I build the BLV MGN Cube from Ben.
Now I‘m very satisfied with the printer and the print results. I got some real problems with the first prints, but Ben helped me out.
The problems I got, came from the flanked bearings I ordered from Amazon. They were the most expensive one, but they have an absolute Bad quality. Now I ordered from a local german store and o mich better quality. The first print after changing all 24 bearings was the calibration cube (See picture) without any additional adjustments in the slicer.
I put some pictures here from the first prints with the bad bearings. And also from the bearings itself. You can See the radial play. The screw has a play of 5mm over 30mm length. Some of the bearings lost their cover and most of them lost their grease.
Be aware of cheap stuff. It may result in the same frustration I got.
