There have got to be 3D printer forums that are 'bigger' than here, I imagine?
TBH, I rarely get on here anymore because the SD3 I used to use died and has been sitting in a box while I print with my company's newer Creator Pro.
But I do miss the interface with the SD3 & Repetier software... I even bought one of the last SD3s for home use before they went bankrupt, but haven't really done anything with it.
Two SD3s - One with Sang, One with Printrboard, Fans on control boards!!! Do this!!!, Dual Glass Beds, Blacklight "EZ Bake Oven" - Improves Ambient Temp, Sketchup, Repetier, Slic3r. Graphic Designer & Makeshift Engineer. Drinks Lots and Lots and Lots of Rum.
