j'utilise une arduino oui avec grbl 0.9
mes moteurs ont 4 fils
paramètre grbl
$0 10 (step pulse, usec)
$1 25 (step idle delay, msec)
$2 0 (step port invert mask:00000000)
$3 0 (dir port invert mask:00000000)
$4 0 (step enable invert, bool)
$5 0 (limit pins invert, bool)
$6 0 (probe pin invert, bool)
$10 3 (status report mask:00000011)
$11 0.020 (junction deviation, mm)
$12 0.002 (arc tolerance, mm)
$13 0 (report inches, bool)
$20 0 (soft limits, bool)
$21 0 (hard limits, bool)
$22 0 (homing cycle, bool)
$23 0 (homing dir invert mask:00000000)
$24 50.000 (homing feed, mm/min)
$25 1000.000 (homing seek, mm/min)
$26 250 (homing debounce, msec)
$27 1.000 (homing pull-off, mm)
$100 80.000 (x, step/mm)
$101 80.000 (y, step/mm)
$102 80.000 (z, step/mm)
$110 1000.000 (x max rate, mm/min)
$111 1000.000 (y max rate, mm/min)
$112 1000.000 (z max rate, mm/min)
$120 250.000 (x accel, mm/sec^2)
$121 250.000 (y accel, mm/sec^2)
$122 250.000 (z accel, mm/sec^2)
$130 1000.000 (x max travel, mm)
$131 1000.000 (y max travel, mm)
$132 1000.000 (z max travel, mm)
même en modifiant le potar sur les drivers rien ne s’améliore
