Unable to open serial port

[Ltek]

Followed the instructions 100% but no matter what I try it doesn't connect (also tried multiple cables also; it flashed fine with the first cable). Klippy.log errors below.

can you confirm it does show up in a ls -l /dev/serial/by-id/

[Ltek]

It was odd but after multiple reboots (Pi & printer) it started connecting fine.

just as a follow-up from this thread I was also having issues, then I found a comment from Kris S. in the amazon product page that finally made it work here

The Fysetc instructions on Github are not complete and unless you are a pro you may have issues getting it set up.

With the help from klipper discord these instructions helped me get it set up.

MAKE SURE YOUR KLIPPER IS UP-TO-DATE

Via SSH to your PI with Klipper installed
1. Change directory to Klipper
2. make menuconfig
3. set menu per image on Fysetc PIS Github
3.1 Do not enable extra low-level configuration options
3.2 Set Micro-controller Architecutre to Raspberry PI RP2040
3.3 Set communication interface to USB
4. Exit and save menu config.
5. sudo service klipper stop
6. make flash
7. sudo service klipper start
Now the firmware 'klipper.uf2' should be created and located on your pi in the klipper/out directory

FTP into your PI
1. Navigate to the Klipper/Out directory
2. Download the 'klipper'uf2' file onto your pc desktop.
3. Exit and quit FTP

Now flash the firmware 'klipper.uf2' onto the Fysetc PIS
1. Press and hold the button on the Fysetc PIS
2. Connect the PIS with USB C to your PC
3. Release the button on the PIS
4. A folder named RPI-RP2 will pop up
5. Copy/Move the 'klipper.uf2' file from your desktop into the RPI-RP2 folder
6. Wait - the folder should close automatically
7. Unplug the PIS from your PC

Now set up PIS on your PI via USB
1. Press and Hold the button on the PIS
2. Connect PIS to your Raspberry PI

Now set up the firmware
1. Via SSH issue - lsusb
2. locate the device ID for the RP2040 -- i.e. Bus 001 Device 008: ID 2e8a:0003 Raspberry Pi RP2 Boot
3. Copy the ID i.e. '2e8a: 0003'
4. CD to your Klipper directory
5. issue command- make flash FLASH_DEVICE=2e8a:0003 << CHANGE TO YOUR DEVICE ID
6. You should see that the UF2 has been flashed

Now lets find the serial address for the Fysetc PIS RP2040 connected to your PI
1. issue command - ls /dev/serial/by-id/*
2. copy the address denoted with rp2040 -- ie. /dev/serial/by-id/usb-Klipper_rp2040_E66160F4235E4038-if00

Now lets create the PIS.cfg in klipper
1. Machine >> Create File >> name it PIS.cfg OR download it from Fysetc git up and upload the file
2. Copy contents from the Fysetc PIS file into your kipper PIS.cfg
3. Edit the "serial" line to have your path you copied from the prior steps for obtaining the serial address
4. Save/close/restart Klipper on your PI
5. Edit your printer.cfg to add a line that includes the PIS.cfg -- [include PIS.cfg]
6. Save/close/restart Klipper on your PI

Now make sure you have completed these steps denoted in klipper3d / Measuring_Resonances.html
1. sudo apt update
2. sudo apt install python3-numpy python3-matplotlib libatlas-base-dev
~/klippy-env/bin/pip install -v numpy

Now your Fysetc PIS should be ready to use and your PI/Klipper setup ready for the Resonance Compensation Input Shaping testing.

BTW, I have learned you can now flash directly from kiauh. no need to press the boot button. worked from kiauh wohoo

I don't understand the double flashing here? why are we flashing from the PC only to reset the device and flash again from the PI?

This was the only way I could get the stupid PIS to work.

I have followed every guide out there and still with no luck. I am running moon raker and fluidd from my raspberry pi. Would this method you're talking about work?

[DaVinci-10]

You can DM me either here or on Klipper discord or discourse boards with same name. I can help walk you through it.

@DaVinci-10 Not sure how to DM here, but I sent you a request on Discord

Thank you @gabriellferreira, the 'make flash' was the missing step, copying the file doesn't seem to flash the device automatically as other guides have indicated.

In case anyone struggles, you need to be in the ~/klipper/ folder for that bit to work.
