Update: Loving the hot end fan. i no longer have to print with supports, walls come out cleaner and can print with less infill inorder to get a smooth top layer.by Rolfcore - RAMPS Electronics
hey all. been printing happily for just over a month. But now i am starting to get some strange black sludge coming from the top of my extruder head. (see picture) i think it is just old trapped fillament which has slowly boiled to death inside the head and is now coming back for revenge. it is goopy when hot, cools quickly and becomes very brittle in seconds. Should i be worried? wipe it cleanby Rolfcore - Prusa i3 and variants

Hey all. Im new to 3d printing so please excuse my poor terminology. I currently have one fan connected to my hot end (the aluminum shell heat sink thing). I am wanting to connect another fan which will blow directly onto the print head, for achieving better bridges and such. The only issue i'm having is where do i plug this fan into the board? id like to be able to control this fans speed thrby Rolfcore - RAMPS Electronics
I tried switching the plug around (From min slot to max slot). and this still didnt work. However i found a solution It seems it was a combination of the wrong plug socket and improperly set up firmware. All working nicely nowby Rolfcore - Controllers

I just built my first printer. havent manage to print anything yet due to the Y axis endstop. everything else works fine. its literally just the Y axis endstop preventing me from homing. when i home it, it hits the y axis end stop and keeps pushing (causing an auful grinding noise) and i have to abort. im using a reprap prusa i3. the y end stop stop is at the back of the machine. I tried the M1by Rolfcore - Controllers
