Cutting a .dxf from a usb flash drive

Can anyone tell me what I’m doing wrong? I have uploaded a .dxf drawing on a usb drive. The Screen shows slots correctly in the pattern, but when I run the cut, 3 out 4 slots have 1 end flat instead of rounded. Please help!!!

That’s a glitch in the kerf algorithm

Remember dxf is a 45 year old format with a lot of patches and kludges and updates
So we keep finding edge cases like this that break the math so constantly updating.

So make sure your Simple Trace is up to date.

We in fact have another update coming out later this week with some maintenance upgrades
