How to perform a normal printing operation

[dcfdleeg-del]

I have tried many times, and I can guarantee that the nozzle I adjusted is at the right distance from the base plate. However, every time I print, it always doesn't stick properly, or it's to high? I would like to seek your help. Could you please also check if my Gcode code is correct?

This is only a part.

I can hear that the nozzle is touching the print bed, that should not happen.
If your printbed is not heated you should use double-sided adhesive tape

I'm indeed not using the heated printing bed. How can I find the correct printing center? When I print with the model pi 3mm , it always turns out crooked.

Yes, it becomes crooked because it isn’t properly centered. So before you start printing, you need to make sure that your nozzle is exactly in the middle of the print bed — it has to be accurate down to the millimeter. I measured my bed and marked a cross exactly at the center.

Before every print, I run G28 for homing and then move to X0 (or rather, to the center of the bed). Only after that do I start the print.

Also, as I mentioned, I use double-sided tape because I’m still not heating the print bed yet.

In the software, your X_Length also needs to be configured so that it matches your setup. For Joshua, it’s something like 115.5 or similar. It always depends on your specific setup.
