How can I improve the cut quality when working with difficult materials and/or deep v-carvings?
When cutting hard materials or very deep v-carvings the tool may vibrate or chatter causing marks on the job.
A tip for improving the surface finish is to:
1. Calculate the toolpath using multiple Z Level passes
2. On your machine - Set the Z Zero position for the tool slightly high (i.e. 0.02" or 0.5mm) and run toolpath 1. (this will leave material on the job)
3. Calculate a second toolpath that cuts the job in a single pass (Be sure to set Pass Depth greater than the actual Min Z depth displayed for toolpath 1
4. On the machine - Set the Z Zero position correctly and run toolpath 2. This toolpath will remove the remaining 0.02" / 0.5mm cleaning-up the surface finish.
