@blurfl You are the first who caught me 
That’s why I put ‘Not a project’ in the title. I cheated.
If you look how I supported the parts with the cushion of my billiard table, it’s obvious that something is wrong.
The material name is unknown to me in English and also in German, so I can’t look it up.
Some sort of compressed cardboard, or so, with a waxed feeling.
The thickness is given with 3mm, but with 80% humidity it measures 3.4mm.
My smallest bit is 4mm, so it was clear from the start that this will not work.
I cut it anyway because:
- It was a good stress test for FW- and GC-0.83.
Plenty of curves and 6 digits behind the dot plus over 6000 lines of code… - Gave me valuable insight on how DIY RC-Boats are created. (Can be scaled to real boats)
- Feedback on my workflow DXF->bCNC-g-code->Maslow
- Lessons on spacing and placements of holding tabs
- Z-Axis depth control was the biggest lesson learned.
I need a new frame. Z is unreliable because my spoil-sheet is curved like a golf-course.
Too shallow cuts where the sheet bows to the inside and too deep cuts where the bow goes to the outside.
The 2x4s have likely bowled as well under the heat and humidity.
Next frame will be square aluminium tubes welded. - A thin layer of desert dust is perfect to eliminate friction
