In this Q&A session, we discussed different machining strategies, including two-sided, four-sided, and rotary machining. We also covered computer hardware recommendations for running VCarve efficiently, strategies for moving start locations in pocket toolpaths, and how to improve cut quality in walnut. Additionally, we touched on troubleshooting issues with file sharing and VCarve’s drilling toolpath behavior.

Key Tips Learned in this Q&A:

• Two-Sided vs. Four-Sided Machining: Two-sided machining tends to be more reliable than four-sided, which can introduce alignment issues on the third and fourth sides.
• Computer Requirements for VCarve: When selecting a new computer, prioritize screen size, processor speed, and RAM for smooth operation.
• Moving the Start Location in Pocket Toolpaths: The start position in a pocket toolpath is determined by the software’s logic and cannot be manually repositioned.
• Cutting Walnut Cleanly: Even with a brand-new bit, material properties can impact cut quality. Using a ramp plunge move can help reduce tear-out.
• Drilling Toolpath Feed Rate: VCarve does not allow setting a feed rate for the drilling toolpath, as it relies on rapid movement between drill locations.

Questions Answered in this Q&A:

• 00:03:09 - How do I set up two-sided machining for a bowl?​ 
• 00:05:04 - How can I ensure the full shape of a two-sided project is captured?​ 
• 00:16:55 - Why does Vectric list a feed rate for drilling toolpaths when it’s not used?
• 00:22:47 - Can VCarve Pro create a Turner's Mallet using separate molding toolpaths for the handle and head, either with layers or separate sheets?
• 00:24:50 - Can you review my CRV file for a wavy flag model, specifically addressing issues with the wave shape, layer usage, raising white stripes, and adding draft to the eagle and stars?
• 00:29:15 - How do I eliminate corner fuzz when cleaning up pocket cuts in VCarve Pro, and why doesn't moving the start node change the toolpath start point?
• 00:34:08 - Can I move the start point of a pocket toolpath to the center?​ 
• 00:38:10 - How can I improve cuts when working with walnut?​ ​
