New start

How are the noulei rails?

I have some noulei ground ballscrews for a 3d printer project that I want to do after my CNC build. They look quite nicely made to be honest... the guy I bought all my HIWIN and TBI rails/screws from also had noulei stuff, it would have been quite a lot cheaper.

Some of the chinese stuff can actually be quite good. Admittedly some can be utter crap, but I've had far more positive experiences than negative in recent years.

Well I havent got much to compare to as this is my first machine build :)
But movement is smooth and no apparent play anywhere.
But on the drawings I recived and had my plates milled after said m6 for the 20mm rails. But m6 bolthead don't fit the rails X)
No biggie because I messed up the CAD for the Z dropplate anyhow so it has to be re done anyway.. Will go aluminium next time. 15mm steel feels OTT heavy ;)
The ballscrews look nice and feels good but I don't know if I like the vipers on the ballnuts. Time will tell if they hold up !

If you put the bolt in a battery drill and spin it against a grinding wheel for a few seconds they will fit fine

Yeah, got that advice from jazz also :)
Where is he by the way?
Would have done so if I only had put the holes in the right places on the plate hehe.
The thing I ment is that you should always measure the parts and not trust Chinese drawings!
