Did anyone have this layer separation problem before? I have bought this printer for 2 years and this is the first time ever have this problem. I look up online and did not find any similar issue like this. Most other layer separation problem is caused by cooling and you can see warp on separated layer level on those example picture. But here is no warp on my separated layer. It just looks like the layer did not stick to the previous for couple times and then it stick back again.
Pleas check the picture for more detail.

Re: Layer Separation
Do you only have this issue with one type of filament or all types of filament?

I am only printing PLA right now. I am not sure if this will happen on other materials.

Re: Layer Separation
Looks like the extrusion is not continuously good. What was the temperature you set for this filament? Did you see nozzle temperature changes a lot during printing?

I agree - looks like under-extrusion/jam/slipping...

This looks like the filament has gotten "wet" and needs to be dried out. Water has been absorbed into the filament at a molecular level and is being vaporized as the filament is extruded through the nozzle. This leaves gaps that can cause the poor layer adhesion you're seeing.

I don't have a temperature monitor. Is there a way to monitor the temperature while its printing??

Do you mean the filament is not good already before the print?

Please check whether the nozzle temperature values on touchscreen change or not during printing.
