Links Into Hangprinter v3 Build Video
On Dec 13-15, 2017, tobben and Tom made a live stream in 4 parts on Youtube, where they built and debugged a Hangprinter v3. The videos are very long, so this wiki page is created as a "table of contents". Help out and fill in if you watch the videos: Part 1, Part 2, Part 3, Part 4.
Part 1
(1m38s): Start
(2m52s): Start of mover build
(5m24s): Snap mover into place
(14m25s): Cracking sounds in printed mover parts (new versions of those parts do not rely on flex anymore)
Part 2
(3h28m12s): "Tell the printer to feed out line"
(3h44m): "Start leveling the mover"
(3h52m1s): "We have six of these Beam Sliders. One on each side gets used for D-line."
(3h54m43s): "Let's bring the print bed in place"
(3h56m20s): "Home position will be vertically below our ceiling unit"
(3h57m24s): Torbjørn uses spirit level on mover
(4h2m30s): Using mover as aiming plumb
(4h4m27s): Drawing marks below mover pivot points
Now going into an hour of measuring this
(4h10m7s): First mover levitation.
(4h12m10s): Measure ANCHOR_A_Y and parallelize A anchor.
(4h13m27s): "As long as the lines between mover's pivot points and anchor's pivot points are parallel, then we're good."
(4h14m1s): "Let's use the number 230" (cm from anchor to mover). Measuring/deciding ANCHOR_A_Y to be 2300.0 mm.
(4h17m47s): Marking out line that is parallel with y-axis.
(4h20m53s): To mark out y-parallel lines, start with going through lineroller.
(4h25m32s): Placing out C anchor.
(4h30m1s): Placing out B anchor.
(4h37m25s): Measuring ANCHOR_C_X.
(4h39m28s): "This thing is cut square." Getting the 90 degree angle between ANCHOR_C_X and ANCHOR_C_Y.
(4h40m25s): Measuring ANCHOR_C_Y.
(4h41m45s): "C anchor will have a negative x-position." ANCHOR_C_X is a negative number.
(4h42m20s): Measuring ANCHOR_B_X.
(4h43m41s): Measuring ANCHOR_B_Y.
(4h44m23s): "Let's do some sanity checking."
Sanity checker's formula:
(4h47m53s): "We are going to make two more measurements." ANCHOR_ABC_Z and ANCHOR_D_Z explanation.
