I got one of these and it has a problem.

I got one of these and it has a problem. so the first layer is a cross. it made the outline, but when it started filling it, the whole thing was shifted 30 mm up. I think the y axis belt is slipping. What can I do?

It could be a number of issues, such as the stepper motor not moving when it needs to. What type of printer is it?

It’s a creality cr7

I don’t have much money
I think the belt might be slipping it’s a kit and it doesn’t have a good way of tightening it.

That link didn’t seem to go anywhere. If you can do a picture of the printer and the failed post, we might could help more. I’m assuming it’s the motor, but it could be caused originally by the extruder head hitting the surface, for example.

sorry
