### Basic Information: Printer Model: Ender 3 pro MCU / Printerboard: SKR Pico with Pi Zero W `klippy.log` _Fill out above information and in all cases attach your_ `klippy.log` _file. Pasting your_ `printer.cfg` _is **not** needed_ ### Describe your issue: So… I’ve had a number of issues trying to get my ender 3 running after a thermister issue… which led me down a very long and expensive road to get to this point! 😃 after asking the _ahem_ helpful people on reddit i thought it made sense to come here instead. Basic issue… I’ve installed mainsail on my pi zero w, can connect to the web interface fine. I am connecting the pi zero to the SKR pico via UART… I can’t clarify which port it’s using either ttyAMA0 or ttyS0… also for some reason the klippy.log shows it cant find the printer.cfg file in the directory it is in? [moonraker.log](https://klipper.discourse.group/uploads/short-url/f9DHYvva8Tkd9TgqpsxSwirna4.log) (255.8 KB) [klippy.log](https://klipper.discourse.group/uploads/short-url/idooF4TTHuZuFk4xD9P3abtGOJs.log) (410.9 KB) I added the moonraker.log too… hope it doesnt have anything it shouldnt in it… anyway… I’ve also tried kiauh which seemed to get me to the same point. Any ideas would be awesome… been at it for 2 days now…just on the setup side of things… I used NERO 3D’s video for inital set up so i know it should work… Thanks in advance! (hope its in the right place!) ---

Post the content of your `config.txt` and/or `usercfg.txt` and/or `syscfg.txt` and/or `cmdline.txt` file. The files can be found in the `/boot` or `/boot/firmware`. Which of them exists and where depends on the Linux flavor you are using. ---

[cmdline.txt](https://klipper.discourse.group/uploads/short-url/di5Nvyafamv2R2ULW1TyxiNL6M7.txt) (80 Bytes) [config.txt](https://klipper.discourse.group/uploads/short-url/9n0ayYT8SNX3Bnsh9dcIUCqU3jN.txt) (3.2 KB) I thought it may be easier attaching them, I’m using mainsail os… i actually tried it with a pi 3b and it still didnt find it these were the only 2 files i had out of what you mentioned ---

I may just start again from scratch as I’m sure i’ll have messed it up somewhere ---

Your settings are looking good. - What is the output of `ls -l /dev/serial*` - You are using GPIO 14 (pin 8 / TX) and GPIO 15 (pin 10 / RX) of the RPi? - You are correctly connecting RX / Pi to TX / MCU and vice versa? ---
