Printing problem after a factory reset

[paul9 20]

Today I did a factory reset and after that I started to have the following problems.

The printer creates problems after printing the first layer.

The subsequent layers of filling are all detached one with each other.

I tried to lower the current values of the stepper motors first to 1100 mA and then to 1000mA but nothing changed.

Where is the problem?

Do you use a different extruder than the original one?

Then you need to adjust the steps/mm.

There are many things that go back to "default" when you do a factory reset including all the steps/mm settings. Particularly, like conny_g, I'm guessing you messed around with Z steps/mm long ago? Does that sound possible?

Alternatively it could be the extruder steps/mm.

I would calibrate both. Move the Z some distance such as 100mm and then check that it moved the correct amount. Repeat with the extruder.
