How can I adjust the plunge rate? When I cut the rate into half, the ramp itself does not change (just the speed). With wood I would not bother. But with aluminium, I often break the bit when I can’t lower the diving angle.
Maybe this is a bug in
ease-down? It should use the Z plunge rate instead of the XY feedrate.
The choosen feed rates are correct:
G21 G90 G0 X7.5875 Y7.5875 F6000 G0 Z2.0 F2000 G1 X10.4125 Z0.5875 F20; --> dive G1 Y11.1749 Z-2.9999 G1 Y24.4125 F300; --> mill ...
But I’m looking for a less agressive diving factor.
Perhaps with with
ease-down the diving speed is equal the xy speed and the
plunge rate affects the diving angle?
G21 G90 G0 X7.5875 Y7.5875 F6000 G0 Z2.0 F2000 G1 X10.4125 Z0.5875 F300; --> dive with xy feed rate G1 Y16.0 Z-2.9999; --> expand diving path from Y11.1749 to Y16.0 or so... G1 Y24.4125 F300; --> mill ...
Older code used to interpolate between XY and Z feeds on ease down / contouring. It caused some trouble, so I backed it out. It will be re-introduced with a new algorithm probably in this dev cycle.
