Help needed, new to cnc and having cut depth issues

[JAZZCNC]

I have used an xyz touch probe that came with the machine to show it where the spoilerboard surface. I am going mad trying to sort this out so if any CNC wiz can help me figure out this problem it would be greatly appreciated.

I'm assuming the Z-axis and cutter do actually reach the spoil board in terms of the cutter can touch it.?

If so, then I think your problem could be that the height (thickness) of the touch probe is set wrong in the control software so it's telling the controller the surface is higher than it really is.

The easy way to test this is to simply very slowly jog the tool until it just touches the surface and then ZERO from this point.
