When I Ref All (X and Y) to the lower left corner and Z to it's highest point, Mach3 loses this setting after restart.  Am I doing something wrong or is there a SAVE command I'm missing.  At present, I have no home or limit switches activated.

Jeri:  I'm new to CNC and I just installed your 2010 screen set.  When I set my soft limits on Z, how do I calculate the min. max. throw?  Do I put a bit into the router and touch off to the bed or a piece of material?  I'm really confused about figuring these numbers.

Check Persistent DRO's on the Gen. Config page.

Thank you.  I will do that in the morning.
