RAMPS 1.4 fan mount 40mm by CivilEITprint Feb 11, 2013


This is a simple symmetric bracket that mounts on the RAMPS shield. No screws required to attach the bracket to the board. Fits 40 mm fan with bolt spacing 35 mm (1.4") outside to outside. Three improvements have been added. Nut trap on the inside, small skirt to channel air, and increased depth to not interfere the stepper wires,

Thank you for taking the time to write this. I will try this soon!

Right beside your X-Axis Pololu chip just to the left is an innocent looking 2 pin connector, thats where your fan plugs in.to cool your chips. If it doesn't turn on, it could be because it's not enabled in your firmware. It's referred to as Pin 23 in Sprinter and Marlin. In the firmware you can also modify it's operation to run when it prints or keep it constantly running.

If you look at the pictures for Thing 30331, you can briefly see where fan plugs in.


Can you explain more? Maybe a pic.

Use any RAMPS mounts (not enclosments) to mount your board to the fram. Then attach this simple device and wire your fan into D9. Use Gcode M106/107 to turn fan off and on.

Why waste your printbed fan control for cooling your RAMPS board? Just wire the fan to 12vdc!
