Here a NGCGUI sub was used to compare the original and the new TP.
It is useless code but might show some differences and offers an easy way to try different variables.
The NGCGUI sample configuration was used.
To exaggerate the differences the acceleration of the X and Y axis was set to an extremely low rate of .05
Set for inches.
Use MDI to set G64 Pn Qn before running.
This test was done with G64 P.001 Q.001
There is a move to the start location, a lead in Arc then a circular path made of segments and finally a lead out arc.
The velocities
Original TP...
Lead in arc max 4.74 slows at end to enter circular path.
Circular path max 3.82 - 3.32
Lead slows to 1.5
New TP...
Lead in arc max 3.32 slows at end .04 to enter circular path.
Circular path max 5.24 - 5.02
Lead out slows to .05
Highest circular path speeds at 45/135/225/315 deg when X and Y are both moving closest to the same rate.
There appears to be a dramatic increase in the circular path speed 3.82 vs 5.24.
The transition from arc to segment and back again appears to cause more of a slow down.
To try some text samples NGCGUI and true type tracer might be used.
As a side note auto homing seems to ignore the acceleration settings on some moves in both cases.
