Howdy Group!
I recently got my first 3D printer, Geeetech Pro B (i3 clone out of acrylic).
I’m trying to calibrate the extruder multiplier - I got e-steps working within a percent or so, but I see a lot of different methods for calibrating the flow - and I’m not even sure what I’m trying to achieve?
Specifically, what size should I be TRYING to extrude - I have a 3 mm nozzle, and when the software asked for 400um the printer gave me 330. I’m using Slic3r and I’m not sure in vase mode if I’m getting an “external” or “internal” perimeter, but the g-code said:
; external perimeters extrusion width = 0.30mm
; perimeters extrusion width = 0.40mm
; infill extrusion width = 0.40mm
; solid infill extrusion width = 0.40mm
; top infill extrusion width = 0.40mm
So I bumped it up 19% to get 400um.
Now after watching https://www.youtube.com/watch?v=a1vH3ge-V3Q I like the sound of their approach, as well as another guy who says to print 2-3 layers.
What’s kinda the right approach?
