Hi MrAlvin! Hope things are going well for you. I am upgrading my printer to use a Ramps and a AGCM4. Right now I have a Ramps 1.4 which I modified for 3.3v. I would rather use your Ramps 1.4.4 if that is possible. Not sure if you still have any on hand that you would sell or if there is a way I can get one made. Also if you need any help doing testing of anything I would be willing to help as mby SwHwMagic - RAMPS Electronics
