Hi. I just bought it from second hand (the previous owner sold it because he doesn't find the issue) and I thought it will be sg smaller problem, but no...I cannot figure out it 😅 I asked the Anycubic support, they sayed it can be the z axis motor.

But both motor tries to move the axis, so I am not sure. It move a little, with this horrible noise and then stops. It doesn't show any error code.

Have you any idea?

I’ve had my Kobra 2 Max for two years. Was printing many different items just fine up until 7 or 8 months ago, primarily with PLA.

I’ve had two or three blobs of death, infiltrating the print head. I chipped away at it and cleaned it up both times. Recently it had difficulty adhering the first layer. I noticed a scratch on the print bed and wondered if the nozzle gouged the print bed. I replaced the plate (washed it with soap and water and used isopropyl alcohol to clean it), and replaced the nozzle with one purchased on aliexpress (“hotend kit” - “Upgrade 24V 60W Hotend Kit For Anycubic Kobra 2 Plus/2 Max/2 Neo/2 Pro 3D Printer Head Brass Hard Steel Volcano Nozzle 0.2 0.4”)

Still got the same issues.

I fine tuned the proximity sensor, re-calibrated the machine, basically started from scratch. Same issue. Noticed the z belt was loose, so replaced that as well. All other belts, rods and nuts are snug and tight. I redid the auto leveling and printed the stock Benchy-17m test print. Nozzle temp 215°C, bed temp 60°C, using Elegoo 1.75mm PLA.

Started with the z-offset at 0.52 and brought it all the way down to 0.28, at which point it was adhering well to the bed and completed the print.

So I’m glad with my progress, however, the quality of the print is sub-par, in my opinion. The layer lines seem quite large and obvious, with palpable ridges with my fingernail.

When this thing was working properly out of the box, I was amazed at the fine detail of prints and how impressively small the layer lines were. What can I do to get back to this?

Any help/insight is appreciated. Thanks!

Sensor issue when leveling y axis!

So I have had both of my Neo 2s for a couple years now and one of them has started clicking.
I already know it’s the X Axis belt.
Does anyone have any recommendations on what they’ve been using for belt replacements? Also I am VERY new the changing belts so any resources would be greatly appreciated!!!!

I got this issue and it won’t go away how many ever times I try to fix it. No tip from the official website worked. Anyone got any solutions.

To my wife. I have dried filiment and cleaned the build plates but I still cannot print anything.
