Re: Horizontal lines - 9 years ago
I do have the old Z couplings with PVC and I haven't touched them since I built the printer. The threaded rods do seem to gyrate but I didn't think that was an issue due to the smooth rods holding the X axis in place, maybe replace the threaded rods? Would this explain the different texture based on the layer it is printing?by lexman26 - Mendel90
Re: Horizontal lines - 9 years ago
Hey Nophead, so I reprinted the two main parts of the X axis and the brass nuts couldn't be tighter. The '2nd Dice' files are what I printed straight after I reassembled it, the '3rd Dice' is the one that I turned off the bed exactly 50% through the print. The 2nd dice is very similar in print quality to the first but the ridges are a little bit smoother and less pronounced. The ridges match up oby lexman26 - Mendel90

The brass nuts don't seem to be completely sung inside of the X motor bracket and X idler blocks. It makes sense because I reprinted them following the change to the way that the X axis smooth rods were clamped so my prints then could be at fault. I will re-print them again to make sure the nuts are snug and re-assemble. In the mean time here is a geometrical 20mm dice. Thanks.by lexman26 - Mendel90
Horizontal lines - 9 years ago
Hi there, I have had my Mendel90 for some time now and gotten over all the major hurdles but the layers in the side of my prints have always been slightly bumpy. I mostly print mechanical parts so it isn't much of an issue but some parts I would like to look slightly better. I have done some looking and no suggestion I have found has made much difference.
