If you want to activate a work-offset on the machine from DMIS, you may use the pass-through function. There is an easier way to do that. 

  1. Open CNC->Workoffsets feedback
  2. Choose Use Work Offset in program
  3. Select the work-offset you want to activate
  4. If there is a work-offset alignment corresponding to the work-offset, select it
  5. Click ok. This will insert the required DMIS to activate the workoffset on the machine, and in CappsNC (if you select a corresponding alignment)
