I have the same years of experience.
But the result of your printer output is defined by minimally 3 factors:
- Printer
- Slicer (including profiles)
- Filament
Simply stating that the printer is the issue is a bit short sighted. Even if cheaper printers do the job better.
Yesterday I printed a test cube with a poor ABS profile and the 2 walls of a 10mm hole were somehow not properly bonded to the previous layer due to too much cooling. Is the printer the issue then?
The cooling on the H2D is quite strong and needs adjusting sometimes.
