Dual end stops and extruder

Mostly Printed CNC - MPCNC Advice

Hi!

I have a MPCNC Ramps 1.4 running with dual end stops. Got an idea to try out 3D printing with it.
Is it possible to add an external driver somehow to use an extruder or should I buy a 6 driver board.

I remember having seen similar topic here in the past, but was not able to find now.

It is possible. You may have to sacrifice the screen to get enough pins. But you really just need step, dir, enable:
