Only 2 things that I’ve changed solved the issue.
- I replaced the 5A power supply with a 10A one.
- I tested 1.09
And the WINNER is (for now until proven otherwise) @Robert!
With a new power supply and 1.09 (please join us on the mission Let’s make v1.09 the most stable release yet) the cut seem to be straight. A restricted feed rate might have contributed, there is more to find out.
That I’m able to continue testing in the ‘Heavy Weight’ category is good news.
Thank you all.
