[Problem with printing quality after change to 3dsolet sapphire ruby nozzle.]

I don't think this has much to do with the nozzle.

 

This is a common problem with all 3d printers and can be fixed.  

 

The basic issue is that it slows down too much on the corners versus the rest of the print and so you get overextrusion on the corners.

 

On the UM3 for example a quick fix is to disable acceleration control.  That way it spends MUCH less time on the corners.  Other fixes include increase jerk, increase acceleration, decrease print speed.  Also for a part this small infill may be partly to blame - cura typically does infill at a higher speed than outer walls so consider making all the speeds the same.  But this is likely not the issue.

 

Another possibility is that your cad part has too many line segments on the corners.  Cura slows down a lot if there are many line segments in a small space (say < 1mm).  This is obvious if you watch it print - it basically stops on the corners.

 

So...  what kind of printer is this?  Does your printer use a bowden tube?  Does it use Marlin firmware?

Thank you for your feedback. Good to know that it is not the nozzle  ? I just bought sapphire kit for my UM3

Hello ?

I have problems with the corners on my print and furthermore there is problems with the print quality.

 

 

In this picture, you can see how the corners are not sharp. 

 

 

I hope some other people have some experience with ruby sapphire from 3dsolex.

No, there's 2 ends to the cable. It goes into the printhead PCB board, and into the main electronics board. But since the main electronics board under the printer is stationary, if something needs to be reseated/came loose, odds are it's going to be the printhead PCB, since the printhead is constantly moving. If the cable did need to be replaced, you do have to access both ends.

Thank you I found information about it ?

I'm glad your printer is fixed. Most of the time an ER18 can be resolved by reseating the cable; very occasionally I've persistent ER18s that require a replacement cable.

So the only place you can be reseating the cable is on the motherboard?
