X-axis seems too tight

I am very close to completing the assembly of my M3, and I have been very careful so far and everything is coming together nicely. Great job on the instructions and getting all those parts labeled and packaged. 

So I have a question. The X-axis rolls smoothly but seems to have quite a lot more friction than the Z or Y axis. It was stiff before the belt was added, right from the time I put it on the 2040 V rail. The eccentric spacers are in their most slack position. The polycarbonate wheels aren't deformed and when left for a few days do not develop a flat spot.

Do I continue to finish the assembly, or should I disassemble back to there and try diagnose the issue? Perhaps drilling out the X-axis frame ever so slightly might be a way to get more to use the eccentric spacers to get the right tolerance?

Hey Philip. Is it possible that you have a V wheel put together without a washer in between the bearings? That can be a source for tight motion. The spacing on the X plate is right where we want it.

Can you roll it be hand?

Derek, I will double-check, but I believe I assembled them correctly. I'll post here when I know.

I tweaked a few things and it seems to be running fine now. I can't really explain i, but its smooth and ready for the next step.

Thanks
