Layer shifting in Y-Axis, more noticeable with PETG
Hello all. I'm fairly new to 3D printing and could use some guidance. I assembled a kit and made more than a dozen prints so far. I noticed that there were more significant layer shifting issues with PETG. I believe that I have Y-axis layer shifting issues and wanted to get some input from others.
- I checked and all of the tensions are between 240 and 300. Y Axis tension is 244.
- I cannot see anything blocking the path and when pushed manually, it seems to be smooth all around.
- I recalibrated and it seemed to make layer shifting worse.
I printed the same 3D model using the following filaments:
- Printed using Hatchbox PLA Red (Printed the best IMO)
- Recalibrated 1st layer and used Overture PETG Black
- After full calibration, used Overture PETG White
I performed full calibration between black and white Overture PETG filaments and things seemed to get worse, LOL. I am stuck and don't know what I should be trying next. Any help would be appreciated! I am assuming that it's isolated to Y-Axis problem, because the layers are shifting to the left (layers sticking out in the last picture).

check the small screw on the gear conecting to motor

and only do calabration on 1 color as diffrent colors can vary slightly take a picture of the axis motor and rods and the underneeth of the bed thanks

Thank you for the reply @hello! You are right.
I actually tightened the set screws before seeing your reply and have been printing without noticeable layer shifts! I thought I had tightened all the screws when building the kit, but apparently not.
Since you are a SME… I have another issue that I’m scratching my head on. Do you think it has to do with the print/fan direction? There was only one noticeable issue on this run.

please take a photo of your extruder from all angles so i can see if its built right thanks

It was printed using Overture PETG at default settings (“Generic PETG”). I kicked off another print, so I will post pics of the extruder tomorrow. Thanks again!

Here are the pics. It’s printing fairly well right now though. Not too many issues as far as I can tell, but you might see something. Please let me know!

I would tighten the extruder screw slightly
