Has anybody out there run into this…
Here’s the endmill I’m using…
The wood is poplar. Carve function at 0.8mm depth used in ESTLCam.
The belts on the MPCNC are tight. If anything maybe a bit too tight.
Thanks!!
You entered the tool wrong in Estlcam. Something with the tip radius that you can only do with 12 I think. Can you please show us the tool’s settings?

Probably the angle is wrong.
The angle seems to fit, looking at the rest of the carving, but if the round tip is too big in settings it looks like in the picture, because it "pulls up"in the corners to make them sharp.
I’m at work, but I’ll screen shot my tool settings on my lunch break.
Thank you both!
I’ve used this combination before and had very nice results but on larger scale engravings.

Do you have a setting turned on like “overcut” corners? I use CamBam which has this setting. I am not familiar enough to know if there is something similar in EstlCAM
No, I did not designate any overcuts.

The settings look fine to me. Mine looks the same but has 10.1°, but that isn’t it. Can cut upload the E12 please?
Have you verified those numbers (0.5mm, 3.125mm, 15mm) on the bit?
The angle looks right. But if it thought it was skinnier than that, then it would push it too far into the corner without lifting it.
I’ve never used ESTLCAM, but I’ve seen similar things in Fusion360 and it was due to the bottom plane being restricted so that the max depth was too shallow for the taper angle of the tool to have the tool edge meet the edge of the artwork.
Hi @Tokoloshe, do you mean the gcode for the job?
Nah, the Estlcam E12 file. 
You have to zip it first though.
Okay, the code looks perfectly fine. I like that you put up all the pictures of your endmills.
Maybe, and that’s just a guess but it’s basically what was said above: The letters are tiny and I don’t think that EstlCAM can do engravings with a round endmill. I have seen similar things when doing my inlays, if you look at the bike’s pedals you are going to see that it has those dogbones as well (though a little less pronounced) because it pulls up the tip to the edge but treats it like an actual tip (at least what I have seen so far). Broinwood says something about V-Carve doing the same in one of the old videos so he rounds every edge and adds the radius of 0.25mm.
I have an inlay hat I want to test the following days where I did exactly that in some places, but didn’t in others. That should show once and for all whether that’s the problem.

I appreciate the good advice! As an experiment I’m going to open the Inkscape file and change the hard corners to the 0.25mm radius that you referenced. If it work I’ll hit the solution button. It makes complete sense, I think it’ll work…
Thanks Philipp!!

You could also try with one of your 60° endmills. See whether it happens there as well. Just do one letter.
