Machine Slow on Curves

[m_c]

There's a new LinuxCNC projectory planner being written, as the existing one has issues in some key areas.
Ironically the discussion about it was on the Mach yahoo group, as somebody had swapped back to Mach3 to get better performance - https://groups.yahoo.com/neo/groups/...essages/143177

When the machine follows a curved line, both axes are accelerating. If the acceleration setting in the motor tuning is too low, the machine will therefore have to slow down. So check what your X and Y accelerations are set to.

Edit: The above is probably irrelevant, didn't spot that you said it was fine with circles.
