	* November 19, 2012 (mirage335) After months disuse, makerbot still preforms as before. Still useful when RepRap is down or out of PLA plastic.		* November 19, 2012 (mirage335) After months disuse, makerbot still preforms as before. Still useful when RepRap is down or out of PLA plastic.

	* May 20, 2012 (mirage335) Printed a test object (wheel), works quite well. A little excess drooping plastic threads, but probably par for the type of part and nothing that can't be cleaned up.		* May 20, 2012 (mirage335) Printed a test object (wheel), works quite well.

	* September 26, 2011 (Justin) Made my first couple of prints! Via [http://www.thingiverse.com/PaulForest PaulForest on Thingiverse], I found cookie cutters for [http://www.thingiverse.com/thing:8432 Pac-Man] and [http://www.thingiverse.com/thing:8434 a ghost]. They were generated with this [http://local-guru.net/blog/pages/cookiecutter-editor cookie cutter maker] written in Processing, so I tweaked the ghost a bit and printed one of each. The Pac-Man cutter's thicker wall separated from the bottom when I was trying to pull it off of the raft. (Side note: The default Skeinforge settings that came with my Windows ReplicatorG install made what looked like an absurdly large raft. It also assumed the build platform was huge, so the first couple of times it tried to print past the side of the platform. Not sure why that is.) Either way, they seem to have turned out fine, though I haven't made any cookies with them yet: http://yfrog.com/g099agej		* September 26, 2011 (Justin) Made my first couple of prints!

	* August 2, 2011 (Elliot) After a week of playing around, and a bunch of prints, the cupcake breaks again! Yet again, the heater filament failed high-resistance. I replaced it with John's cemented barrel heater (Thanks LJ) which rocks. Here's a time-lapse video of me fixing it. Needs a soundtrack! (http://www.youtube.com/watch?v=fff5scSJA74) Afterwards, ran a 50 min print on it with no issues. Might need tweaking on the PID params or some better insulation, but it's up and running again.		* August 2, 2011 (Elliot) After a week of playing around, and a bunch of prints, the cupcake breaks again!

	* July 19, 2011 (Elliot) The cupcake rides again! I cleaned out the barrel and re-wrapped the nichrome barrel heater. Using a 100k thermistor from John Yang straightened all of the temperature control problems out. We're back in bees-wax! Printed a groovy hollow pyramid to celebrate (http://www.thingiverse.com/thing:8757).		* July 19, 2011 (Elliot) The cupcake rides again!

	* June 12, 2011 (Elliot) I gave up on the experimental hot end because it doesn't seem to transfer heat into the barrel fast enough with the result that it was very very hard to push filament through. I found some nichrome wire (7 ohms worth) and re-wrapped the barrel in the old style. Grrr... So it wasn't the fault of the experimental heater core. Even though it's wrapped in nichrome as originally, the hot end is still exhibiting the same failure -- extrudes around 2cm then stalls, stripping the teeth. In the process, I managed to fook up the teflon insulator -- time to order a new one. Might just scrounge the entire (working) head off the reprap in the interim. This one probably needs a thorough reaming and cleaning out before it'll run again.		* June 12, 2011 (Elliot) I gave up on the experimental hot end because it doesn't seem to transfer heat into the barrel fast enough with the result that it was very very hard to push filament through.

	* June 12, 2011 (Elliot) So the experimental hot end ~~idea I was playing around with is a failure. Basically,~~ it doesn't seem to transfer heat into the barrel fast enough with the result that it was very very hard to push filament through. I found some nichrome wire (7 ohms worth) and re-wrapped the barrel in the old style. Grrr... ~~Still~~ exhibiting the same failure -- extrudes around 2cm then stalls, stripping the teeth. ~~Not so sure it's heat-related anymore. Either way~~, I managed to fook up the teflon insulator~~. Time~~ to order a new one. Might just scrounge the entire (working) head off the reprap in the interim.		* June 12, 2011 (Elliot) I gave up on the experimental hot end because it doesn't seem to transfer heat into the barrel fast enough with the result that it was very very hard to push filament through.

	* June 11, 2011 (Elliot) R. Mark Adams dropped a high-temp thermistor by the space, so I'm working on the hot end again. I set up the extruder thermistor for 10K resistance, and the rest looked good (beta = 4450, base = 25). Tested with a cup of hot water at 83 C and it read spot on. I declare it calibrated. (Also changed platform thermistor to 10K.) On first warm-up, it looks like the new heater will work, but the PID coefficients are horribly wrong and it's overshooting the set temperature by quite a lot. Tweaked a little bit, ended up with P=8, I=0.1, D=12. Not perfect, but not patient enough to tune further ATM.		* June 11, 2011 (Elliot) R.
