Leaning prints, initial layer shifted

Recommended Posts

Posted · Leaning prints, initial layer shifted

New to 3D printing, have new printer, leveled bed, running test prints to tune settings for quality...

 

Attached pics tell the story

Already checked all belts/pulleys.

Any suggestions?

 

Thanks!

Hi there, thanks for getting in touch.

 

It's really difficult to diagnose remotely. From your bottom image it looks like your print is warping on the plate, so try using adhesion in Cura. A brim will give it some anchorage to the bed and can be removed when finished.

thanks, the part was printed using a bed layer, the top two pics show the beginning of that initial layer.

I agree - for the bottom photo you need better adhesion - level your printer so it squishes the bottom layer more:

For the upper photos it looks like one of your axes is slipping.  Do you know which one?  X axis?

 

This can have MANY causes.  The most common is a loose screw on a pulley - you have to tighten the hell out of those set screws - enough so the tool twists (typically - I don't know your specific printer).

 

Also if you built this printer yourself or messed with the settings, you may have "jerk" or "acceleration" set too high on the printer for the axis that is slipping.  Typically if the entire bed moves - that axis has to accelerate more slowly.

 

Also the slipping axis might have much more friction and the steppers just can't accelerate that axis normally.  Or your stepper drivers may be overheating and shutting off (they typically shut off for a portion of a second).

By the way - a third issue - in the bottom most photo you posted - those 2 vertical lines look vertical so no axis slipping there - but the curve is wrong - concave instead of convex.  That's typicall when the bed is too hot.  As you get farther from the bed you get less heat.  With high heat the liquid PLA is pulling inward like a liquid rubber band as it prints that end of the part.  But as you get to cooler air a few more mm off the bed it recovers.

 

60C is a good printing temp - if you have an IR temp sensor you can check the bed temp with that.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
