Bug? Multi-pass open paths not cutting beyond the first pass
Posted: Tue May 04, 2021 5:28 pm
When cutting paths with zero ramp in multiple passes, all open paths are cut incorrectly: the cutter plunges to the first-pass depth, makes the cut, then plunges to the second (etc) cut depth, then lifts, then goes to the next path. Only the first pass of each path is actually cut. The remainder are just point-plunged.
Also, if a non-zero ramp angle is specified, then only the first pass is cut correctly. The other passes are ended at the end of their ramp-slopes, instead of completing to the end of their paths. Again, only happens on open paths.
Reverse-open-paths is on.

*This operation looks a bit weird as set up for the example, because normally this is set up with the 1st pass 2.999mm, to force the operation to do the same-depth "cut" twice-over (it happens to be with a biro pen and zero RPM). The error was spotted because the ink was a lot darker on the closed paths (letter O) than the open paths (letter L).
