Re: BaneBots Gearbox Locking UP
2xCIM at 16:1... Wow! That's a LOT of torque. (And stress... both on the gearbox and the team until this double-d thing gets worked out.)
I can't say for sure we experienced the same thing as we are just using 12:1 trannies with one CIM, but we had some similar "lock up" symptoms and shortened the spacer on the motor shaft and ground down the end of the motor shaft about .10" and everything started to move a lot more freely.
There are some great suggestions towards the end of the "Double-D Reloaded" thread, as well as a .pdf near the bottom of the 56mm tranny page on the Banebots site that can explain this more clearly.
However your symptoms sound slightly different from ours (we had a lot of wear on the end of the CIM where the gearbox pushed the spacer against the motor) so if you have already shortened the spacer and are still getting this lockup problem... my apologies for posting a non-solution.
