Hello all-
I am looking to add to my generic mega/ramps setup a way to control the print head such that it is always "facing the direction in which the print head is moving".
Basically, similar to this but without the wire layering: [
youtu.be]
Any suggestions on how to go about this by modifying the Marlin firmware such that the 2nd extruder on RAMPS gives directional commands?
This work is part of this project: concreteprinter.tumblr.com....
Or has someone already done something similar before on Mega/RAMPS?
Thanks ahead of time,
Alex
