HI Guys, I've been busy building a Prusa I3 Ermes Edition and would like to know if I have everything setup corectly on the megatronics v3.0 (the build plans where bad and in french and about older/other hardware ...) where do I connect the Fan i have on my extruder? And do I need to use the jumpers ? did I put the step drivers in the right place ? Thanks for the help :) [attachment 64188 20151016_001439.jpg] [attachment 64187 20151016_001400.jpg] [attachment 64186 20151016_001416.jpg] https://reprap.org/forum/read.php?406,571167,571167#msg-571167 Tue, 21 Jul 2026 21:38:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,571167,571214#msg-571214 https://reprap.org/forum/read.php?406,571167,571214#msg-571214
Make sure that the silkscreen on the stepper drivers match that of the megatronics.

As for the extruder fans: If you would like it to be on all the time hook it up to the 12v line from power supply. If you want to be able to turn it on and off, or set speed you should hook it up to fan 1 which appears to be under the extruder stepper. See picturr
