E180 motor problems

Hello!

After some successful prints I turned on my E180 today and wanted to check the leveling. But on entering the screen nothing happened, even when tapping the positions.
Then I tried the manual control. X and Y did something, but ended up in an end position with still full engine power (you could hear the hum). When you diabled the engines you could see them "relax" from the end position.
And Z did nothing at all still. The position showed 132mm , although it was all the way up.

Is something wrong with the positioning sensors? Anything I can reset there? Or try out?

Thanks

Could you upload the video about the issue?
What info have I get is:
The voltage of A4988(blue type) seems not correct(0.7-1.0V)

You can use a multimeter for a test
How to increase it up to 0.7-1.0V?
You can adjust it by the top adjustable resistor

Hi William,

I made a video of my issue. But I can not post attachments to this forum.
So I will send you a PM.
