Yeah, I've noticed sometimes that the rollers on the gantry don't spin either because they aren't in contact with the ground steel top plate, or they are too tight and get drug along and don't spin.
I've measured the difference between the gear rails at both ends and they differ by maybe 1/16". I suppose we should make another attempt at seeing if we can get it closer to zero difference?
Thanks.
