Thread: BobCad Chamfering help
-
18-08-2012 #1
Hey guys, I have watched as many tutorials on BobCad as i can find, however I cannot find one on the chamfering, i am struggling with its positioning and understanding how it all works.
Now I have played with it but always seem to get bad results, even crashed my machine a couple of times.
Could any one please explain how to do it.
To note, my positioning / Zeroing is perfect, as i managed to 'fluke it' once and get one chamfer cut perfect but since, I cannot get it right...
So rather than me guessing could someone please explain the best way to go about it please? Or better yet a point to a good tutorial?
Thanks

Hello Craig,
Yes I can help you! So you are having problems with using the chamfering feature, I have some questions for you.
1) What version of BobCAD are you using?
2) Are you using a sharp bottom tool or Flat bottom tool?
3) When you say you had a crash what happened?
4) Can you share a drawing file and or the parameters you used when you had the issue?

* The above code is based on all the same settings except the cutter position is now set to .05
What you'll notice is the greater the cutter position is the the deeper in Z the tool will go.Al DePoalo

This video shows with no sound ( sorry) why the tool will cutter deeper in Z when you adjust the cutter position.Last edited by aldepoalo; 20-08-2012 at 03:10 PM.

Thank you for getting back, I think I had an error in my installation.
On my laptop I created the tool path 3 times and had the same issue of it plunging randomly about 10mm away from the chamfer (almost like Bobcad had a bigger tool than I told it)
Then I came to my other PC and I did EXACTLY the same path, and it works perfect.
Since I reinstalled BobCad and it all works okay now.
Thanks for the help
