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 ?

    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.
