What is the problem?

Unable to connect. to brand new prusa mk3s+ . Maybe I need to enable something on the prusa?

What did you already try to solve it?

not much. rebooted pi a few times. rebooted printer a few times. hit the connect button a few times. connection keeps failing.

Have you tried running in safe mode?

yes

Did running in safe mode solve the problem?

no

1.7.0. I had been running 1.6.X, and upgraded to 1.7.0 but never tried connecting previously. like i said, just finished building the prusa yesterday. i wonder if i have to enable something on the prusa side I'm running octopi on a raspberry pi 4B. I've tried plugging int bothto the usb3 and usb 2 ports, but no love. I've tried safe mode, i've tried rebooting both the printer and the pi a few times.

My logs don't give much:

Looks like it WAS something in the prusa menu. i had to turn OFF "rasp Pi connection". Who knew?

That is one of the most confusing settings a printer manufacturer has created

I blame the Raspberry Pi organization for not creating a Zero W Plus with a multi-core CPU and two to four times the memory :slight_smile:

Then Prusa's solution of embedding an RPi would be viable.
