	* ~~Someone successfully printed a~~ new X-axis ~~supporting~~ bracket~~, apparently having~~ zip-tied ~~and hot~~-~~glued~~ the ~~current brackets together among other things. Unfortunately, it seems they did so with 25% infill, which~~ is ~~not going to result~~ in ~~a more stable machine~~.

	* Now the other X-axis supporting bracket has failed, spontaneously while the printer was completely idle. Clearly, we would be looking at major repairs to bring this printer back to fully operational status. Fortunately, that should not be necessary.

	* For TCO accounting purposes, I am noting an estimate of 300 hours highly skilled labor, including substantial planning and innovation, while maintaining this machine. Additionally, the initial cost was ~$600, at least $100 in replacement parts has been spent, and a few hundred dollars of filament has been consumed.

	* ~~An extruder mount bolt came loose and fell out. I replaced it and luckily it happened early in my print, so not much work lost. Looking at the extruder mount more closely now, I think we should plan~~ on ~~replacing it in the near future, it's bowed out and~~ the ~~mounting bracket isn't really a great design, leading me~~ to ~~believe this will happen more frequently the more the bracket is deformed~~.

	* I've installed an 8GB uSD card into the Melzi. Apparently the firmware was compiled with support for it! Also switched the power jumper from USB to the main supply. This means that compy crashes will no longer take the printer out. I also upgraded the printer compy with a donated computer from my former company, now a triple core AMD with 8GB, so slicing now doesn't take hours and hours. The machine is running Xubuntu 64bit and appears to be relatively stable, though I do not recommend printing directly from it now we've got uSD working.

	* Thanks for the update. For a mechanical part like that, "Quality" was appropriate. FYI, "Cheap" parts are now just as aesthetically beautiful, but use less and simpler infill to print much faster. Also, uploaded relevant custom hardware files to [https://github.com/HacDC/PrusaMendel github] . With that, the essential modifications to HacDC's printer are now fully documented.
