it often leaves a deeper cut (usually just on the first path after a move) that is often very noticeable and difficult to remove
If you examine the machine code your will see that Cut3D is not telling the machine to cut deeper on the first pass.
Example G Code
- Code: Select all
For a raster toolpath unless you are machining objects like circles or squares there will be spots where the machine has to lift the bit and move to another area.
Look at the sample leaf for an example.
What you are seeing is likely due to material movement and/or bit/machine deflection.
A roughing pass will help.
Using the shortest possible bit will help.
Ensuring that everything on the CNC machine is tight will help.
