I am surprised people still put up with me... I do have a lot of help from the community. The compact 5 configs using the latch and dual stepgens would not have been possible if not for Jeff and Chris's smarts.. (I am the big picture guy usually...)
As far as machs acceleration violations. I am pretty confident that they are real. (again unless I am doing something wrong) If you want to see some huge violations - run the tort.ngc program. It has lots of diabolical motion. (granted - it is diabolical) I think though you should be able to throw any gcode to a control and is should process it correctly. g21 G0 X0 Y0 Z20 G0 X5.394910 Y13.495489 Z20.332291 G19 G2 F500 (225 29) J5.656854 K5.656854 X10.394910 Y26.080547 Z29.989145 G19 G2 (75 14) J-0.258819 K-0.965926 X6.894910 Y26.787653 Z29.282038 G17 G2 (329 285) I-4.330127 J2.500000 X3.858878 Y24.458024 Z31.282038 G0 X0 Y0 Z20 m30 when run through mach and logged shows this http://electronicsam.com/images/KandT/testing/MachViol.png that is 100 in/s^2 when it should be obeying 30.
