Ieri ho fatto un po' di prove di movimento..

Questi sono i settaggi che ho su MarlinKimbra di default, leggermente modificati da me, per i movimenti

// MOVEMENT SETTINGS
#define HOMING_FEEDRATE {100*60,100*60,10*60,0} // set the homing speeds (mm/min)

// default settings
#define DEFAULT_AXIS_STEPS_PER_UNIT {160,160,200,1476,625,625,625} // X, Y, Z, E0, E1, E2, E3 default steps per unit
#define DEFAULT_MAX_FEEDRATE {300,300,10,80,100,100,100} // X, Y, Z, E0, E1, E2, E3 (mm/sec)
#define DEFAULT_RETRACTION_MAX_FEEDRATE {400,150,150,150} // E0, E1, E2, E3 (mm/sec)
#define DEFAULT_MAX_ACCELERATION {3000,3000,50,3000,3000,3000,3000} // X, Y, Z, E0, E1, E2, E3 maximum start speed for accelerated moves.

#define DEFAULT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // E max acceleration in mm/s^2 for retracts
#define DEFAULT_TRAVEL_ACCELERATION 3000 // X, Y, Z acceleration in mm/s^2 for travel (non printing) moves
// Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
// The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
// For the other hotends it is their distance from the extruder 0 hotend.
//#define HOTEND_OFFSET_X {0.0, 5.00, 0.0, 0.0} // (in mm) for each extruder, offset of the hotend on the X axis
//#define HOTEND_OFFSET_Y {0.0, 5.00, 0.0, 0.0} // (in mm) for each extruder, offset of the hotend on the Y axis

// The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously)
#define DEFAULT_XYJERK 10 // (mm/sec)
#define DEFAULT_ZJERK 0.4 // (mm/sec)
#define DEFAULT_EJERK 5 // (mm/sec)

Con questi settaggi estrudendo 100mm di filamento misuro 99.9mm col calibro, non mi sembra male

I movimenti sugli assi X/Y, sempre misurati col calibro, fatti 140mm ottengo circa 140mm +-0,05mm..

Non mi sembra malissimo...


Ho scaricato i settaggi dal github della smartrapcore e noto che hanno di molto cambiato max feedrate/acceleration e jerk

questi sarebbero i settaggi forniti con configuration.h che trovo sul sito di smartfriendz

// MOVEMENT SETTINGS
#define HOMING_FEEDRATE {70*60,70*60,10*60,0} // set the homing speeds (mm/min)

// default settings
#define DEFAULT_AXIS_STEPS_PER_UNIT {160,160,200,1476,625,625,625} // X, Y, Z, E0, E1, E2, E3 default steps per unit
#define DEFAULT_MAX_FEEDRATE {500,500,70,50,100,100,100} // X, Y, Z, E0, E1, E2, E3 (mm/sec)
#define DEFAULT_RETRACTION_MAX_FEEDRATE {400,150,150,150} // E0, E1, E2, E3 (mm/sec)
#define DEFAULT_MAX_ACCELERATION {6000,6000,2000,10000,3000,3000,3000} // X, Y, Z, E0, E1, E2, E3 maximum start speed for accelerated moves.

#define DEFAULT_ACCELERATION 1000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 3000 // E max acceleration in mm/s^2 for retracts
#define DEFAULT_TRAVEL_ACCELERATION 3000 // X, Y, Z acceleration in mm/s^2 for travel (non printing) moves

// Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
// The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
// For the other hotends it is their distance from the extruder 0 hotend.
//#define HOTEND_OFFSET_X {0.0, 5.00, 0.0, 0.0} // (in mm) for each extruder, offset of the hotend on the X axis
//#define HOTEND_OFFSET_Y {0.0, 5.00, 0.0, 0.0} // (in mm) for each extruder, offset of the hotend on the Y axis

// The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously)
#define DEFAULT_XYJERK 20 // (mm/sec)
#define DEFAULT_ZJERK 10 // (mm/sec)
#define DEFAULT_EJERK 5 // (mm/sec)

Stasera li provo.
