Single line Text

Why does the bit of the router pick up the width of the bit at the end of the letter? The single line text is not working, so the letters are short the width of the router bit? Any ideas?

Would need to see the code to see exactly what you're talking about. Can you post the V-Carve file so we can look at it?

Attached is a photo of the problem we are having...any ideas?

Hi - can you post your VCarve project file? Picture was good to show the condition, fooling with your project may provide you an answer - and learning for the rest of us who may not have tried this yet...

Thanks

Here is the file.....

Well I can't read the file because I now use Aspire and it won't view it.

Looking at your picture this looks similiar to a problem I had with the bit not going all the way along some vectors. The fix was to change the path mode in the G-Code. By default its set at .1 inch. This means the machine will try to get within .1" of the actual path while trying to maintain smooth motion. .1" is a lot in my opinion but so far I've only run into a couple times where it was a problem. You might try it. Here's what you do:

1. Open the .TAP file you created with V-Carve Pro using notepad
2. Find the line that reads, "G64 P.1"
3. Change it to read, "G64 P.001"
4. Save the file.

If you want to set the precision permanently you have to do the following:
1. Open the post processor file you are using with notepad. CNCShark-USB_Arcs_inch.pp or something similiar
2. Find the line in the "Begin Header" Section that reads, "G64 P.1"
3. Change it to read, "G64 P.001"
4. Save the file.

This is what I have done since it changes it for everything by default.

This forces the Shark to go as close as it can to the exact spot you wanted it to go. You can also change the line to be "G61" which is exact path mode but the machine tends to jerk a lot depending on what your cutting. Here's a quick reference to G-Code:

Note not all the commands work with the Shark

Hope that helps,

Thanks Paul, it certainly helped me, and I'm guessing a few others...

Cheers
