Strange noise in XY motion

[fergazz 60]

Hi all!

After a strange noise during printing the Forbidden Watchtower by Kjai I paused, resume and paused again and quit this print. Looks like it also cause a layer shift:

What's going on here? By the way I'm using UM2(+) printer, Simplify3D v4 and thinkerMarlin 17.10.1 as firmware

 

1: Bearing problem?

2: Lack of lubrication on XY the axles? It's tought to move with printer shutted down.

3: Slicer problem? In preview looks fine. Firmware problem? 

4: Belt? Everything seems in place.

5: None of the above ?

After the last pause I comand, in control panel of Simplify3D, to home all, but it collapse on the left corner and I hit Emergency Stop.

well, I lubrificated all axes and tomorow I will give it a test. 

 

If weird stuffs keep happening I will install an earlier version of tinkerGnome.:

Make sure to power-cycle the printer. There was an inexplicable case where the print head made a sideways move during a print. Maybe this is related.

 

You mentioned that it is tough to move the head by hand. Maybe the belts are too tight. You should definitely not move the entire printer around if you move the print head.

@Nicolinux

just to give you a feedback. After a power-cycle and some oil the printer is running without issues, I printed 3 stuffs after that and everything is ok! It was weird!

 

Thank you ?
