"hysteresis" in engraving (?)
Added by leenvw about 10 years ago
I've been playing a lot with the laser since july last year. However, I'm picking it up to solve some difficuties I have.
When engraving, for example a square, the picture is tilting. Like there is hysteresis in the x-axe. When engraving a square, the result is a trapeze, see picture.
Also the dimension is a bit out of range: approximately 8%larger
Did somone also deal with this and did you solve that?

What are the settings (config file) and drawing you used for this, along with the software versions (firmware and PC software)?

Hi Peter, Tanks for you response.
The drawing I used was drawn upin Inkskape, however, the samen happens when using Illustrator. For the laser I use Visicut 1.3.4.
In the attached file you'll fing the config-file: may 20 2012.
Hope you can find the clou.

Just to make sure the problem is not in the mechanics, you may want to lower this setting:
motion.accel 500 ; linear acceleration [mm/sec2]
to something like 100 or so for testing.
If the slider is too heavy or has too much resistance, a very high value here may let you loose some steps on the steppers...

Thanks to Jaap and Peter the issue is solved. The value x.invert in the config flie was "-1" and changed to "1".
