Your exact setup will vary depending on a few factors, but here are some good starting values taken from this thread on the Shapeoko forum
$0=43.740 (x, step/mm) $1=43.740 (y, step/mm) $2=640.000 (z, step/mm) $3=30 (step pulse, usec) $4=1000.000 (default feed, mm/min) $5=1000.000 (default seek, mm/min) $6=160 (step port invert mask, int:10100000) $7=25 (step idle delay, msec) $8=25.000 (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)
The following are all really questions for grbl, not grblShield, but in an effort to make this easier we also answer some questions here or refer you to the grbl wiki
