A small yet expensive box of parts from SDP/SI showed up this evening, so that meant we had what we needed to finish our second beetleweight. We'd ordered a selection of MXL timing belts for the weapon, as we weren't 100% sure what size we needed, so let's see if we can wrap this 'bot up! After finishing Hit Back after viewing an image.
After some test-fitting, we figured out the right size belt and disassembled the side of the 'bot to take the motor out.
We had lost the original 12-tooth pulley, so had ordered a new one, and it didn't take very long to drill it for a 1/16" roll pin, and attached it to the motor.
With that done, the last thing - as always - is wiring the 'bot up. Fortunately in this 'bot we have plenty of space for wiring, and it's just a matter of hooking everything together.
We know it doesn't look all that neat, but it fits. We also trimmed down some of the bolts, as we'd neglected to order some that were the right length, but the Dremel-ish took care of that in no time.
Grr ... the 'bot drives fine (although it could use a the same tweak we did to the previous version with a couple of nuts under the front of the baseplate) but the weapon won't spin up. We even took the top off to see what was going on, whether it was friction, or something up with the ESC, but we couldn't tell, and it was getting late, so we'll have to do a bit of troubleshooting this weekend.
