Raster engrave skip 'whitespace'

Postby 3d0g » Wed Jul 31, 2019 6:54 pm

Request for a future UCCNC release - skip 'rows' where there's no engraving data. For jobs with lots of text, this would be a real timesaver.

That would seem to be a task that would better be performed before getting to UCCNC. What program are you using to generate the raster? If it could be told to skip whitespace, that would be a plus. If not, you could cobble up something that edits the g-code and removes the raster lines that contain no output . I assume that "output" means a negative Z move. So, if there's a positive X move and Z is not at a cutting depth, just ignore the X move.

Of course, that makes a lot of assumptions, but it's the general idea of how you could do this.

I suspect that the laser engrave plugin within uccnc and developed by cncdrive is what is being referred to here in this post as it outputs directly to uccnc in motion code (not gcode)

Correct. UCCNC does not generate gcode for raster engraving. Hence my feature request.

first time testing laser engrave plugin today.
that would definately be good !
even if it went to rapid speed instead of feed speed in laser off areas?

If they say it can't be done- I find a way!
