Other CAM programs or files for 3D carvings

Thanks Greg, I'll do just that.

Unwanted lines occurred due to grayscale file processed in ArtCAM.
3D grayscale frame files saved from ArtCAM might create extra lines on workpiece.
We’ve discussed this issue with ArtCAM Solution.
For now, one way to avoid unwanted lines is convert files from i-Picutre.

I get the same problem with some cuts.
I had an issue with a line running down the middle of each cut, it was a hair off on either side as well.
I found it to happen mainly when slow cutting.
Multiple lines I think are from how I-Picture processes certain images. Either the software "sees" something the eye doesn't, something is running in the background slightly glitching processor time, or the file itself is processed in a format which creates bugs. Say 32 bit instead of 8, for example.
Or, there could be power fluctuations during the cut itself. Just enough to throw off a line or two.
Or, there is a bug in the firmware, or hardware, that reads off at times.
Just too many variables with almost no way to test and verify. Each machine runs somewhere with a different setup. Everything from power to image processing differs from person to person. So you can't take an image that cuts perfectly for one person and expect it to cut the exact same way for someone else. Even circuit boards vary with production.
The best you can do is find an image and keep manipulating it until it cuts to the standard you want.

Here is the reply I received via email from Oliver.
"Thank you for sending me the files.

According to our engineer and the iPIcture developer, those lines usually occures when carving frame category grayscale files (those images that have a frame). On other images, the line problem doesn’t appear on images. They are currently trying to figure out why it causes this problem, and they will keep you posted.

Thank you for your understanding!"

Here is a .jpg file that I created using one of the picture frames provided on the thumb drive when I bought the CNC machine.

I used a .bmp in my project but converted it to a .jpg due to the file upload size limit on this forum.

The image size is 10.373 x 13.361

I imported it into iPicture & used the following settings

10.373 x 13.36 x .3
Scan Step 0.015748 (.4 mm)
Tool Type GVee-R 1/50"
Feed Depth 1.0

Workpiece Size 11 1/4" x 14 5/16" x 1"

I ran the spindle around the Border & it was fine staying about 1/2" from the edge of the perimeter of the wood.

Here is the outcome. I watched the spindle go well past the edge of the board (approximately 1") on the right side. As you can see the left side is "skewed" in towards the center of the board & the right side is "skewed" away from the center of the board.

I have no idea what could have caused this or what to do about it.

Any feedback is appreciated.

Also might want to look at the scan step, and use the default .2 the 1/50" bit is .508 mm, so a scan step of .4 is almost the diameter of the tip of the bit, that's why you see those lines in the carve. Or could be a power fluctuation, especially if some one turns something on that is on the same circuit.
