Old POLAR3D Printer

What is the problem?

So my school recently gave up an old POLAR3D printer that I am trying to use with Octoprint. I switched out the raspberry pi in it to a pi4 and installed octoprint. In the Octoprint interface, I can control all axes fine, but I can't extrude for some reason. Even with a file sliced from Cura the printer will move but won't extrude. Any ideas?

What did you do to try and solve it?

Research

Have you tried running in safe mode?

Yes

Did running in safe mode solve the problem?

No

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Hi :tentacle:

Please enable the serial.log (click on the link for help)
It tells us what happened and how the printer responded to the extrude commands.

Just test the usual things - move the axis, heat it up, extrude - and upload a new systeminfo bundle

You have to enable the serial.log first, it is not captured automatically and your log is empty.
