CNC Shark Forum

I am doing my first project, a simple Ohm symbol using MDF. I have the depth of cut set to .73, which is the material thickness. After bit changes I move the bit to contact the material surface at the X:Y 0:0 location and reset the Z to zero.
I ensured the Z travel will allow the bit to go beyond .73, and halfway through the spoil board, so that is not an issue.
I checked the .tap file and the last cut shows a Z of -0.7300

However, once the file is processed, the cut does not go all the way through, leaving .07" of material.

Other specs:
- H520 with spindle
- 1/4 upcut end mill bit
- machine type is 4003
- Post processor is "Next Wave CNC (inch)(*.tap)
- anything else I should check?

I do also get the message "file not referenced to center" that I have seen elsewhere in posts. I'll continue to check those out for an answer

Any idea why it is not cutting to the specified depth?

Thanks!

For the "file not referenced to center" issue, I found a Virtual Zero option under Apps on the pendant, so I set that to 'No' and the warning message went away

On another post I found that for the H520, the machine should be set to 4004. I'll try that and see if it fixes my issue

Changing the machine to 4004 was not the answer - it actually was worse.

I bumped the depth of cut to .80, and it did cut through in places. While not optimal, and prone to not producing the results I expect, is there anything else I should check?

With the cut not parallel to the board, I will check the gantry to make sure it is at 90 degrees to the board

Any hints or tips would be appreciated!
