Help needed, new to cnc and having cut depth issues
Hi all, I am new to CNC and the forum. I have recently built an Ooznest workbee CNC 1500 x 1500 and I've fitted a spoiler board and when I have come to surface it, i have run into the issue of the router coming down but not enough to reach/cut the spoilerboard. I am on Vcarve pro and I have set the cut depth to 0.3 mm and the start depth to 0 mm. 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.
Thanks.

Which software do you use?

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.

You say 0.3. Don't you mean - 0.3 (negative)? As in below zero.

Vectric doesn't require you to type the negative, you just enter the depth as a positive number and it converts it to negative when it posts..!! . . . Which does raise the question.?
Are you using the right post processor for your controller.?

Two questions:does the operation simulate correctly in Vcarve?Does the Gcode output from the example in post#8 include the description G01 Z-4.35?

Yes it simulates correctly it’s how one checks to make sure programming mistakes.
Yes that’s why I posted a picture because it says depth so no minus needed, but it post out g1 z-4.35

Which leads to two possibilities;either the Z datum is incorrect or the machine does not have sufficient travel.If you use the process described by JazzCNC in post #4 it should do the job.Do you understand how to change the Z datum for the progam?

I think you are having a conversation with the wrong person, Dean isn't the OP, I think you have got crossed wires.!
Re: Help needed, new to cnc and having cut depth issues
Yeah nothing wrong with mine I was just showing a picture of the process for the OP as sometimes pictures are easier to understand [emoji106]
