Issues with IDEX 4028 part cooling fans quickly changing speeds
Hello all,
I have some weird issues with my 4028 12v Part cooling fans connected to my Octopus MAX EZ board. Im in the process of setting up my VC4 IDEX, everything worked fine in CoreXY and Hybrid but since putting in a second toolhead I'm now seeing some issues. Both fans are connected to either the 12v pin on the 2 pin fan port OR the 12v pin on the 4 pin fan port, both work independently (only 1 fan connected to power at a time) and I can ramp the speed up from 0 to 100 without issue. As soon as I introduce the second fan I can only gradually increase the speed of the fans, as soon as 1 fan has a quick increase in speed BOTH fans will stop working. You try to adjust the speed on the sliders and nothing happens, the only way to the fans working again is to reboot klipper.
I've tried a different combination of 12v 4028 fans (Nidec, Sanyo & Delta) but they all act the same way. I've tried an independant 12v PSU to connect the fans and that didn't work. Both fan are connected as per this guide: https://os.ratrig.com/docs/guides/4028/ using the gnd on the heater ports. Any help/suggestions would be very much appreciated.

Part Cooling Fan not working BTT Octopus MAX EZ - New VC4 Build
Hi, I am having an issue getting my Part Cooling Fan to work on my new Octopus MAX EZ board and EBB42 Toolboard. I have set the 12v jumper on one of the FAN ports on the board and have plugged the PWM on the Toolboard according to the build guide but the fan will not spin. I have tested with a second 4028 fan but still nothing. The PWM displays in Mainsail. I have continuity along the wiring so that seems good. My 24v electronics FANs work fine when the steppers start so the 24v rail works. How can I check that I am getting 12V from the FAN port on the Octopus MAX EZ???
Any help would really be appreciated. I hope its not a faulty 12v rail on a new board...
