April 29, 2013 Printed and installed new extruder feed gear to reduce backlash during retraction.

Observed inconsistent extrusion. Small gaps appearing in extrusion, yet full infill occurring on layers otherwise (ie: not clogged).
Investigation pointing towards slipping knurled bolt in feeder, or more likely, old wet PLA causing problems.

Norm
April 27, 2013 Print quality degraded significantly mid-print. Hot end disassembled, burnt PLA removed from brass tube, and dust/dirt removed from teflon-PEEK interface. Print quality returned to normal. Clogged again, cleaned more thoroughly this time. (Used 1/8" drill bit to handheld scrape out burnt PLA very carefully.

PLA diameter changed.

Norm
April 24, 2013 Squeaking noise observed from Y axis axle.

Endcap inset screw noticed to be loose, requires new endcap to be printed, and screw not to be overtightened.

Norm
April 12, 2013 Bed leveling assist tool printed and built. Norm
April 8, 2013 Belts retensioned, new bearing endcaps installed to reduce backlash further. Norm
April 6, 2013 Z axis calibration fixed, Z steps/mm in new profile on Git.

X/Y axis backlash observed, infill not meeting walls, delamination observed.

Norm
March 31, 2013 Z axis calibration issues observed.

25mm Test cube showed ~6.8% Z axis error.
