Question about tool setup Estlcam

Hey everyone! I’m trying to get setup in EstlCam for carving, I feel like my mill tooling is setup good but I noticed on the finishing passes after a tool change, that it spent way too much time cutting air and then was off when it went through the tool change and finishing.

I setup two seperate gcode files from the same 0, I made extra sure that nothing moved during the tool change.

At first it was cutting air for so long, so I thought I didn’t put the carving 90 degree bit low enough in the collet. So I lowered it and still nothing changed.

My thinking is I setup the tool wrong in EstlCam, here is my endmill tool:

Here is my carving tool:

Did you update the z0 after changing tools?

I did not, I guess I was confused on if I do it to the surface of the carve or the surface the outside?

Estlcam will assume z0 will remain the same between toolpaths, so you need a plan to manage that, even a piece of scrap the same thickness as your stock material to touch off on.

Do you know if you seperate this here and do a roughing check first then a finishing check, will the 0 need to be at the top of the low point after the roughing, or at the top of the board?

Top of the board

The machine will base everything from the same 0 point, so you need to set 0 at the same place with every tool change.
