Hi Russell
It will be good to compare notes then!
I guess you have actually ordered the SX2 cos I don't think they sell the X2 now? It makes a difference for the z axis as there is virtually no room on the head behind the motor to mount the screw. I guess this is where the cncfusion conversion comes in. I'm thinking of copying that design although I don't really like the force being on the side of the head. Having said that I have replaced the crappy spring support with a crude counterbalance (a couple of old brake discs on some steel rope!!) on the other side of the head. The counterbalance is an attempt to prevent the known 'nodding' of the z axis (I know about it now, managed not to read about it before I bought the thing)
The fitted screw nuts are steel (!) and have anti backlash adjustment on them, with lots of fiddling with gib strips etc I have about 0.05- 0.1mm backlash on the x and y at the moment. The acetal nuts sound interesting, how will you cut the thread?
Off outside now to start on version 1 of the x bracket.......

Cheers for now
Ian
