I'm struggling to find anything based on those part numbers, but if I compare with TBI datasheets then it seems that higher lead screws actually have slightly stiffer ballnuts. Perhaps it's the larger diameter balls.

I still prefer 32mm for Z though, so I've just bought one from Aliexpress:

It was $132 plus $4 for the three extra nuts. I'll get back to you if when I've got the machine back together I'm not happy with the accuracy on X or Y. Thanks for the offer.

Instead of spending money on ballscrews, these encoders look wortwhile:

That and closed loop position control through LinuxCNC would be very nice. About 370 EUR per axis though, so I need to do a bit of research first...

Now I've just gone to the local builders merchants and filled my car with wood and insulation. Going to make the workshop nice before I get too carried away .
