Arcspiral.ngc now runs at a peak of 400+ipm - only switches to parabolic blends at the very end of the program (probably where the arcs are not 'tangent' enough). Awesome!
steve.ngc runs in 7 seconds and seems to slow down down in 2 spots (switches to parabolic blends..) Awesome! :) stellabee1 runs a lot faster but.. When running G64P.005 - I get a overage around line 44545. Here is a short example that shows the errror - if you run the program farther - it will have a hand full more of these. says line 23 http://imagebin.org/282452 G20 G0 Z0.0120 G17 G40 G80 G90 G94 S1000 M3 (G04 P3) G64P.005 F999.0000 G18 F999.0000 G0 X3.0560 Z-0.1065 X3.0660 Z-0.0958 G2 X3.0800 Y3.3700 Z-0.0853 I-0.0126 K0.0314 G1 X3.0940 Z-0.0824 X3.1040 Z-0.0889 G3 X3.1160 Y3.3700 Z-0.0814 I0.0122 K-0.0061 G1 X3.1220 Z-0.0830 X3.1260 Z-0.0824 X3.1340 Z-0.0735 X3.1380 Z-0.0745 X3.1420 Z-0.0791 X3.1500 Z-0.0941 X3.1600 Z-0.1020 X3.1660 Z-0.0990 X3.1740 Z-0.1000 G3 X3.1880 Y3.3700 Z-0.0922 I0.0188 K-0.0172 G3 X3.1960 Y3.3700 Z-0.0736 I0.0697 K-0.0189 G1 X3.1980 Z-0.0706 M2 Great work!! sam On 12/15/2013 03:37 PM, Robert Ellenberg wrote: > I think I fixed the issue in the latest commit.
