M220 Z1/Z2 Synchronized OFF
M220-(M&S)Z1/Z2 Synchronized(Superimpose) OFF
Default Synch OFF during Power UP
Built in Wait code. Program on line by itself in main and sub.
Synch control is reset with reset button, E-stop or Alarm
Found a quirk. Sometimes after the M220 on the sub side we uses a G28W0 to send sub home.
I found that If we were in G1 mode prior to M220, the G28W0 does not work until a G0 is added
after the M220.
