Prusa I3 Ermes Edition and Megatronics v3.0 problems
October 15, 2015 06:29PM
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 smiling smiley

The jumpers go underneath of the stepper drivers to set microstepping drv8825 drivers all three pins jumpered results in 1:32 microstepping.

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
