The reason for that might be the arcs in the program. I reduced the acceleration of arcs to fix the overage in arc-arc.ngc, but the tradeoff is lower performance when there is a lot of acceleration and deceleration. > While the penguin - (metric so .1 is about .004") > parabolic blend P.1=2:21 Strait G64=4:12 > circular blend P.1=1:41 Strait G64=2:27 > > So - I don't know if that is correct - or there is some issue.

Could you build the program with my debug flags enabled? It will spit out a log that will be useful to diagnose what's happening. Run this command: make EXTRA_DEBUG = '-DTP_DEBUG -DTC_DEBUG' then run Linuxcnc like this: linuxcnc > test.log This works in simulation mode to dump a log of what's happening in tp. I'd like to see if these spikes are visible in the planned motion. Thanks!
