OctoPrint  

Re: OctoPrint

Installed Octopi on a PI 2 model B. I can bring up the web interface but when I try to connect it will not connect to the MK3. Any suggestions what can be wrong? When it is trying to connect the LCD on the MK3 changes and the fans come on.

What are you connection settings?

Re: OctoPrint

My experience has been that having the baud rate at auto causes issues, that being said ensure your baud rate is 115200...

Re: OctoPrint

Are you using a fresh OctoPrint image or the PrusaPrint OctoPrint image? If you're using the PrusaPrint image and have the Pi connected via USB you will get boot loops because the default connection setting is set for serial, not USB.

Re: OctoPrint

Turn off RPI from the Prusa menu or it won't connect via USB.

Menu->Settings->RPI Port

Set it to Off.

Are you using a skirt or brim that falls outside the print area?

This is expected with the default Octoprint settings. It's because the purge/priming line prints outside the defined print volume. You can just disable this check in Octoprint by going to Settings > Features and un-checking Enable model size detection and warn if model exceeds print bed.

Re: OctoPrint

A better fix is checking "Custom bounding box" in your Printer Profile under "Print bed & build volume" and setting the Y min to -3 for the purge line.

I saw that but was not sure what it was. I should have tried it.

I originally tried that and still got bounding box errors so just gave up and used the hammer solution of flipping off the check. S3D ensures my stuff is within the bed bounding box already, I don't need two checks.
