While I have some v1 sled issues to overcome…
a 1/4" Downcut Bit, 700mm/m, 10k rpm was quite happy to cut 4mm deep and probably could go to 6mm, leaving an exceptionally clean cut. edit: through 18mm home depot ‘cabinet’ grade ply.
Assuming one has good ‘adhesion’ of the sled to the workpiece, via a well balanced and parallel sled, good frame angle, and enough mass on the sled, the router sounded like it wouldn’t complain about a little more load, maybe another ~50%, either in speed through material or depth of material.
I was disappointed to find that full 3-axis movement hasn’t been implemented yet. the most ‘disjointed’ aspect of my cuts and the place where the most improvement, towards consistent manageable loads (and presumably the most ‘fluid’ motion possibilities would be with the Z-axis keeping up with X-y motion to ramp in and maintain a constant load across the whole cut vs the current ‘plunge’ (which pushes back on an unmoving sled), ‘cut’ which starts the sled under inertial resistance, and the new cut load, and ‘stop’ (inertia + load).
It seems to me that the most appropriate way to maintain precision is to ramp up the load gradually and maintain a stable load for as long as possible up to the limits of the motors to the material…
Without a fluid 3axis motion this is impossible.
