EMC2 with Motenc presents slow feed speed | |
I am using EMC 2.4.4 with 2 Motenc Lite board.
The machine has 5 axis of servo-drivers actuators (X Y Z B C axis sequency).
The accelerations of all axis was set to 200mm/s² and the max velocity set to 12000mm/min. When it moves with max feed speed of 6000mm/min using just one axis, the feed speed it is ok.
But when I loaded a Gcode with 5 axis interpolated, the feed speed was up to 1800mm/s.
I tried to set the max acceleration up to 800mm/s². The movements presents sudden variations that create vibrations in the machine and the velocity reaches the preset value.
I note that G64Px.xxx sets the maximum tolerance to optmize speed also. This resource only have any effect if the Gcode have very long trajectories.
Actually the Gcode have trajectories of up 1mm of length.
I don't know what's happen. I appreciate a lot any suggestion about the problem.
