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

(14m22s): Cracking sounds in printed mover parts. New versions of those parts do not rely on flex anymore.

(17m18s): Orientation of extruder motor.

(19m10s): "I want to use a naked mover to make markings on the ceiling plate."

(24m44s): D-linerollers use bowden tube"

(25m42s): The designer who drew D-linerollers made them too narrow. Called him. Now fixed.

(48m30s): Don't trust spools to be 5 cm radius. Measure them and input into firmware the real radius.

(51m5s): Noted down radius onto spool.

(51m50s): Pro tip about spool/gear mounting.

(54m35s): Starting to place out spools.

(57m10s): Important note regarding D-lineroller placement. Rotate them appropriately.

(58m50s): Close-up of wood screw.

(1h23s): Pro tip: Furniture pods on back of ceiling plate.

(1h9m45s): Close-up of mounted D-lineroller.

(1h17m1s): You can tie lines from heat break to corner clamps to support/stiffen up hot end.

(1h18m1s): Pushing 608 bearings into place.

(1h18m42s): Pro tip: route thermistor wire inside heat cartridge wire's heat resistant sleeve.

(1h19m50s): Let's attach some line. 3x5 m on the D-spool.

(1h25m22s): Using one D-line as a reference for the others.

(1h26m20s): The Hangprinter Hitch.

(1h33m55s): Close-up of D-lines tied into D-spool.

(1h35m45s): Tom explains braided/fused line.

(1h37m35s): Keep the three D-lines separate while reeling onto spool.

(1h39m21s): Pro tip: Mark your spools with "A", "B", "C", and "D".

(1h45m38s): Counter sinking hole for M8 bolt the quick and dirty way.

(1h47m30s): Inserting 608 bearings again.

(1h49m15s): Pro tip: Sandwich spacer hard between 608 bearings.

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

Explanation on RepRap forums

(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: Sanity checkers formula.png

(4h47m53s): "We are going to make two more measurements." ANCHOR_ABC_Z and ANCHOR_D_Z explanation.
