General Mach Discussion / How to make soft limits stay on in Mach3

« on: July 24, 2012, 12:09:16 PM »

I am running a CNC router with Mach 3. To prevent step errors from accumulating, I hit "All Home" after each sheet is cut and the program returns home (program home, not hardware home). But here's the problem, I have to hit "All Home" twice each time because the first time turns soft limits off, the second time turns soft limits back on.  Or, I can manually turn the soft limits back on after "All Home" turns them off.  But why turn them off to begin with? It just costs extra steps. If you forget the step and don't turn soft limits back on, then you can crash the limit switches when jogging for setups, tool changes etc. Crashing the limit switches is big trouble on this machine... and its inevitable when soft limits is always toggling off!

Is there no way to make soft limits stay on until you ask them turn off?

Any suggestions would be greatly appreciated!
