For both of you, @MetalwoodMFG and @TheWoodSamaritan .
Step-by-step write down each step you take after the machine’s initialization / homing routine. Write down the words from the screen prompts, too.
From you’re posts, we’re assuming that you both have the BitZero and BitSetter devices properly installed, but check this in your machine settings. If you don’t, nothing said here will make any sense.
Be sure to indicate the location of the BitZero including whether it is completely on top of the part or hanging over the edge of the part.
Indicate whether you use a bit for the XYZ procedure or whether you use a machined dowel and what size.
If you have the newer version 2 of BitZero, does it move during the operation?
Each step can then be evaluated in order, but remember the old saying, “Garbage in; garbage out”.
