Wow, for some reason I thought that normal LM8UUs were ~$10 a piece. Just looked, found them in packs of 10 for $20. These don't look like such a great deal anymore.by shardbearer - General
I found these bearings on Zapp, looks pretty interesting for the Y axis on a Prusa/Mendel, you could bolt them directly to the bottom of your Y carriage. And very cheap at only £4.00! It says they contain a LM8UU bearing inside them too, maybe you could pull it out for use on the X and Z axes.by shardbearer - General

Packing tape is either Polypropylene or Polyester, neither of which has been printed on before. I'll have to try this out once I get mine working!by shardbearer - Printing

Both the metal and printed LM8UU will fit in the felt bushings. Yay for simplicityby shardbearer - General Mendel Topics
What if you were to mount a camera instead of an extruder on a RepRap, and make the stepper move the camera in circles while the head moves around the object, filming the whole time. This would get tons of pictures from every angle, and you would know the exact position of the camera at every moment. No laser needed. The hard part is the software to analyzed it. I think Photosynth can do it.by shardbearer - 3D Scanners, Book Scanners, and Optics
I have an idea! 1. Buy a turnbuckle 2. Throw away the eye bolts, keep the middle piece 3. Drill out the left hand threaded side, and thread it (right handed) with a slightly larger size 4. Put bolts in both sides, attach to Y carriage and bed 5. ????? 6. Level beds! You would want really small turnbuckles, and the bed would be really high above the Y carriage. An alternative with not nearly asby shardbearer - General Mendel Topics
For PSUs, go to an electronics recycler or computer repair shop, and bring your multimeter to test for broken ones. I got a 66W for free out of a broken server You could also make a heated build chamber out of MDF, it would keep the heat from dissipating and lower the load on your bed and hot end.by shardbearer - Reprappers
So, I found a couple old servers at my dad's work, and they have massive power supplies, meant for mounting on racks. Should I use one of these, or just a normal ATX power supply? What's the minimum requirements? I have a 1050W, 660W, 250W, and 140W. +12V currents are 66A, 36A, 14A and 5A respectively. The first 2 are multiple power supplies joined together (I think in parallel) onto one board, iby shardbearer - Controllers
