A related question is how do you hold down your PCB, and where/how do you set your height zero? Is it possible that whatever would be 0.07mm deep wherever you originally set it is actually a lot deeper where you do the milling? Because there is no such thing as a "flat" mill table when PCB milling is involved...

    This is not stupid question at all. But yes, tool is intact and works fine. Manage get better results when I use in Flatcam tool width 0.45mm. Tool is fine and I checked with new tool, no difference. Small edit. If the tip of the tool snap off after you start milling and because I use auto level option, It would not mill at all because its moving above pcb surface...

    I hold PCBs down with hard double sided tape.

    I set Z to zero first getting it near as I can to the pcb and I run Auto level with chilipepper software. That put zero exactly on surfice of the pcb...

    Hi Miki,

    Let me point you to a site with member's using exactly your CNC machine for help.

    https://github.com/martin2250/OpenCNCPilot

    https://github.com/martin2250/OpenCNCPilot/issues/28

    Hope that site should resolve your issues.

    Cheers,
    Hanspeter.
