    Hi
    I am new in this CNC world,and I just got my machine together and it all looks good.
    I have a little problem...I zero my Z axis to 0....but when I " Run Job" it goes straight up to max and triggers the end stop switch.....Have I overlooked something..?

    How are you generating your job? Somewhere, and I can't for the life of remember where... maybe in your CAM settings or the post process, there's an option about "Safe Z". It's a setting specifying how far to raise the "Z" access before moving to the start position. My guess is that value is too high, and it's raising too much and hitting the end stop.

    - Make sure you entered a Negative number in Start/End of Job Z position field (See the tooltips when hovering over them) in Post Options
    - Make sure you Homed as Fusion uses Machine Coordinates too
    - Above assumes you are using our Post: docs:software:fusion360 [OpenBuilds Documentation] which you should
