I have a question about some issues I’m encountering when making cuts on the top or bottom of a PCB. For example, when I need to run two cuts on either side, I can't run the probing twice because some regions become isolated from the spindle, preventing surface detection. I need to adjust both G-code files—one for the PCB layout and the other for the border.
The issue is that after running a job on either side, I'm unable to use the PFG file to probe the surface with the CNC machine. This happens because the first job isolates the PCB, and zero detection fails since there’s no longer a copper connection between the spindle and the PCB.
I’ve tried using Autoleveller twice with the same file generated by my CNC, but it doesn’t seem to work correctly, and the jog speed isn’t being factored in.
My idea is to take a screenshot of the Autoleveller to save the mesh coordinates, then open another instance of Autoleveller, manually input the mesh coordinates, and load the first PFG measurement along with the new G-code to apply Autoleveller corrections. After that, I would generate a second job (the second Autoleveller-corrected file).
Also, why does Autoleveller display this message, and is there a way to adjust the maximum segment?
