I haven’t been able to get my grblShield to move my stepper and I’m not sure where to start. I have looked at the faqs. I wired it to a stepper that is working with my tinyg controller, but I’m getting nothin.
There are 2 pins on the shield that don’t plug into anything? Is this normal?
I have the lastest grbl firmware loaded on my Arduino Uno. I’m able to view and change my setting:
$0=300.000 (x, step/mm)
$1=250.000 (y, step/mm)
$2=250.000 (z, step/mm)
$3=30 (step pulse, usec)
$4=250.000 (default feed, mm/min)
$5=500.000 (default seek, mm/min)
$6=192 (step port invert mask, int:11000000)
$7=25 (step idle delay, msec)
$8=10.000 (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)
This works with or without the shield plugged in.
Thanks,
