Hi Sineos, thank you for the reply. I will go look for the template? However, per WCSP … the file is exactly where it says its supposed to be? ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/7/7be3c0d6ec1369546636421342ae0291ff3dfe1a.png) ---

This seems strange. Please attach the `klippy.log` and `printer.cfg` ---

Here are the two files.

As for the klippy.log, the printer.cfg is found. There is a different issue: ```auto mcu 'mcu': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb_Klipper_stm32f446xx_0B0030001350535556323420-if00: [Errno 2] No such file or directory: '/dev/serial/by-id/usb_Klipper_stm32f446xx_0B0030001350535556323420-if00' ``` Is the printer connected properly? Is the printer flashed with the proper firmware? ---

Thank you for the reply. 1. Is the printer connected properly? I think so. I am using the octopus 5V PI shield that was provided to power the PI4. I also have the USB connecting from the Octopus USB A to the PI USB C. I have confirmed that only the 5V is powering the PI. I assume the USB is only for Comms between Pi ↔ Octopus but i am not sure how to verify that? 2. Is the printer flashed? I think so but how do I check … I followed the steps in the Klipper guide. I copied the Firmware.bin file from the PI Sd Card to the Octopus SD Card using WSP. When I run “ls /dev/serial/by-id/” it returns the serial number that I have pasted into my printer.cfg file? Is there something else I can do ? Thanks in advance for your help Is there a paid support service anywhere to which a user can subscribe? > **(attachments)** > > ![1000005868.jpg](https://global.discourse-cdn.com/free1/uploads/klipper/original/2X/8/81bef4f94bb3f258feb643de59f805973057e267.jpeg) ---

Sorry, I mis-quoted the USB set up. I have the USB cable from Octopus USB-C to PI USB-A. ---

I found it. I had a dash where I needed and Under\_score in the device name. Thanks again. ---
