First real effort to make a 3d sign all paths look good in simulation. 3d clipart is from Vectric, I am using Laguna IQ HHC and saving the post files as .MMG. the tool path for my first file "ROUGHING " starts ok but at somewhere about 10% into the routine the CNC loses its position. I have reset the machine a couple of times and it continues to happen. I did make a small 3d sign before I upgraded Vcarve not sure if there are any known issues with the code for the LAGUNA as I said it is probably user error I just can't figure out where. Most of my CNC work has been done using Rhino5 I have not noticed and oddities there.. Thanks in advance for any thoughts and or assistance I have uploaded the CRV file as well as the post files
