    So with covid supply chain issues there isnt a sheet of half inch MDF within 100 miles of me for a spoil board for the 1515 i just ordered.

    Can a guy use 3/4 inch instead?

    Yes, you can. You loose a little Z height - but thicker = more rigid so actually better. Or even use Ply, or some other sheetstock instead of MDF if MDF becomes hard to obtain

    hi there
    any one know what some times the cnc goes -10mm in Z axis at rapid movement only before cutting the G codes?
    i`m using Fusion 360 for G-codes

    If you mean it goes to - 10 and you are using the Openbuilds post processor for Fusion that is correct - it's a safety move to raise Z to avoid hitting any clamps when it moves to the point where it will start cutting.
