−	The printer is ~~not printing~~. After a ~~total~~ rebuild of the hot end and ~~reassembly~~, we are ~~still having major issues. It was able~~ to ~~successfully print~~ a ~~Wade~~'s ~~extruder gear~~, ~~however~~, the ~~PLA was burning~~ and ~~oozing out of~~ the ~~top of~~ the ~~nozzle slightly. The X~~ axis ~~is cracked near~~ the ~~belt clamp area~~ and ~~binding badly~~. ~~The Y axis also has a lot~~ of ~~wobble~~ due to the ~~weight~~ of ~~the copper plate~~. ~~There are no endstops so homing is~~ a ~~major issue. The extruder constantly strips because~~ of the ~~shallow hobbing and due~~ to the ~~fact that~~ the ~~thermocouples are difficult~~ to ~~use in~~ getting ~~an accurate temperature reading~~, ~~it is hard to figure out what the temperature currently is~~.	+	The printer is now working great.
		+
		+	After a rebuild with a new X carriage (which works very well), a new extruder ([http://www.thingiverse.com/thing:6713 Greg's Accessible Wade's]), the Lulzbot Budaschnozzle hot-end, a new bed, SSR for controlling it, and RAMPS kit with a Mega, things are beginning to come together.
		+
		+	I found that I had a little lash on my X axis after all that, and after some helpful advice in the #reprap chat on FreeNode, I found that Nophead's pulleys for the belts are NOT for XL-toothed belts, the kind I got from McMaster. They are for T5 belts, more common in Europe. I therefore printed a new pulley for the X axis, and the issue is gone! I need to do the same for the Y axis, which I somewhat dread because it means disassembling the bed once again (and having to re-level it).
		+
		+	However, the print quality right now is superb. Some of the issue I was having with printing seemed to be due to the white PLA I was using. Once I ran out of that and switched to green, many problems disappeared. I also noticed that I'm getting a grey plastic ooze coming out of the budaschnozzle in some spots, but that seems to have largely stopped as I've begun using green PLA.
		+
		+	I've printed a full set of frame vertexes with feet which I plan to install shortly (about the same time I replace the Y pulley) and I need to start getting the printer more self-contained (small onboard power supply, RAMPS enclosure, etc.
