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 !
