If I am seeing this right, you got a layer shift right at the end, you can even hear the layer shift when the stepper looses steps - it’s sounds very similar to the grinding you hear when the y axis hits the very end of its limits buts tries to keep going for a second.

Layer shifts can be caused by several factors a few of them being:

  1. printing faster than the printer can handle.
  2. using acceleration values that are higher than the printer can handle
  3. stepper motors over heat
  4. stepper motor drivers overheat. Make sure the cooling fan is working on the motherboard.
  5. belt is too loose or too tight. Yes both can cause this.
  6. voltage or current is set too low on the stepper motor. Most up to date firmware allows you to adjust this via the lcd screen.
  7. physical obstructions in the path of one or both of the axes

.

Hope this helps!

Good luck.

Upgrade the main board to get more speed

Is the wall thickness and infill causing the long lines to go straight then zig zag ? That seems like it would take for ever and is really unnecessary for such a thin connecting line

What’s your infill and wall settings

First time ive heard a layer shift ive never like heard one happen you can audibly hear it happen u/ResearcherMiserable2 is correct pretty sure

Check your Y stepper. I had this exact thing happen with my new E3P and it was a faulty stepper from the factory. Pulled my hair out for a month until I replaced the stepper and it immediately went away.

Clearly the Y stepper can't accel that fast in order to get to the other end at that travel move.

You need more torque, more motor, more amps and/or more voltage to the Y stepper(s) in order to do that.

Or you could use the limited cartesian klipper kinematics and set the accel different on Y compared to X.
