[UM3 stoped mid in the print, then ER16]

er16 came in 1/3--1/2 of the print. (and it wasn't any big -- just two tubes d32x2x18)

 

If you are right about 24V -- where should I measure it? I have mutlimeter somewhere around. Before I start to break things apart it would be nice to check it.

[UM3 stoped mid in the print, then ER16]

After some 20--30 minutes the printer just stopped. The nozzle was not moving. Display showed only info about remaining time. 

I tried to pause and restart the job -- nothing happened.

After cancelling, the printer didn't drowe any axis. eventually it displayed error ER16, which is for Z-axis limiting.

I drowe the axis manually and could hear the "click" nicely and clear.

 

Just to be sure I cleaned and lubricated z-axis. 2 days later the same error.

 

Any ideas how to search for the reason of this error?

 

best regards
