Good at straight lines, poor at curved lines
« on: August 17, 2016, 06:46:04 PM »
I'm very new to this laser cutting thing. I about an A5 laser off Gearbest to use for it's cutting feature. I wanted to cut a few images out for cards that I'm preparing. After some trial and error, I got it cutting straight lines fairly well. The laser light is a solid beam, like a hot knife through butter. But when it encounters curves, the laser starts blinking as it cuts (rather than a constant, solid beam). It's as if the curve is interpreted as multiple short lines joined together and the laser has to turn on/off for each segment of the line. As a result, the curved lines don't cut all the way through the card stock. If I reduce the speed, it tends to burn more during the straight lines.

This is what I usually do:
1. Open image in InkScape.
2. Trace bitmap
3. Delete the original bitmap, leaving only the vector.
4. Save as DXF
5. Open DXF file in Benbox
6. Set to cut as Outline, either polyline or curve.

For example, it could cut the letter T out perfectly, but the letter S doesn't cut through the cardstock. Is there any way to fix this in either InkScape or Benbox. Is there other software I could use?

i missed that too, not sure why it's doing that. Try BCL or T2Laser and see if it does the same using a different firmware.

Hi and welcome to the forums!

Do the curves seem to affect the movement as well or just the power of the laser?
