Skipped steps. Check for mechanical problems, make sure the carriage moves freely along the axis, and try a little more current to the motor.

2 Amp power supply? Is that a typo? If not you are way under powered, which would cause your issue.

Have you tuned your steppers? Second thing I check after friction.

Hi Papa,

Pulleys could be loose, mark them to see if they are slipping. I've seen this happen and the result is similar to your prints... sort of random shifting usually in one direction.

Looks like that is fishing line instead of a belt right, so the belts are probably not too tight.

Otherwise, like others mentioned, stepper motors count need the current adjusted... either too much or too little. Turn the current down until it doesn't move, then slowly bring it back up until they are strong.

Here's video of me tuning one of mine:

Let us know how it goes.
