Very good!
Z-axis won't display any backlash because of gravity ^^
You need to lift it up by hand.
I already replaced a very cheap 2005 ballscrew after 6 month. 0.07mm backlash... replaced it by a C5 ballscrew from aliexpress.
I have c5 sfu1605 with dualnuts
@@cnc_andi3294 nice! Do you have a link for that ballscrew?
Check yixindianqi Store at Aliexpress. You can write with this guys perfectly... very good support..
I used the cheap rolled 1605 but got an extra nut and spring loaded them against each other with Belleville washers. Zero backslash until the spring force is overcome.
@@cnc_andi3294 After trying so many ballscrews, I finally realised I needed a DFU1605 with double nuts
