A preset whose layer height exceeds ~45% of the outer wall line width has
less than ~6 degrees of reserve on a 45 degree wall (max self-supporting
angle atan((w-h)/h)), and support cannot compensate because the 45 degree
stair tread is only h wide - far below one support line. Those presets are
not usable in practice, so shipping them only invites failed prints.
Removes the 22 rungs above h/w = 0.45 and prunes them from the vendor
index. What remains per nozzle (default first):
CHX 350 0.4: 0.18 | 0.6: 0.24 0.28 | 0.8: 0.32 0.36
1.0: 0.44 0.48 | 1.2: 0.48 0.56
MBL 0.4: 0.18 | 0.6: 0.24 0.28 | 0.8: 0.36 0.34
1.0: 0.44 0.48 | 1.2: 0.48 0.56
The 0.4 nozzle keeps a single rung: 0.20 mm would qualify (h/w = 0.435) but
divides both screw leads evenly (4/0.20, 8/0.20) and stays excluded by the
Z-artifact rule, and 0.22 is already at 0.478.
Also corrects the MBL 0.8 default to 0.36 mm, which at w = 0.92 sits at
h/w = 0.391 and therefore still satisfies the stricter 40% default rule.
