I want to change the filament. Switch on the printer, walk to the other room, connect octoprint, walk back, press the button to increase the temperature...isn't there an easier way?

Octoprint does not need the web interface to be open.

Do you use my plugin to trigger the relay? If yes, put a connect action into the activity list behind the output activity.
If not, i'd say that you could try to place a connect activity just in front of the gcode.

Maybe the gcode activity has to be delayed until the printer has fully connected. Then you could (as a workaround) put a synchronous output activity after the connect activity and select a pin of the raspi you are not using. You have to set the time to a bit more than start time of the printer and connect time.

Or you add a single button that just handles connecting to the printer

Thanks for your hints!!

I'm trying to send the "connect" command 9 seconds after the printer relay closes. unfortunately this doesn't work as expected:

Yes, for the fake delay to work you have to specify a gpio pin that you are not using on your board. In my code the output activity is ignored when gpio is set to none.
But it would definitely make sense for me to add a delay activity for this use case. I bet there are other cases where this could be useful.
