Feedback after 2 months of using a Core One
I come from a MK2.5/S which was my workhorse for many, many years. Of course not everything was good in the old days and especially bed leveling was a tedious task to accomplish. That has definitely improved with the Core One and I appreciate this fact. However, there are some points where I wonder how they could make their way through to the market version of the Core One.
A real nuisance is the spool holder. It's simply too short and does not give enough hold. I can't imagine how this passed through the tests. A 1 kg spool regularly falls of the holder and also smaller spools of 0.75 kg of filament do not always stay in place. This really sucks.
Then the whole frame vibrates like hell when printing. My whole table it stands on shakes and trembles. The shock absorbing ability of the frame is apparently very poor and if prints do not adhere well for smaller parts they just get shaken off the print bed. This is physics and I wonder how such things could pass.
Starting a print takes ages, I got somehow used to the filament change procedure which is more complicated than with the MKs but the chamber warming or temperature control takes way too long and is a real drawback. I could also not see that my prints (mostly in PLA and PETG) are better because of this.
Overall I have mixed feelings about the Core One but I am surprised that some aspects are apparently badly designed or haven't received the right attention during development. I hope it gets better in future.
