Using V-carve on a LEAD CNC, and cannot get the toolpath to cut deep enough to free the part from the material. I have no tabs programmed, but it consistently stops .020" from the bottom of the material and I'm not sure what I am doing wrong. The part is a simple dome out of .75" MDF...I have attached the .stl for reference.
Did you measure the actual stock thickness? Advertised/marketed dimensions are for marketing purposes.
the default for most toolpaths in Fusion is to have Axial Stock to Leave, which means it will leave some material off the end of the tool. check that.... and watch this
