Hello all. I recently had to replace my printrboard which was a F5 board with one main fan connector and the other fan being connected to a isp pin and pos on the hot end
if I remember correctly. I bought the newer F6 board which has two fan connectors, and the ubis/hot end cooler fan works like it should cutting on at 50C. The lower fan(print cooling fan) doesn't work anymore. I did not replace any fans when i did the board upgrade. I haven't changed my g code. Sending m106/107 commands does nothing also.
I use to be able to go into cura and set what height I wanted the print cooling fan to cut on in mm. but it does nothing now. Any help would be awesome. The board is 3 months old and sat in the package for a month till my new psu arrived. I hope the board fan connector is not bad. As i have switched fans around and the bottom will cut on at 50C. The bottom fan also spins up upon switch psu on. hmmmmmm.
Side note my bed while doing it's corner/homing thing makes a two step in the back left corner. Starts there then moves about 6-10mm then homes head back down then continues. another Hmmmmmm...
Ladies and gents, Thanks for any help in advance! You guys rock up in here!!!!
