Results of the Benchy print:
- stringing because of too little retraction as I needed to switch to longer bowden tube after extending the axes
- few skipped steps in Y-axis at the lowest layers. Might be that I have the motor mounts tightened bit too tight. No skips after those at the beginning, though.

- X-axis has banding, it doesn't move very smoothly after all. I suspect that this is because the gear's teeth aren't the smoothest and causes small bumps that the hot end mount structure amplifies. Need to reprint it with Prusa MK2 to get better quality.

- Y axis movement is quite good actually

- overall the quality is passable

So there's work to be done for the rack and gear setup if good quality is desired, especially in X-axis. Also simply by doing more prints, the quality might improve to a point when the parts smooth out in use. Or not .
