SOLVED OctoPrint 1.3.4 won't recognise UMO+

[doktormac 0]

I have set up OctoPrint 1.3.4 on a Raspberry Pi. Cam works fine.

I can print from Cura 2.6 to the UMO+ with Firmware 15.04.6.

Changing the USB Cable from Laptop to Raspberry Pi , OctoPrint won't recognize the UMO+.

I read it could have to do with the baudrate - but no idea, where to change…

What is the failure?

How can I print from OctoPrint to UMO+?

Thanks for help!

Regards

Peter

Did you use the "official" OctoPi image, or did you install OctoPrint on an already running Raspberry Pi OS (eg Raspbian)? If the latter, what version of that OS are you using? Have you added the pi user to the dialout group?

In the OctoPrint sidebar, under connection, is there a serial port listed, or is "AUTO" the only option? If you have the default UMO+ firmware, the baudrate should be 250000.

Hi!

Thanks, I had to put baudrate to 250000 (and, made an upgrade from OctoPi…)

That was it!
