Laser engraving problems with inkscape

edited May 2019 in Repetier-Server
Okay, So I have been using the Repetier plugin for inkscape to laser etch things, but I cannot get the gcode to work properly with the server/firmware.
It seems to generate correctly in Inkscape, but when it loads into repetier it gives me a few lines out of all of it and when I try to print it, the printer gives the error, "18:50:43.207 : Error:No move in delta segment with > 1 segment. This should never happen and may cause a problem!" Any ideas.


  • Yes that is a case that should not happen:

    int32_t virtualAxisSteps = static_cast<int32_t>(maxStepsPerSegment) * segmentsPerLine;
    if (virtualAxisSteps == 0 && p->delta[E_AXIS] == 0) {
    if (numLines != 1) {
    return false; // Line too short in low precision area

    You managed to get 0 virtual steps in a segment for a line that was long enough to be split. There is a check to rule out a 0 move caused by tiny distances in latest dev version. So first I#d upgrade to latest dev version of firmware to check if that message still appears. Might be exactly the case we no cover. Not sure how else you could create a move causing the error message.
  • I tried updating everything, but I still have the problem, I think the problem lies within the gcode from the repetier plugin for inkscape. Any ideas?
  • OKAY, another clue! It only has this trouble on curves. The straight lines 'slice' no problem.
  • Ok curves get subdivided in lines which are of course quite small. What are your steps per mm and updates per second? Can you also post the gcode. Maybe I can recreate it once my delta is working again.
  • edited May 2019
    OKAY here is the Gcode. I would think that my steps per mm would be irrelevant to this as the problem seems to occur before it even reaches the repetier firmware in the arduino. Just try loading it into repetier and see what it generates.

    This is suppose to say HELLO WORLD, but its all messed up.

  • >  I would think that my steps per mm would be irrelevant to this as the problem seems to occur before it even reaches the repetier firmware in the arduino.
    No that is wrong. The message comes from the printer and depends on a case where no steps are so step resolution can be the important hint, which is why I asked for it.
