I have reprinted most of the parts of my prototype for various reasons. Some of them were just weak from poor print quality (My printer was acting up a few months ago when I printed most of them), others needed minor changes.
The original part is the grey one above and the new one is the white one below. I added a extra pulley to help the belt path.
I ordered 0.2mm pitch belt and pulleys, which are very nice.
I have also finished assembling a Sanguinololu set and mounted that to my plywood side.
I designed a smaller version of the Makerbot mechanical endstop which I plan to upload soon as well. My version is designed to support 3 or 4 wire connections. The boards were fabricated by the DorkbotPDX PCB service which makes very high quality purple PCBs.
I have some connectors and wire on order to finish wiring up my motors and should have a video of it moving by next weekend. The next steps will be to finalize my extruder and hotend plans and then it should be printing.
