Quality Control Requirements - 12 Kits at a Time

To test 12 kits at a time, it is useful to set up rapid testing procedures for parts.

To guarantee perfect prints, the following conditions must be met:

Extruder steps per mm are correct. See Triffid Hunter's Calibration Guide
Axes must be able to move freely. See 3D Printer Manual - final assembly for procedure to mount axes
Axis range of motion must be over the entire bed. Do D3D Burn-In for 20 minutes to verify all motion.

See document above.

Optimize Z offset from extruder. Measure variation over multiple prints.
Optimize heated bed temperature. Measure force required to pull a columnar object off the bed using a digital scale

Measure axis tightness using a force meter. Use a Digital Scale to record the force required to move an axis.

E steps/mm must be done only once, and must be captured in Marlin or in Start G-Code
Optimize temperature for a given filament. See Triffid Hunter's Calibration Guide

For OSE's 3D printer stable release, this can be done once: Triffid Hunter's Calibration Guide
