Hey!
We bought and assembled 4 AndyMark mecanum wheels.
The rollers seem to be tight, as in not turning well, therefore prohibiting the robot to 'crab walk'. Our next step would be to add a couple of washers to the six center spacers to ease tension on the rollers. Has anyone else come across this problem? Has anyone tried any type of lube (don't want to make our $$ wheels all messy unless if we have heard someone else has tried it

)
BTW, I'm not on the mechanical team. I just need these wheels done and mounted so I can start programming, so I've decided to take the initiative to getting that done sooner.
