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.

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
Bigtreetech-SKR 1.4 Turbo , with 5x TMC2209 stepper motor drives running as
uart input. (about £70)...
it runs 2x extruders and an XYZ 300x300x500 frame with a 230v heated bed.

it's not like I can replace marlin with lcnc on that setup / board?

so I'd need different hardware (at more cost and time to configure) and it
will probably generate the same output using the same slicer.

the acceleration is taken care of in the tmc2209 drives and is nothing to
do with the slicer (I use cura (again free plus seems to meet my needs))

to speed up my prints I use a larger nozzle, given most of the stuff I have
done has been biggish.

not adverse to using lcnc, just not seeing an advantage in cost, time to
build, assemble, programme or finished product.

what am I missing?

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 movements

I still argue that the only thing LCNC lacks is "works out of the box".

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 for a G-code interpreter that used
E as the extruder, and supported the other 3DP-specific codes.

(LInuxCNC supports pluggable interpreters, this is doable)
