I thought I had seen it in a past release notes or thread but my search-fu isn’t working well at the moment.
When doing a pocket, was there a formula for setting the max depth to “use stock bottom” + a measurement. IE - If am cutting boxes and the stock varies slightly, I always want the bottom of the pocket to end .25" before cutting through the piece.
Can I do something in carbide like:
Max Depth (D) = t + .25
“t” should recalculate the depth of the stock with each zero?
Yes, except you want t-.25 (assuming the default measurement in the project is inches).
If you are zeroing top-of-stock, you will also need to set an accurate Project Thickness for each piece, and resave in CC and reload in CM.
Depending on what other toolpaths you have, you may find it convenient to simply set the Stock Depth to that of thickest piece of stock, and use Zero from Bottom. In that case, you would not have to keep updating the Stock Thickness, since the only repercussion is that you first passes may not take as much material as the DOC suggests. HOWEVER, this only make sense if you DON’T have any toolpaths that are defined relative to the top surface.
I always wind up with scraps that are a couple inches long, so I figured I’d just set up a sliding box project like POV CNC created and turn them into useful little stocking stuffers. That’s a really good idea to do all the toolpaths from the bottom up for this. It will allow me to create several CC files for making the boxes - ie project A is for stock that’s 1.5-1.6" , project B for 1.6-1.7", etc, etc…
Sure it may make a pass taking nothing off, but saves me from having to drag the planer out and shave all my stock down or constantly changing and updating the project.
