Some layers have an offset. Why?

Recommended Posts

Posted · Some layers have an offset. Why?

I used the default definitions of Cura software, and it resulted on this problem.

Looks like a hardware issue. Backlash in gears or slack in belts. The hole likely causes the printhead to travel in the other direction, so the backlash/slack bias is on the other side.

Hey, I just got the same problem. I checked for play on all of the belts and retightened all the pulleys but still, the problem occurs when printing holes...

 

It would be nice if someone could help me with this problem

I have the same problem too, even if the hole is hidden inside the model.

Could you save a project with the same settings and upload it? I mean not only the gcode, the whole project (xxx.curaproject.3mf)

What printer are you using?

I have the same problem and checking belts, axles particular, etc. doesn't really help. It is not isolated to holes only, it happens everytime when there is "something" in the model and the direction of the nozzle changes (clockwise, counter clockwise).

 

I opened a thread here with pictures:

 

Printing slower helps, but it gets only "better".

@Smants and @Julian2801

Are there any news, solutions for this problem or have you found a workaround for it?

 

In the meantime I tried a lot, but still haven't found a solution. Or maybe someone else can give an advise how to solve it?

@Adrunodro

I don't know anymore what was the seetings I used, to put my project here.

My printer is Ultimaker Original

 

@Smithy

To minimize the issue, I had to print with reduce print speed.

Is this the same problem?

It isn't a huge problem since that is referred to an upper empty part, but yes, it is the same.

Depending on the model (holes, etc.) it is more less visible in every model and on every printer. I made some tests with my 2 printers with different models and also a friend of mine have similar issues on his  Anet A8. Most of these issues are only visible and a few of them you can feel with the finger.

 

In the meantime, I think it is "normal" as I have found such issues also in most pictures of printed parts on various pages in the internet. 

 

It helps to print slower, very slow and it depends also on the material. Darker, brighter, glossy or not, these all makes huge differences how much visible it is.

Well yeah the problem is to me it isn't just visible, the parts will split cut in those layers.

Thanks @redslifer.

I had improvements by increasing the cooling time

Oh really? Then it should be useful trying with a double 5015 cooler to see what the actual result would be. Even trying with a bigger and better hotend fan, as my actual one is a standard 30mm V6 fan and I could try with a 40mm fan. My 5015s are on the way.
