Hello,

By playing with the STL of this topic http://www.cambam.co.uk/forum/index.php?topic=6773.0 I fall on a bug that appears in V1.0 and not in V0.98.

Strange bubble toolpath with shape outline setting.   Shocked

hello David
I dont know why you use a "Arc Fit Tolerance" of 0.08 in your MOP. I use the standard value  = 0. Cambam has to calculate the arc fit tolerance.
Set this to the default value ( =0 ) then the toolpaths are correct.
At this place is a very sharp corner. Also if I set the arc fit tolerance to 1/10 of your value (0.008)

I think this is not a bug. You have forced Cambam to make this mistake.  Wink

Hello Ralf  Wink

It works OK with exactly the same settings on 0.98 (the arc fit = 0.08) so I guess it's a bug.

the arc fit tolerance, I use it for waterline, so toolpaths uses arcs instead of a bunch of small strait lines (it's my default settings) ... but with scanline, this setting must have no effect, there is never arcs in scanline toolpath.
