Okey! Big problem (maybe). The basic parts for my build have arrived. Got wrong carriages for the rails. Got 2 wide and 4 pillow bearings, should have been the opposite :(
Well it's no biggie.. moving on!

Got 1610 for all ballscrews even though I ordered 1605 for z screw! Will this be alright if I use pulley reduction 2:1?

Have gotten full refund for the screw and compensation for the bearing so I can't really complain about the seller, probably a factory worker that had an off day :(

So what do you guys say about 1610 screw for z?
