January 28 2016	The X (and to a lesser degree the Y) axis are skipping and it ends up offset. Tightened the belts. All good.	alaina
January 1 2016	Print head not extruding. Mechanics and octopi commands seem to be working fine, but filament does not extrude from print head. Also, the Z axis is off a little, and home is slightly too close to the print head. Easily adjusted by hand.	emmy (saskeah)
January 2 2016	On Igor's advice, I tried pushing through some filament (with the hot end at 185C), and it came through just fine. The pinch wheel needs to be cleaned before using, using the compressed air and little metal brushes by the soldering station. On my to do list (hopefully before end of Tuesday) is to clean out the print head using Igor's "cold push" method, clean the pinch wheel, adjust the Z axis, and re-tape the bed, then print a calibration object to make sure all is good. Also, if anyone else does all of this and wants to print - just a note that the 1.75 inch filament is *super* brittle, so be careful!	emmy (saskeah)
January 2 2016	Cold push clean out of extruder head done, extruder doesn't seem to be blocked. Next step is to clean out the pinch wheel, which is on my to-do before Tuesday, unless someone else feels like taking that on.	emmy (saskeah)
January 3 2016	Pinch wheel cleaned with compressed air. Bed re-taped and cleaned with isopropyl alcohol. Cold push clean of extruder head repeated for good measure (and during a sticky moment unicycledave took the head apart and removed some extra gunk). Z axis adjusted. Attempted a calibration object, z axis held bed too far from the print head. Attempted again with adjustment, print head was too close and scraped the tape. Good news: printer totally functional. Bad news: Z axis still needs tweaking, and part of the bed needs to be re-taped again.	emmy (saskeah)
January 4 2016	Bed re-taped, z axis double-checked. Type A gets my stamp of approval - good to go!	emmy (saskeah)
January 10 2016	Did a test print that came out perfectly calibrated, but with some relatively minor gaps in extrusion.	emmy (saskeah)
January 17 2016	Tried another test print that came out with more pronounced gaps in extrusion. Tried a calibration cube at 220 C, and it came out well. Downloaded the new version of Cura and used the default presets to print another test cube. The presets are fairly different from the previous version, and the test print came out perfectly.	emmy (saskeah)
