Hey all,

anyone else have this issue yet?

Had a print fail in a wierd way, and discovered the whole extruder hot as hell, pulled the fan to replace, but it is good on the bench.  
have not yet popped the extruder bord off, thought I would check to see if this is going to be a MOBO issue.

any oddities around the HE fan circuit I’d love to hear about

Some 5015 fan setups will run a screw into the traces on the breakout bord
