Hello,
Please can anyone let me know what preload they have used on home build CNC router machines when using HIWIN 20 mm linear blocks. As I understand there are ZB, ZA and ZO, I have tried a ZB and a Z0 and a ZB has way too much friction for my Nema 23 3NM motors, so the choice seems to be either Z0 or ZA.
I plan to use the improved SW seals
Many thanks for your help
Rob
