Craig,
If you used "released FlatCAM" that was probably version 8.5 and yes that was NOT impressive. If you used the beta that was FlatCAM 8.994 and I've found a few small bugs but overall it's pretty solid. The primary problem to me is the documentation is ancient and all but useless.
To me there seems to be some inconsistency between what FlatCAM is programming and what is getting machined. When I look at the motor it appears to have ball bearings and I don't really see or hear anything that suggests excessive runout but I can't be certain. This is why I got into the discussion about PreciseBits but those people seem to think their tools are so precise even RUNNING them on my spindle would destroy them!! Would it be a reasonable "hack" to just keep opening up what I'm TELLING FlatCAM the tool width is until I get some sort
of correlation with the trace width I was asking for? I understand Fusion 360 isn't terribly expensive but I've already studied this system, to just drop everything and start chasing down a
totally new rabbit hole makes no sense. I could consider Autoleveller maybe a little after I get past this initial stage, what does it require just Java 8? I just want to start getting some USABLE boards out of this thing, "perfection" can come later, but I'm listening for any reasonable ideas.
