I ran a simple v carving and noticed that there were some ridges at the corners of a a letter.
I've attached the .crv file and a photo.
This is very consistent when there is a flat depth on the letter.
I originally thought that it must be a vectric issue and sent them a email, but the say the if the preview is good, then it's not a vcarve issue, it's probbaly the bit. This is very consistent with 4 different 90 degree vbits, so I don't think it's a bit issue.
That leaves the hhc or my machine. I've got the A11 controller. Slowing down the feed rate doesn't make any difference.
It happens when there is that curved path at the corners.
If there is no flat depth, the carving is fine, but it carves a straight line there, not the curved line.
I'm out of ideas at this point, any suggestions would be appreciated.
So, to review the issue and the fix, 1. Was it the software that caused the issue ?
A comparison of the G-Code ( climb vs conventional ) may shed some light on that.
2. Is it a machine issue?
Backlash or lack of tight tolerances.
3. Is it a material issue ? The material moved under the strain of the cutter.
But the real question would be to see if you ran the file again, after the first toolpath, while the materiel was still secured to the machine, would the new toolpath remove the ridge. Or is that cutting another beautiful piece of firewood ?
