Pinout for SB000 missing, no fan is working #64

Open diberben opened 11 months ago

diberben commented 11 months ago

Hi all, after connecting the SB2240 to my Voron Tap with LGX lite, no fans are working. From my printer.cfg:

[fan] pin: EBBCan: PA0

[heater_fan hotend_fan] pin: EBBCan: PA1 heater: extruder heater_temp: 45.0

Temperature reading is nominal (currently 55°C), dashboard indicates Hotend Fan 100%, but vfan1 and vfan2 on SB0000 do not output any voltage. Fan is a Sunon MF40102V2) and is working (checked with lab PSU). Whats wrong?

This may be redundant, but please make sure you have commented out / removed the original [fan] and [heater_fan hotend_fan] sections in all configuration files. Klipper will not warn you if you have these defined twice.

Take care, it seems that you inverted the pin ( but you followed the manual :') ) : https://github.com/bigtreetech/EBB/issues/29

This was it! Thanks Nemernemer! Rescanned .cfg and found one little legacy pin-definition :/ The pinout is still missing, though
