How thin can my extrusion be from a 1.2mm extruder?

I always assumed that the smallest diameter that you could extrude was equal to the diameter of the extruder tip itself. Recently I heard that you can actually extrude a line that's as little as half the width of the nozzle opening. Is that true in…

Nozzle rubs on previous layers

I'm having a frustrating problem with my recent built custom 3D printer so every single print I made, from the third layer, the nozzle is "rubbing" on the already placed filament. This results in a complete mess, melting the previous layers with…

When building a RAMPS 1.4 based printer, can I safely plugin just some of the components to test if they are working?

If I need to test out some of the components of a RAMPS 1.4 based 3D Printer, can I only plug some of them into the board (not all of them) and test them out? I'd like to test out the NEMA 17 motors without testing the heated bed or extruder. Is…
