The Z should start to move down towards thematerial. If it moves in the wrong direction STOP the move and use the CONFIGHOMING/LIMITS in MACH to change the polarity of the Home Neg value.

When the Torch Tip hits the metal the Z will continue to move down until it trips theswitch. The Z should stop and reverse slightly. Use the Z Zero Button (next to the Z DRO) and reset the Z DRO to 0.000.You may want to lower your Jog % in the Diagnostics Tab to 10% or less to slowdown the manual jog rate. Carefully jog the Z up using the keyboard hotkey (default isPage Up Key) until you can slip a piece of paper under the torch tip. Perform the move again and confirm the value. Once you have several readingswithin .005 then write down the Z DRO reading The value you have is the Net Switch Offset and will be used in either MACH OR inSHEETCAM (post) but NOT BOTH.PAGE 28
