Negative skirt ?


Recommended Posts

Posted · Negative skirt ?

Just noticed that Cura when slicing big models (190mm x 190mm), generates negative coordinates for the skirt, this results in the Z cooridinate not being set and the first layer printed "in the air"

Simpel fix is of cause just to edit the .gcode file and change the negative X value to 0.

Is this on purpose ?

    Those moves are outside of the machine, so the print you are trying to make is larger then the machine, which is causing your problems. You can reduce the skirt distance, or disable the skirt.

    I am having the issue that the skirt seems to extrude too much. The print itself prints at the right thickness, but the skirt just oozes out. This wouldn't be a problem if on the second round of the skirt the extruder didn't strip itself trying to print on this thick layer. I noticed that the small herringbone gear that I have was tightened too tight and that the nut is pulling through the plastic, so I ordered a set of spur gears from shapeways. But I don't think that is the main problem, I think it is somewhere in the settings.
