LIMIT SWITCH HASN'T PROBLEM BUT ER17...WHY?

[dminsb 0]

Unexpectedly today, While I changed the material,

My Ultimaker3 show me the error massage "ER17 - The X or Y axis is stuch or the limit switch is broken", at the same time with the Head trying to move more back & left

(with a sound 'ddadadadadadadadadaa~~~~~~!@!@!@'),

Although it has already arrived at home position. 

 

(troubleshooting : ER17)

https://ultimaker.com/en/resources/23151-the-x-or-y-axis-is-stuck-or-the-limit-switch-is-broken

 

But the limit switch has working while "System > Maintenance > Print Head > Home.

 

So, I think the switch is not broken physically. it works...

 

So why?

 

Is there anyone has the problem same with my case?

 

How did you solve that issue??
