Basic Information: Printer Model: Creality Ender3 V2 MCU / Printerboard: Stock - 4.2.2 klippy (3).log (40.6 KB) Recently discovered Klipper and as I have multiple printers thought I would have ago at setting up. Installed on Laptop (linux) and able to connect via ssh on a separate PC. Followed…

[image] Sineos: sudo systemctl list-unit-files brl* Looks like you may have found the issue. The results where :- UNIT FILE STATE VENDOR PRESET brltty-udev.service static - brltty.service disabled enabled Disabled is showing in red Enabled showing in green. Just thou…

Do: sudo systemctl mask brltty-udev.service sudo systemctl stop brltty-udev.service sudo systemctl mask brltty.service sudo systemctl stop brltty.service Then reboot and try again. If it does not work, please post a new dmesg output and the corresponding klippy.log

[image] Replic8Gaming: sudo dmesg Thanks again. Still no change . I’ve attached both files as requested. Not sure if this of any use but the following lines from the dmesg file are shown in red [ 0.130000] x86/cpu: VMX (outside TXT) disabled by BIOS [ 0.107185] DMAR: [Firmware Bug]: N…

This is Ubuntu, right? This is running a dedicated Linux and not a virtual machine? x86/cpu: VMX (outside TXT) disabled by BIOS → Just an info that certain virtualization extensions are disabled in the BIOS DMAR: [Firmware Bug]: No firmware reserved region can cover this RMRR → also some virtualiza…

Strange, it no longer shows an intervention of BRLTTY but it immediately disconnects. Please show the output of ls -al /usr/lib/udev/rules.d/ If there is anything like brltty-device.rules then do: sudo mv /usr/lib/udev/rules.d/brltty-device.rules /usr/lib/udev/rules.d/brltty-device.rules.bak Th…

the only line that shows BRLTTY is -rw-r–r-- 1 root root 17401 Jun 28 2022 85-brltty.rules

Then do sudo mv /usr/lib/udev/rules.d/85-brltty.rules /usr/lib/udev/rules.d/85-brltty.rules.bak and reboot

still no change, not sure what causing this as the first time I tried I actually for the address then a firmware was installed and its never got to that stage since. I take it having secure boot disabled wouldn’t affect it at all

From the Linux side, I would think we are clear now. Start again with reflashing the board. Use klipper/printer-creality-ender3-v2-2020.cfg at master · Klipper3d/klipper · GitHub and especially mind the information on top of the file. Follow Installation - Klipper documentation for the general pro…
