Basic Information: Printer Model: CR-10 V2 MCU / Printerboard: atmega2560 Raspberry Pi 4 Model B 4GB Fully updated Klipper and Mainsail After getting my first 3d printer, I ran a bunch of calibration prints and stress prints that all completed without problems. I then moved on to my first “real…

This is just a guess. I think your atmega2560 is too weak for your printing speed. Your klippy.log shows a high bandwidth from the beginning of your print Advanced Trouble-Shooting / Graphing Klipper . Good luck, hcet14

I did try adjusting the print speeds. The Print Speed setting is at 50mm/s and Travel Speed at 100mm/s, this also being the highest speed value out of all settings. Acceleration at 1000mm/s2. Would this still be considered too fast?

Sorry, I don’t have a CR-10. Do a search here or wait til someone answers. Good luck, hcet14

Hey Kevin, thanks for the link! I did already read through that, and these potential causes were also mentioned several other places I have asked or searched for this issue. I really went through my setup to ensure that it’s not something loose. My printer and Raspberry Pi are both using their own,…

Yes, debugging such can really really be frustrating. Unfortunately from remote there is not much more help we can offer. Good luck!
