Calibrating Lulzbot AO-101

Andrewupandabout on calibrating Lulzbot AO-101.

From video description:
Tips include proper nozzle removal, reducing extrusion filament issues as the human eye may not be able to see 75 micron layers coming out and filament flow can seize, and knowing that the "calibration print" is a super useful "hacking tool" for accomplishing all of this.

Looks like the video is down. Here is a different video:


Here is an old calibration folder at Lulzbot server:

Felicia Day and Leap 3d user interface

... I can see this technology interfacing with 3d design programs or even guiding your printer as it prints ... and if it captures fingers, could it be used as 3d scanner?

Hot glue gun extruder

3$ extruder! Flash of genius!

From the video description:

Hot Melt Glue Gun HMA (Hot Melt Adhesive) Extruder to make a 3D Printer. It is based on a $3 Walmart Low Temperature Mini Hot Glue Gun. The extruder is driven around by a 3 axis CNC router made from plans from http://solsylva.com/cnc/13x13x5.shtml . The whole thing is driven by an Arduino Uno with a custom set of Shields, a single stepper driver based on a ULN2803 and a parallel port adapter board to drive a 3 axis HobbyCNC stepper driver board. I am using the Teacup firmware that has been customized to driver the ULN2803 stepper driver for the extruder (E axis). All is orchestrated by Pronteface on the PC side with G-Code by Slic3r (converts STL 3D Model to G-Code for Pronterface).

Complete step-by-step guide:

Update: I was told in comments on Reddit that this is nothing new. Basically RepRap started its development with hot glue guns. There is much more information in "A history of RepRap development":


Great work and cool DIY project anyway!
