- in camlib.py, CNCJob class -> generate_from_excellon_by_tool() was
failing in the line to sort the tools due of been unable to compare
between dict's. I replaced that section.
more detaild error print including python trace when more complex unknown error
reinplement drillcncjob
fix camlib problem with all drills("all" was already there) but it crashes on tools without points, when no tools "all" is as default
add timeout to all helps if command is signaled
implement executing of tasks inside worker thread
cleanups, reimplement Isolate/New/OpenGerber as OOP style Shell commands
disable edit during shell execution, show some progress
add ability for breakpoints in other threads and only if available
add X11 safe flag, not sure what happen on windows
The tools are ordered by diameter as I found that the tools order in the Excellon file is not always diameter based. There is also a plated / no-plated holes criteria.
The tools in the GUI tool-list are selected all by default.
If the user wants to select only some tools, he should be carefull when selecting the tools as the order of the selection will be the actual order of the tools in G-code.
The polygon passed to clear_polygon() is generated using shapely’s buffer() function on line FlatCAMObj.py:1095.
When the margin given to the buffer() function is small, a single Polygon object is returned. If the margin is large enough it causes the polygon to be broken into pieces and a Multipolygon is returned instead. A visualisation of this can be seen in the shapely manual in the object.buffer() section.
The first thing clear_polygon() does is buffer the polygon again to take the tool diameter into account and the Polygon/Multipolygon generated by this is handled further down the function. The buffer() function used to take the tool diameter into account can be called happily on both Polygon and Multipolygon objects so there is no reason to block Multipolygons being passed to clear_polygon().
Therefore simply adding Multipolygon to the acceptable types in the assert statement on line camlib.py:382 fixes this bug and causes no further issues.
