Part Cooling Fan not working BTT Octopus MAX EZ - New VC4 Build
Hi, I have managed to get the fan working by connecting the 12v to the MFAN port. As soon as the printer powers on the fan spins at 100% so it's getting the 12v it needs. I am guessing the 4 2pin VFAN ports have an issue with the 12v rail and the MFAN must by using a different 12v rail. Looks like it's a faulty Board... Now just need to get it replaced by BTT.

Part Cooling Fan not working BTT Octopus MAX EZ - New VC4 Build
I've not had the chance to test this today but hopefully I'll be able to tomorrow. I can't say I remember the LED on the 12v rail going out but that would make sense. How can you tell if the eFuse blows? You say power cycling resets this but I've never been able to get the 4028 to spin.
When testing the 12v power I still disconnect the Fan at the molex connector enable the fan in mainsail and then test the pins with a multimeter?

Will you only get 12v to the fan (Molex connector) when you turn the Fan on via the Mainsail GUI??

Im sure its the Digital PWM 2pin on the Toolboard. I can't check as the printer is at my work and I am home right now. I wasn't expecting anyone to get back to me this quickly!! lol.

Part Cooling Fan not working BTT Octopus MAX EZ - New VC4 Build
Yep all 3 are lit, the 12v, 5+ and 3,3, but the 3.3 is red not green. I followed the standard octopus setup which uses PA0 on the toolboard for the PWM and then I have 12v running back to the Octopus which I have plugged into FAN0. What I have noticed is that there is a Green light on next to the 12v jumper, but when I increase the Fan speed on Mainsail the the light dims and turns off at 100%. Do I check the 12v on the 2 pin FAN port with the Multimeter??

Orbiter 2.0 Filamentsensor config for Ratrig
Hi, I have the EBB42 1.2version which uses the same pins PB3 and PB4 but can I ask why you need the ^ pull up? The original OrbiterSensor.cfg used ! to reverse to direction???. I had the same issue with multiple unloads plus when restarting the firmware it would immediately heat the extruder and attempt an unload.

Bed Mesh Just Keeps Getting Worse
Hi, I had this same issue. I ended up putting a micro shim on the Aluminium block where the high point on your heightmap show (Yours looks roughly in the middle and then went from there. I guess I had a slightly bent runner, even though I made sure all the Alu blocks were the same height and tightened the same.
