I have started to print the test structures from Make:
That shows different problems of my printer.
The gantry is not perpendicular to the X-Axis which I see in the print and also looking from above. The Z-Pillar seems do be quite ok. So it is probably the guides of the gantry on the Z-Pillar.
Is there a recommended way to correct this?
The Z-Axis wobbling test shows a sine wave of the tower in Z direction especially on lower layers.
What does this mean?
