What is the problem?
Just like the title says;
I've installed the latest Marlin 2.0 bugfix release and use Trinamic TMC2208 stepper drivers witch are controlled via a UART connection.
This makes Octoprint unstable. I had to disable the "EEPROM Marlin editor" plugin to get Octoprint to work at all but still somtimes I have a strange issue.
The issue is that Octoprint receives serial data just fine but it can't send any.
With the plugin disabled Octoprint is mostly usable but a M500 imediate blocks the serial connection.
What did you already try to solve it?
- I used google (and found nothing)
- I switched Pi's (Used the Pi from a different printer) with the same result
- Connected the printer to my PC and used a serial console witch worked fine
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware,
serial.log or output on terminal tab, ...)
