dovrei configurare le impostazioni di GRLB ma non ho capito bene come calcolare i valori.
Esempio:
$0=755.906 (x, step/mm)
$1=755.906 (y, step/mm)
$2=755.906 (z, step/mm)
$3=30 (step pulse, usec)
$4=500.000 (default feed, mm/min)
$5=500.000 (default seek, mm/min)
$6=28 (step port invert mask, int:00011100)
$7=25 (step idle delay, msec)
$8=50.000 (acceleration, mm/sec^2)
$9=0.050 (junction deviation, mm)
$10=0.100 (arc, mm/segment)
$11=25 (n-arc correction, int)
$12=3 (n-decimals, int)
$13=0 (report inches, bool)
$14=1 (auto start, bool)
$15=0 (invert step enable, bool)
$16=0 (hard limits, bool)
$17=0 (homing cycle, bool)
$18=0 (homing dir invert mask, int:00000000)
$19=25.000 (homing feed, mm/min)
$20=250.000 (homing seek, mm/min)
$21=100 (homing debounce, msec)
$22=1.000 (homing pull-off, mm)
Come calcolo i primi 3 valori?
Ho trovato questo:
The mm per revolution of the lead screw
The full steps per revolution of your steppers (typically 200)
The microsteps per step of your controller (typically 1, 2, 4, 8, or 16). Tip: Using high microstep values (e.g 16) can reduce your stepper motor torque, so use the lowest that gives you the desired axes resolution and comfortable running properties.
The steps/mm can then be calculated like this: steps_per_mm = (steps_per_revolution*microsteps)/mm_per_rev
ma non capisco dove trovare ilrevolution of the lead screw.
Grazie in anticipo.
