Like the top link
After finishing printing, there is a problem that the z-axis comes down and finishes.

Eventually, the output of 20 hours was destroyed.

Others also asked if there was a problem with the z-axis coming down at the end. There were many people who came down.

However, even if I searched the g-code, I could not find any problems coming down.

I think M84 is the problem. Has anyone solved it?

This is a serious problem.

Hi, can you post the complete G-code file here? And which software you used to generate the G-code?

Snapmaker Luban was used.
However, it was the same when using the previous version of the Snapmaker tool.

Hey, here is a thread to read for your problem. Unfortunately I have and want no facebook.

Thank you for your interest.

I uploaded the video to youtube

However, This is a different issue than the link issue.

For reference, this is the back of my gcode.

The results I checked.

In the’M84’, the z-axis seems to go down.

What is curious is that the y-axis goes back to the end and then back to the front.
While pushing out the prints, it sometimes breaks.

First, I deleted’M84’, preventing it from coming down.
Some of the solutions are in one state, but I don’t think this is the right answer.

It’s the same problem.
