One common thing I have seen people do is get the input housing and output housing rotated 90 degrees from where they should.
The bolt patterns for the motor mounting and the VP assembly holes are not on the same diameter, but are close enough that they can be brute forced to "work".
The easy way to tell is to make sure the side bolt holes on the input and output slice are facing the same direction. If they are 90 degrees apart, then you will have problems.
Finally, if you think there is just something wrong with the alignment, then please contact our support. With the tolerances so tight on these gearboxes sometimes a few parts won't mate quite like intended.
As a side note, in the first year we actually sold pre-assembled single stage gearboxes and tested them for current draw. However, strong customer feedback was that the customer wanted to only buy the 1:1 (aka input and output + hardware) and buy the planetaries and ring gears separately. Once this happened, full testing was no longer possible and we needed to rely on our tolerances of the individual parts.
Any, I hope this helps you determine what is going on.
