Hey guys,

I’d like to know how to INVERT the direction on just my Y-Axis and my Z-Axis.

My X-Axis is correct. Left goes LEFT and Right goes RIGHT.
Unfortunately my Y-Axis (-) goes AWAY from me and (+) comes towards me.
My Z-Axis (-) goes UP and (+) goes DOWN.

Everything else I’ve managed to correct and re-calibrate through other posts on this site. So BIG THANKS to you legends.

Below are my current settings.

        $$
        $0=132.978 (x, step/mm)
        $1=132.978 (y, step/mm)
        $2=132.978 (z, step/mm)
        $3=10 (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)
        ok

Your feedback is greatly appreciated! Thanks again!
