Itty Bitty Double Extruder

I have been thinking of adding code to merlin to move Y and pulse an output pin at a settable Z interval like every 1mm for clean timelapses what do you guys think..

Ramps 1.4 has servo headers servo 1 is also tied to D11 I think not check in a long time . All output pins from the avr are 5v that's why it's best to use mosfet and stuff rated for use with logic voltage..at 5v you can get away without but at 3.3 or 1.8v you must them or switchthem off high rail using a darlington pair
If you want a custom fan expansion board just ask
Side note testing halleffect endstop modied with 10 turn pot and ref vreg and filtering works amazing so far and you can hide it 1/4 turn = .008mm Z
