Issue with Octoprint 1.4.0 or newer - print not starting

[Thomas-74]

Hello,

I'm running a M3D Micro using the M33 Fio plugin. When I start a print, the printer doesn't move and doesn't heat up. In the octoprint support forum, I was told that this is related to a keyword not being supported anymore by Octoprint 1.4.0. or newer: https://community.octoprint.org/t/print-not-starting/16950/3

Here's a log from octoprint:

And here's what's happening in the M33 Fio plugin:

That continues until I abort Octoprint with Strg+C.

The last version of OctoPrint that I fully tested M33 Fio in was version 1.3.5. I doubt that it will fully work in any version of OctoPrint newer than that.

[Thomas-74]

Thank you for that information. Do you plan an update to fix that compatibility issue or is the development stopped?

[donovan6000]

I don't own a Micro 3D printer anymore, so I doubt I'll ever make M33 Fio compatible with any newer versions of OctoPrint.

[Thomas-74]

OK, thanks for telling. So I shall stick to the older version of Octoprint, then.
