Re: AndyMark Parts Feedback 2015
We ran into a couple of issues with AM parts this year. First off was shearing off the output shaft of the PG-188 when back driving it. That was not expected at all. We ended up taking off the PG-188 in the end anyway. Second was having an issue with the AM Planetary gearbox. The shaft was undersized by a few thousands (we mic'd it out). It looks as if it was made to 5/16 rather than 8mm, so the press fit gear we were using was slipping on the shaft. We tried knurling the shaft, and that seemed to work, but we eventually replaced it with a MiniCIM after finding some weight because we were unsure about how long the knurl would last.
The tough boxes worked great. We CNCed a new face plate out of .050 2024-T3 to lighten them up a bit and that worked a treat. We also used a couple of 32dp gears from AndyMark, and we didn't have any issues with them, so that's a plus.

Something has gone awry this year in FIRST. I think more teams are concerned with winning and their robot that they don't even stop to think about the kids on their team, or the learning experiences of others. - Amanda Morrison [more]
