One problem I have found with 1/8 endmills is how much they flex when cutting. Have you tried cutting the item with a 1/4 inch? That may help...
The shaft may be correct, but the cutters may be slightly smaller. That seems to be the case for the cheap Chinese 3.175mm endmills. At least...
The Uno works fine. The reason why grbl -- using the Uno -- only runs 3 axis and can not do tool changes automatically is because of the lack of...
Is there any chance your endmill is slightly undersized? I measure all of mine with a digital caliper. I have received several from well known...

How did it go up but the picture shows a negative Z coordinate? How did you generate the G code?

@ricklach Is your $21 setting enabled? That is the setting for enabling "hard limits." Grbl v1.1 Configuration [ATTACH] Are you using...
