Basic instructions for the HacDC Lulzbot 3D printers

Create your model with ImplicitCAD or OpenSCAD. Creating your model is beyond the scope of this document, but the two previous links include documentation. The model will be saved with the extension or .escad or .scad respectively.

This should then be exported as a structure file with the extension .stl. OpenSCAD can do this from the File -> Export menu. ImplicitCAD appears to use a separate program: 

   $ extopenscad model.escad model.stl

While the .escad and .scad files are unique to the apps above, the .stl file is a standard understood by many programs. Some(?) printers understand STL files directly. Our Lulzbot printers are not among them. The STL file must be further converted into a series of instructions that tell the printer exactly how to calibrate, heat, move, extrude, and cool.

Again there is a widely used standard: G-code. G-Code files, logically enough, typically have the extension .gcode. Cura, among other programs, reads STL files and produces G-Code files. Slic3r is another such program. (See the Slic3r manual for more info.)

Use Lulzbot's Cura, not "standard" Cura!

Turn computer and 3D printer on

After boot, login as root. The password is printed on the monitor.

Insert USB stick or get your .gcode to the computer by other means

Command Notes
$ lsblk List USB devices
$ mount /dev/sdb2 /mnt Mount USB
$ ls /mnt
$ cd /mnt
$ ls
$ pronsole
> connect
> settemp 190 Remove any filament that may be stuck in extruder
> load .... Tab to complete name
> print
> monitor
> exit


The Lulzbot Mini will eventually move the extruder head up

Command Purpose
$ pronsole
> connect /dev/ttyACM0 or connect /dev/ttyACM1
> home x watch the printers to see which responds
