Layer Shift

[tc61]

I am printing from the right Extruder and have gotten 3 failed prints in a row where the layer shifts significantly about 2 hours into the print. I have used the machine maybe 4 times , any guesses as to what this could be?

There are about 17 different things that can cause layer shifts.
A few that come to mind are
Condition of the gantry rods (lubrication, cleanliness).
Speed, acceleration, jerk settings exceeding machine capabilities (either travel speed or print speed).
Material collects on nozzle - drops blob on part surface causing a nozzle strike.
Part warping/lifting causing nozzle strike.
In very rare cases that can be a slicer bug that causes an error in the GCODE.
Exceeding firmware travel limits.

Are you using any Z-lift? That can help prevent nozzle strikes if warping is a contributing factor.

Sharing some information about your printer, the part, material, process settings .... would help us understand what you're doing.

Thanks for the reply.

I don't think its a Lube or cleanliness as the unit is brand new.

I am using the stock PLA setting with the included PLA

Nozzle looks clean and new.

I sliced the model in Ideamaker , it had no errors.

If the default profile does not include Z lift then I do not think so.

The first layer was flat and about 40 layers in is when it happened.

I am printing a Benchy now just to see if the problem repeats its self on a different model.

I will keep you posted.

You say the first layer was flat. Not sure what you mean by that.
Is the bottom surface of the failed print perfectly flat?

[tc61]

Yes, it was a perfect print until the layer shift. No lifting

Would you like to share some images of the failed parts if possible?
Would you like to print a small calibration cube to see if the issue is repeatable or it only happens on large models?

Same here E2 is brand new about a week old and 10 hours into a print layer shifts.
I have experienced this on all printers I have owned. 90% of the time it was the machine stuttering due to being too hot. Other printers I would raise them up to get better air flow. So my question is what’s the best solution it reducing heat on the logic board.

Would you be able to attach a few images of the failed prints that you have enocountered?

Would you be able to attach the Gcode file for this model? And possibly the .stl file?
