Topic: Fans Fans Fans

Just need some general info. 

1 - My extruder fan is on its way out, I have no idea what the voltages are for it.  I bought 3 - 12 v .07 amp replacement for it, just wanna make sure i dont blow anything up. 

2 - My y Axis motor needs a fan desperately, when printing it goes over 100 degrees, do I need to wire that to a separate power source or can I splice into the existing fan without overdrawing power and doing damage?

3 - now this is a bit crazy but im going to design a quick plug on off switch for the solidoodle.  basically go to radioshack and bring the power source with me and find a male and female plug that matches, then just plug into the switch first, then have it go from switch to solidoodle, no crazy hacking or board soldering needed.  The question for this one is, could i, if i step down the amps, wire fans in to that setup before going to the board?   The point for all of this is to have as little plugs as possible, but if it cant be done oh well, wanted to ask the experts first.

If Y-axis is literally that hot, your voltage on the y-axis stepper driver might be too high.


Running extra 12V fans off of the 12V line is fine in terms of power drawer.

How would i adjust the voltage?

Use this for your stepper motor with a 40mm fan (12V)

Heatsink should work, Heatsink with fan would really work, Fan will work just a well.
