We've had the opportunity to put together some 3D printers. Here are some notes on that

Notes:
- When printing parts try to include T-slot nut cage forks so they don't slide away when you remove the screw. Perhaps with small barbs so they are pulled tight.
- If any steppers are skipping steps you might want to adjust the Pololu driver board's current limit. As described in the links below.
- CS for bottom plastic plates, are M5-7.
- Other part numbers for Extruder motors are:
- 36JX30K5.18G/42STH38-1684A, 1.8 Degree, 2.8V, 1.68A 1:5.18 Gear Ratio
- 36JX30K27G..., 1:27 Gear Ratio
- 36JX30K100G..., 1:100 Gear Ratio
- Hot End Cooling fan: AV-F4010LS
- 24V 0.08A 4-6? CFM

- 5 mm aluminum sheet
- I think it's 3/16 though
Adjusting the Vertical Slide rods:
- Mount clamps in the base with locktight, but leave M3 screws lose.
- Slide plastic gantry mounts with bushings on the slide rods
- Thread the lead screws in also, add retainers and holding screws.
- Add Claps to top of rods
- Slide T-Slot nuts into top piece for the clamps.
- Loosely mount motors
- Slide rods into base clamps and connect motors to torsion dampeners.
- Loosely fasten in upper clamps.
- Tighten all four M3 bolts on clamps
- Measure distance to 80/20 at bottom of slide rods.
- Tighten top clamp screws without locktight enough so you can still move the clamps a bit
- Adjust top of rods to same distance and tighten one clamp screw till its firm.
- Add locktight to the other one and re-thread and tighten.
- Remeasure to double check distance.
- Add locktight to the first one check distance and tighten
- Repeat for the other rod.
Adjusting the lead screws and motor mountings:
