Hi, I have been given a nema17 stepper with a 64:1 gearbox attached.
I have modified and made a 'replicator 2 simple extruder' to fit on the end and all looks good. (pics attached)
My original configuration.h looks like this.
#define DEFAULT_AXIS_STEPS_PER_UNIT {98.52216748768474, 98.52216748768474, 98.52216748768474,
134.76645233}
#define DEFAULT_MAX_FEEDRATE {600, 600, 600, 100} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {1200, 1200, 1200, 300} // X, Y, Z, E maximum start speed for accelerated moves.
I assume I need to increase the 134.76645233 value by a factor of 64?
However, when I try to do this values over 3000 result in just vibration.
Have I maxed-out the stepper controllers?
At 3000 steps I am only getting about 17mm for 50mm demand.
Is this ratio too high.
TIA
