For anyone who wants to experiment with settings for trochoidal
milling, there is now an adapted version of Bertho's program for
git master for use with [py]ngcgui:
nc_files/gcmc_lib/trochoid-path.gcmc
The routine is included by default as a tab in several sim
configurations for gcmc usage.

well - it could do the velocity.. but the acceleration is set pretty
safe (not too many spare parts.) iirc 10in/sec^2 or something like that.

Indeed, with that setup the trochoidal path will
the limit of sim is 1800mm/m - so if you change all the axis velocities
to 58mm/s (3500mm/m) it peaks at 2900mm/min. Upping the acceleration to
1000mm/s^2 makes the program run at 3000mm/m steady.

Yes, I also suspect the centripetal accel limits may be a problem here.
You ca
Could you post that gcode somewhere? (I don't have time right now to
play with your cool scripting language..) It could be the centripetal
accel limits of the spirals..

I just tested trochoidal milling using the example I created for gcmc:

- source: https://gitorious.org/gcmc/gcmc/source/exam
some more random paths running the circular arc blend rc3...
