Post replacing servo with electro magnet (solenoid)
on: December 3, 2018, 16:17

Hi everybody!
I just finished building my first Polargraph machine and Iยดm amazed ๐Ÿ™‚


My goal is to keep it simple and quiet. So I used an MKS gen L (Arduino Mega+Ramps) with TMC2100 drivers. Works fine so far.

But the little servos are killing it with the noise so my Idea is to use an 12V electromagnet for the pen lifting action.

How can I implement the action that the magnet gets 12V supply (over the E1 heater output of the Ramps for example) when "pen up" is called?

Hope somebody can help ๐Ÿ™‚

Cheers, Pascal
