1-23-2024 Q&A: Optimizing Z Feedrate with Ramping in CNC, Managing Merged Toolpaths, Importing and Creating STL Files, Vectors Not Recognized, and Model vs. Machined Output

This Q&A Meetup dives into optimizing CNC projects, from tweaking Z feed rates for smoother machining to resolving Vectric toolpath issues. Attendees learned about importing and creating STL files, troubleshooting vector visibility, and refining cribbage board cuts. The discussion also covered practical solutions for common CNC challenges, making it a must-watch for those looking to improve their project outcomes with technical insights and software tips.

Question Answered in this Q&A:

• 00:02:09 - Used the general theory of using a Z feedrate of half of his X and Y feed rates, after watching some of your live lessons, you have got me thinking about using the ramp for the Z feed. It would seem to me that if you use the ramp, you could have the Z rate the same as the X and Y feed rate. What do you think of that?
• 00:05:32 - Created a merged toolpath in his project, and then saved and closed the project. When he reopened the project, one of the toolpaths was no longer in the group. I put it in, and now I can't find a way to put it back where it belongs. Is this possible?
• 00:11:56 - Can you do a quick run through on how to import and create an STL file from import to toolpaths?
• 00:25:06 - Having a problem with Vectric not seeing vectors from a vector download in FreePic.
• 00:27:06 - In making a cribbage board the roughing cut is running the outside of the finish cut, wondering what setting I messed up on.
• 00:49:25 - This is the model just what I want. However, what gets machined is not what I see.
