In order to facilite robot-mongering, I've been building a 3D printer. Specifically, it's a Prusa i3, assembled with an MDF laser cut frame, and a casual disregard for instructions.

(Manual) Calibration points for my Prusa I3:

G1 F3000
G1 X0 Y30
G1 X0 Y200
G1 X150 Y200
G1 X150 Y30

Some notes on auto bed levelling:

Just a few things left to do:

[x] Cut 5/16 smooth rod to fit Z and X axes.
[x] Cut M5 threaded rod to fit Z axes.
[ ] Turn hobbed bolt to actually fit through 608 bearing.
[x] CAD up print surface.
[ ] Laser up print surface.
[ ] Mount and wire up limit switches.

Which means a little shopping left.

[ ] 4x M3 hex screw for print surface levelling.  Length 20mm?
[ ] 1x M5 hex screw to draw m5 nuts into place.
[x] 6mm acrylic for print surface. (Found in the shop).
[ ] Blue painters tape.
[ ] 5mm ID aquarium tubing.
[ ] 4x 8mm? ID hose clamps.

Following on these earlier notes, I have the following parts left to print:

  • x-end-servo (2 hr 29 min)
  • x-end-idler (2 hr 4 min)
  • x-end-tensioner (28 min)
  • x-carriage (1 hr, 51 min)
  • y-belt-holder (45 min)

So thats 7 hours and about 37 minutes remaining.

Next up on the Y-Axis, I need:

[ ] 2x 370mm 8mm (5/16") smooth rods
[ ] 2x 400mm 10mm (3/8") threaded rods
[ ] 4x 205mm 8mm (5/16") threaded rods
[ ] 22 5/16" nuts
[ ] 22 5/16" washers
[ ] 12 3/8" nuts
[ ] 8  3/8" washers
[ ] 4  3/8" fender washers
