Apparently this has to do with how Marlin uses timers. Pin 11 uses a timer that it uses elsewhere so if you try to set a value to that it jacks up other stuff... I found this thread which got me on the right path. You need to use the D4 and D5 pins for these outputs. If you have one of the RRD Fan Extender boards that seems to want to work on D6 and D11, you can just slide it away from the resetby snowzach - Firmware - mainstream and related support
I have a Ramps 1.4 (from Makerfarm) and it's worked for well over a year without issue. I've having strange problems lately where it will just reboot in the middle of a print.

I used to have the whole printer in a cabinet and figured it was due to heat, now I've cut a hole in the cabinet and have cool air being blown by a fanby snowzach - RAMPS Electronics
I had nothing but trouble with my Magma Hot end.. I really think it had a machining issue or something, it wouldn't extrude properly.

I really think that it's odd that the inner tube only contacts the heatsinkby snowzach - General
