Make a warmup program with alot of Z moves to go along with the X and Y. Also gradually increase the spindle speed as it runs. Mine takes about 20 min to run and helps quite a bit. Mike

This has happened several times in mc2024. Never happened in mc23 or earlier versions. Mike

I've had it happen several times. Using mc24, installed update 3 last week. It hasn't happened with this update yet.

Material database migration came in corrupted. Tried migration again on just that file, no good. Took mc23 database , converted to text, then mc24 converted from that text, still no good. Finally just copied the mc23 file and dropped into mc24 location and it seems correct. By no good I mean the values were different between the 2 databases. One material came in with a default cutting speed and feed per tooth of zero.I can't trust it right now. I'm doing one off parts, I'll try it in a couple weeks. Mike

I know, it took me 20 minutes to find "bounding box". Hiding it in a right click menu.

What I do is contour the top of the part, use ramp/depth with pass at final depth. Use computer comp, turn off roll around corners and infinite look ahead. For a cutter I use 1/8" 90 deg included chamfermill. Stock to leave at -.0575". This puts the tip .005" inside the contour. Linking depth -.006". Verify and adjust. If some letters are too narrow and are left out, try -.06" stock to leave. Mike

Why is this? It seems to be on older programs.

If you have cad data, you can measure the pilot hole size.

That would work until someone clicks on the tool and resets the depth of cut values.

I'm not saying he did something malicious. All I'm saying is I extracted the file, opened the folder and saw one of the two files disappear. The fixture file was still there and the x+ wasn't. I can't install something that is quarantined.

Norton flagged that with a virus

Ok. Earlier versions never used to do this.

If I start 2017 there is a machine def loaded. File, new = def loaded any mcam file, open = def loaded If I open any other type of file (step, x_t, sldprt) it switches to design and I have to manually add the machine def. It's kind of annoying. What am I missing? Thanks, Mike

I wonder how long Mastercam products will support Win 7 x64. I'm reluctant to upgrade to 10. My boss upgraded my previous computer and I lost the ability to communicate with the cnc machines. Mastercam X6 worked fine. Struggled for 1/2 a day, reverted to win 7 and everything worked immediately.
