Hello again,

just have a look to LazyCam:

1. You can turn the work object by pressing the center button (Wheel) of the mouse, to look to the drawing sidewise in 3D.
   This is where you can already see how the toolpath will look like.

2. But now, lets look NUMBERS:
   - have a look on the left side fo the screen: There you can see the tree of layers in your workpiece.
   - activate Layer 0 by doing a click to it.
   - Now, click "layers" in the menu at the bottom side of the LazyCam Window.
   - Here, you can see:
      Step per pass: 0.1250 units
      Cut Start: 0.1000 units
      Cut depth: -0.1250 units
   - this will generate a G-code which does -0.0250 (=0.1 minus 0.125), and the the rest of 0.1 to get to -0.125.


Hopefully this helps.


best regards,
Konrad

Nicolas,
Have you taken a look at the LC Manual?

Yes RICH I did read the manual but as a beginner things are not always pretty clear.

I know that I’m doing something wrong and if I knew what it is I would have gone to the manual to get the fix. Unfortunately I don’t know what I’m doing wrong and reading thru the manual can get pretty confusing.

I understand what Konrad is saying but all I know is that before I used to follow the same steps and my code was everywhere Z-0.125. I don’t remember seen any -0.0250 in my code. Perhaps I was using for “Cut start” 0.0000 instead of 0.1000. I will try this and see what it will happen

On top of that, the “Boss” decided to do some remodelling in the house and she wants that done before X-mas otherwise I will loose my tools allowance. So this extra work does not give me enough time with my CNC to resolve the problem. Hopefully I will finish the remodelling job soon enough before I forget even how to turn ON the bloody CNC lol

Hi Nicolas,

I would recommend to take much time for optimizing the mill, and the produce lots of nice (and useless) accessories for the remodelling of the house ::)

Yes, yes, Konrad has spoken words of great wisdom. Can make all knids of stuff for the remodel job.  ;D

Nicolas,
The best thing you can do is read through the first 30 pages of the manual as that basicaly defines all the tools , menus, etc.
More important is to go through each tutorial and follow them. The fisrt tutorial is key and then the others build on it. Make note of how the cut depths are done.
Don't hack your way through the program.
RICH

BTW, Work before play  >:D

I had the chance this morning to give another go on my CNC but again I have the same problem but its worst. Although my depth of cut is set at -0.0625” the bit eventually will go thru my stock

On file Tulip2.tap, by the time the code reached line N560, the bit went thru the ½” MDF

On file Tulip22.tap, by the time the code reached line N120, the bit went thru the ½” MDF

I can’t find in the manual anything to fix this problem. Any help?

When it goes through the stock, what does the Z axis DRO show? The code only says to go down .0625, so it sounds like a mechanical problem.
