All, I have a dual boot computer configured with both Windows/Mach and Linux/EMC2.4.6. I ran Steve's code on both systems and the problem that he describes is evident when running the code on EMC, but not on Mach.
To answer Jon's question: > Does it start out running well, but then the slowdown develops later in the > part program? No - The problem is apparent at the first G2 move. The machine appears to change feedrate between G2 and G1 moves. Moving from one G2 line to another G2 line is smooth, and moving from one G1 line to another G1 line is smooth. G1 moves appear to run at around 60% of the feedrate of the G2 moves, so the transition from G1 to G2 (or G2 to G1) makes the machine seem erratic. If I slow the feedrate down, the problem persists. My test machine is a stepper machine - the change in feedrate is even more noticeable because of the change in pitch at different motor speeds. I don't think that this is a processor power issue, as I can reproduce it even after deleting all but the first 6 lines of motion code (leaving the safety block).
