Work Z off on finishing pass

first,…total newbie here, first time CNC owner or operator…

Ive tried repeatedly, followed step by step, watched multiple videos, and cannot seem to get my work Z to line up for both passes.

step by step,

  • Setup project in Easel
  • Home Machine (Machine > Home)
  • Click Carve
  • Probe Material to set z-axis work zero position
  • Move to XY work zero position
  • Click Carve
  • When carve stops, change the bit (assume machine has moved)
  • Re-Home Machine (Machine > Home)
  • Click Carve
  • Probe Material with the second bit to set z-axis work zero position
  • USE LAST XY to have the same starting point as the roughing carve
    …and no luck…stuck on this one.
