General Discussion

Basic Information:

Printer Model: Ender 3 V3 SE
MCU / Printerboard: stock
Host / SBC
klippy (7).log (538.0 KB)

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

I’ve set up and installed Klipper by following the guide at Ultimate Guide for Klipper Installation on Ender 3 V3 SE - Artamis, adjusting the steps to install on Ubuntu with WSL (Windows Subsystem for Linux), as I don’t have a raspbi I could use.
After flashing my Ender 3 V3 SE and accessing the web interface of both fluidd and mainsail failed to connect to the printer it seems:

mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/<your-mcu-id>: [Errno 2] No such file or directory: '/dev/serial/by-id/<your-mcu-id>'

from the host, both ttyUSB0 and /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0exists and in my config file I have it correspondingly

[mcu]
#serial = /dev/serial/by-id/<usb-1a86_USB_Serial-if00-port0>
serial: /dev/ttyUSB0

I have tried them both, but the problem still persisted.

Thanks in advance for the help

Hello @printamar !

This seems to be a kind of VM.

Well I used this bin and cfg and it worked! but when it conected the bed shot up to 100c and when I tried to home it said that: !! Endstop x still triggered after retract. what does this mean and how to fix it?

So now, what do you have

  • Connection issues

or

  • Configuration issues?

idk. thats the config
printer.cfg (5.3 KB)

Form that config:

Creality Ender 3 Pro

You printer

That are different printers and it it is unlikely that they have the same board. So your issues with endstop and bed heater.
