Hi allSo, having had my A8 for a few months now (and really pleased with it so far!), I am doing some servicing and upgrades to it - as suggested by this post: https://all3dp.com/1/anet-a8-upgrades-mods/I am doing the bearings - changing from the metal ball-bearing ones to the DryLin ones, but when I screw the blocks back to the plate, they are binding on the rods and there is no way the motor is going to be able to move the plate!With all the screws loose - and I mean properly loose - the plate moves freely and quietly. As soon as I tighten the screws up - even *just* finger tight - the bearings bind.I am thinking of putting some shim between the plate and block, but wondered if anyone else had done this change and had problems?Thanks!
