General Mach Discussion / pocketing and profiling

« on: October 17, 2015, 09:27:12 PM »

I'm going to try inlay on my cheap 3020 mill, starting with a 1" circle, pocket no problem, profile is either to big or to small, I can get them the exact same size, but need a little clearance to fit properly, I know I can make adjustment by changing profile a little smaller, but when I import designs it wont be that easy.  I know I will have to mirror the image before I run the profile but I think they will end up the same exact size which I could hammer in and make fit but the inlay will be to fragile to do that without breaking. I use bob cad/cam.  any help would be really awesome!

G-Code, CAD, and CAM discussions / pocketing and profiling

Hello, going to try my hand at inlay done on my cheap china mill.  first,  just doing a 1" circle, make a pocket, simple enough, then a profile to fit into the pocket, here's where it all goes wrong, it's either to big or to small to fit.  now I can change the size of the circle, I'm sure, but that wont work on an imported design, which is where I'm heading.  need to make one fit in the other with a perfect fit.  I have been able to get it so both are exactly the same size, but they wont fit together without some clearance, just don't know how to get the clearance!

 Thanks for any help

General Mach Discussion / cant see the part in the toolpath window

Hello, new to cnc, when I watch the video's I can see the road runner drawing loaded and I can see it in the window, when I load it, its the size of a pinhead.  I can use the mouse wheel to zoom, but that takes an hour and it never really gets to the size I want to see.  The same thing happens when I create my own drawing? I can start the program and it runs, but the mill never moves more than an inch if even that. my spindle motor is not working yet, so I'm just trying to do test runs, just set it up, think its a bad board, hope it does not take long to fix!
