problems printing straight lines in 45 ° angle

Posted · problems printing straight lines in 45 ° angle

Hey guys,


first time in this forum.


When I started 3D printing many years ago, I bought the cheapest 3D printer I could find (Geeetech Prusa I3 pro W) and started modifying it. Today, it is still the same printer (I use the same electronics and software) but the frame and many other parts of the printer are completely modified. Currently I am studying and do not have the money to buy one of the nice Cura printers.


I found Cura to be the best Slicer software for me so far. However, I am experiencing some compatibility issues once in a while. The trickiest one occured recently:


When I print e.g. a normal rectangle or a plate in a 45 ° angle, sudden angle shifts occur during printing. This happens sporadicly and seems to be connected to the G-Code: If I save the G-Code that caused a shifted model, this G-Code will always produce a shifted model and vice versa.


I found a topic in this forum where a similar issue is adressed:

Here the people come to the conclusion, that it must have something to do with acceleration, that the printer tries to accelerate faster than it physically can, and therefore looses coordinates.


I do not think this is true for my case. I printed additional parts next to the 45 ° shifted rectangle and those were printed perfectly. I would assume, that if the printer lost coordinates, it would affect other parts on the same build plate as well.


I tried activating "acceleration control" and deactivating "relative extrusion" but none helped. I hope there is an option in the slicer settings that solves the problem.


Hope you guys can help.



Kind regards

    Ok, nevermind. I found the solution: Seems the object lost adhesion to the build plate imperceptibly. So everytime the print head went over the object, it was pressed down slightly. The new layer, then, was printed in a deviated angle.


    Increasing the brim width or printing on a raft, solved this problem.
