I want to keep track of some of the modifications that I do to my Printrbot LC since others might find them useful. Also it will be interesting to see how what I do changes over time.
1:
The first modification that I did was to place little pieces of silicone fuel line as washers under the printbed to allow it to be leveled. This tubing is the type used for R/C models to connect the fuel tank to the engine (which I had laying around). The tubing can squish down a bit so you can vary the height of each corner of the platform. This seems to work OK, however I still cannot get the bed perfectly level.

I noticed that the heated printbed takes forever to reach 90C and will almost never reach 100+. It is a bit cool in my apartment, so that might be part of it, but I also think this might be a sub optimal design for the printbed. So to try to make it a tad more efficient I placed a layer of aluminized mylar film under the wooden platform. Maybe this will conserve a bit of the heat. Ideally this would be directly under the heated plate, however I did not feel like taking it off, so we shall see how this works.

I decided that mod 1 was not working well enough for me, so I switched to using springs instead. I was originally thinking of making these however I have springs laying around so that was a simpler solution. Essentially it accomplishes the same thing. I was able to get the printbed very level which greatly enhanced the quality of the print so far.
