Yes! ArcWelder is extremely good at this! Can be used as a console app or
as a plugin directly in OctoPrint if you fancy that. I use it all the time
and not only will you
There are addins now that post process gcode to convert line segments to G2/G3.

This isn’t their fault, there are no curves in STL.

Yes, I know I often fiddle with the output of Cura to do things like switch off
the bed heater after the first few layers, there's probably a setting in Cura
that does that but I haven't found it yet. The point is that slicers generally
have more settings than CAM programs because they have
homing, and it does arcs correctly (all gcode interpreters still slice an
arc in to line segments)

What
the 3d printer gcode is understandable, and you could handball simple
shapes (I've done a couple for various test and setup things). but you
would really struggle to do the infill as well as a slicer to still provide
strength and minimise infill
thanks Andy,
but Marlin does do Delta robots / configurations too (never used / set one
up myself)

It is like the relationship of using CAD to design a part then using CAM to
produce the g code to machine that part. Some people know enough about g code
that they often don't use CAM, or are able to "massage" the output of CAM to
produce different results. Others may not care.
CAD can also

One thing is kinematics. If you have a non-trivial kins then LinuxCNC can
handle it.

I've been happy with LinuxCNC 2.8 as-is for running my FFF printer.

LCNC can easily handle things like a FDM/FFF that over-molds parts or is
built like a lathe and deposits thermoplastics or uses a syringe or
peristaltic pump. The slicers really come up short. They do make up for
the lack of a trajectory planner in some FFF/FDM firmware.

is this not just reinventing the wheel for the sake of it?
what is the benefit of using lcnc for fff/fdm printer?
I am not trying to downplay the idea / application or lcnc or its
capability. (dispite it may appear so)
I ask because I run marlin (free) with octoprint (octopi) (again free) on a
99% of the "magic" in 3D printing happens in the slicer. All the printer
controller needs to do is move the steppers in a very stupid
way.Acceleration limits and such are all done in the slicer. Notice that
the g-code files for some parts are MILLIONS of lines of g-code that do
very tiny

I have heard (but not tested) that extruder moves are not blended, so
the motion is not as smooth as one might like.
There might be something to be said
Gains are all the features already in LCNC for uncommon 3d printers.
Something like FDM + other additive tech. FDM + SLA/DLP for example, or
combined with inkjet.
Still wondering what is missing from LCNC for common FDM/FFF printers.

I think that is all that is missing. A non LCNC solution works out of the
box. It is this "out of the box" that is missing. But the config is
needed not just for LCNC but also the common slicer apps like Cura
The next question is
What are the missing desired or required features in LCNC for
controlling FFF/FDM printers?
