60mm at 1200mm/min is 0.05 min or 3 seconds.

Lightburn (G-code) is calling for the 1200mm/min. Is the engraver still moving abnormally fast? Can you measure that square and make sure that’s really close?

24

without the tabs it took 3 sec and is dead on 60 mm. with tabs it takes about 2.3 sec and is still dead on at 60 mm with tabs it went at the 1200 mm/m until the tab the speed up to the corner

25

do you mean… “then sped up to the corner (after the tab)?”
is it slowing down to make the tabs?

26

yes hits the tab then speeds up until the corner

27

Try this:
Draw three short straight lines, in a row, 10mm long each, with about 50mm of gap in between them. Set the line speed relatively slow, like 500mm/min, and the laser power at 0.5% so it won’t burn anything.

Run that. If it finishes the first line, speeds up, and stays fast for the 2nd and 3rd lines, it’s a bug in the firmware, not LightBurn.

28

I did what u asked the first and second went slow and the third wend fast

29

I would submit that to XTool - they have a bug in their firmware. (I have also reached out to them, but haven’t heard back)

This might be important for your conversation with Xtool.
