I am having trouble getting my Prusa i3 accelerating.
I use a melzi board with marlin firmware.
Following configuration:
#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,4000,700} // default steps per unit for ultimaker
#define DEFAULT_MAX_FEEDRATE {500, 500, 3, 25} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values
#define DEFAULT_ACCELERATION 9000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for r retracts
#define DEFAULT_XYJERK 20.0 // (mm/sec 20)
#define DEFAULT_ZJERK 0.4 // (mm/sec 0.4)
#define DEFAULT_EJERK 5.0 // (mm/sec 4.0)
And i use acceleration 9000 in Slic3r to.
Am i missing something? I am new to reprap. I have a custom build thingomatic'ish printer running Sailfish firmware and the acceleration works pretty well there.
Thank you.
