Getting a MCU 'rpi' error during config.
Im upgrading from hybrid to iDex. Using Manta M8P and CB1.
Adding
[fan]
pin: rpi:gpio79
to printer.cfg seems to fix error.... no errors on start up anyway
my question is, is this the right way to do it?

are you connecting the fans on toolboard or main board?

fluid valve Feb 1, 2025, 5:03 PM

#

both fans are 4 wire 24v connected to ebb42 boards.

#

blue connected to ebb, red/black to main board. correct?

#

the OG
[fan]
pin: rpi:gpio4 is just a sacrificial/virtual pin to be able to controll both parts fans. Maybe this is causing any conflict with the manta... It works on all the others

red black tapped into the 24v supply to the ebb

#

so, looks like you are doing it correctly.

fluid valve red black tapped into the 24v supply to the ebb

that works too

#

yeah i think its because the cb1 doesnt have that pin

mystic cradle Feb 1, 2025, 5:07 PM

#

probably...

fluid valve Feb 1, 2025, 5:07 PM

#

so my addding my bit to the printer config is a legit fix?

mystic cradle Feb 1, 2025, 5:07 PM

#

for now, keep it with the included pin you set up in printer.cfg

fluid valve Feb 1, 2025, 5:07 PM

#

ok. i can control both seperatly in the os
