Geeetech

Hello,

My X and Y axes are not perpendicular. I tried to mechanically adjust it, but the Geometry (parallelograms) is not very suitable to do so. Before I start drilling and milling, I would like to ask:

1) How do you effectively adjust the perpendicularity mechanically?
2) Is there a software ...

Hello,

I have a Geeetech i3 pro b, and the X and Y axes are not perpendicular.

I was not successful in correcting it mechanically, because the Geometry (basically parallelograms) is not very suitable for angle corrections.

Before I start drilling and sawing: how do you effectively calibrate the ...

just wanted to give an update (because I dont like those threads with problem descriptions, but finally no solution).

I am 99% sure that the bad PSU plug on the board was the cause for the poor quality. The connection was shaky, and due to vibration, the stepper motors would not work properly ...

It's a Geeetech I3 pro b.

I am unsure concerning the Z-axis. Yes, I kept them greasy. The "underextruding" would mean that the z rises too quickly during the failed layers. Skipped z steps would rather lead to "overextrusion"-symptoms.


I might have found a possible cause: The PSU-Plug to the ...

sorry, fixed it in the OP....

btw, i can exclude:
- filament quality issues
- hot end temperature issues

Hello,

Please have a look at my print (right click - open in new tab):

Initially, for the lower layers, the quality is really good, but then suddenly, at a certain z-height, the print quality is extremely poor, as if it is under-extruding. But then again, the quality is ...
