The (at least partial) culprit seems to be Maximum Extrusion Area Deviation, which I had dropped to 0 trying to solve the warts issue. Increasing it back to 2000 gets...

Perhaps it would make sense to do something to allow deviation only in one direction (less than ideal extrusion area) rather than either direction so that it can't interfere with...

Thanks for explaining it in more detail. I was under the impression that this option gave it the freedom to over- or under-extrude by some degree to avoid having too...

It's possible that the only reason low values help me is by compensating for https://github.com/Ultimaker/CuraEngine/issues/1495 (not that exact case, but ones where merging inner walls from both sides makes the...

BTW is there or will there be documentation for how the transition threshold settings work now? I found the descriptions in the json really hard to understand.

This can probably be closed as just a configuration problem, but I would like to point out that @Piezoid has a working branch https://github.com/Piezoid/CuraEngine/commits/improve-precision that fixes pretty much all the...

CuraEngine doesn't seem to be performing any such key replacement in custom start/end g-code. Is this something only done by gui frontend, or a setting that needs to be enabled...

That seems like something of a bug in itself, since some of the existing machine definition files include keys to be expanded, and silently produce junk in the emitted gcode...

As a workaround for now, would it work to set `material_bed_temp_wait` and `material_print_temp_wait` to false and add the `M109` and `M190` commands (with no `S` argument) to the custom start...

The `M104` and `M140` commands have to be generated by CuraEngine as part of the normal prologue, since it doesn't support expanding the keys into the custom start gcode, and...
