Help! cura generates negotive value for X&Y coordinates

Posted · Help! cura generates negotive value for X&Y coordinates

Today, I found cura generates negative value for X&Y coordinates, which caused dislocation print. But I try to addjust the parameter of machine setting to solve it, but failed.

"to release some of the pressure
G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more"

or 

"G0 X-0.9 Y-57"   it's seems the offset of extruder 2.

 

What should I do to fix it.

    In machine settings uncheck the box that says "origin at center".  That is for delta machines.  I don't think you have a delta machine.

     

    That will make all the X, Y and Z values >= 0.

    Thinks for your reply. But I confirmed that the box " origin at center" is unchecked.    This occures only when slice with dual extruders.

    That sounds like you are printing too close to the edge of the printable area. IIRC, there are settings in the printer profile that specify the acceptable bounds for printing. When printing with two nozzles, you need to make sure that the left and right edges of the printable volume are constrained so that both nozzles can reach it.

    Thanks. It is solved. This is due to the default direction setting of relative coordinats of the second nozzle.
