UPDATE (11 Sep 2016): New pictures uploaded. The printer has been taken apart for a rebuild with new motor brackets, replacing astrosyn dampers with cork gaskets to reduce noise. An MDF base with rubber feet underneath is integrated, and wiring is cleaned up. A quick video has also been added: https://youtu.be/67SkcQzqlso UPDATE (27 Aug 2016): The BOM has been uploaded, a suggested list of parts and sources that is about 98% complete. There are some odds and ends you may need to get. This is Version 2 of the BazBot, with all old V1 parts being replaced by V2 parts. An updated BOM list and sources will be uploaded soon, sorry for the delay. The build volume remains the same: a 350mm diameter plate and a max build height of about 400mm (untested at home, where the effector is at 440mm). Here's a clip of the V1 printing some V2 parts: https://www.youtube.com/watch?v=n2VkAJE5SZQ Another video has also been added: https://youtu.be/zdjuW7R2pAE. Thermal IR pictures have been included, showing how heatsinks on NEMA motors work well and the MDF lower build plate support does a good job as an insulator. The aluminum plate under the mirror distributes heat from the Kapton heating element evenly. M3 screws are used to assemble the effector, attach hall effect endstops, bolt carriages to linear rail carriages, attach NEMA motors, and bolt linear rails to aluminum extrusions. M5 screws are used to bolt aluminum extrusions to printed vertices, hold plate holders in place, and attach extruder to the aluminum frame. Future upgrades include 45-degree carbon fiber top supports that will greatly stiffen up the frame and prevent torsion.
