acceleration?

[kakapoopie]

Hi all, is it possible to have acceleration in CW?

here are my sprinter settings

// X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
#define _ACCELERATION 3000 // Axis Normal acceleration mm/s^2
#define _RETRACT_ACCELERATION 3000 // Extruder Normal acceleration mm/s^2
#define _MAX_XY_JERK 20.0
#define _MAX_Z_JERK 0.4
#define _MAX_E_JERK 5.0 // (mm/sec)
#define _MAX_START_SPEED_UNITS_PER_SECOND {25.0,25.0,0.2,10.0}
#define _MAX_ACCELERATION_UNITS_PER_SQ_SECOND {5000,5000,5000,5000} // X, Y, Z and E max acceleration in mm/s^2 for printing moves or retracts

Thanks,
Vaughan

Acceleration would be handled entirely by the firmware. Right now you accelerate at 3000mm/s^2. Lower that number to make the acceleration more visible.
Stepper moves in dlp systems are so small that acceleration is hard to see... I personally think that acceleration in these systems is largely unnecessary

That did it! Thanks Pomeroy.

I'm doing it because my carriage is heavy and moving at high speeds was jerking the whole machine around
