V Carve toolpath error?

[killersoundz]

Cutting a Vcarve toolpath on this letter B. I first thought the machine had skipped steps so I stopped it and checked by homing it. did not skip any steps but I repeated it from scratch again and got the same result. aspire toolpath preview doesn't show these lines. please note I have been engraving other things (not this deep however) with no issue with the same vcarve toolpath option

If the toolpath preview looks good then the problem probably lies elsewhere, have you checked both the angle & the diameter of your V bit to confirm it is set up correctly in the tool database ?

Would it be possible for you to post the CRV3D file & the gcode file

It's a .75" 90 degree v bit. I measured it with calipers just now and it's right on. here's the aspire file. The rest of the vcarve in the toolpath ran perfect

That looks like a flex issue with the machine to me. The areas show different loading on the tool. Check that everything is tight and there is no slop.
