Do they know you are rotating the nut and tensioning the screw.? Makes big difference.
This is the first 10x5 machine using rotating ball-nut I've built, I've built plenty of 8x4 and the difference between them really surprised me.

The secret is keeping the nut rotation speed down and getting a good tension on the screw with nice straight pull.

Good luck
