Multible klipper(4) instances on btt-pi

Basic Information:

Printer Model: ender 3 ish
MCU / Printerboard: creality 4.2.7

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 cannot open a file in klipper I use the browser window to run this and I load file like I normally do for the creality pad but when I load the file it shows up in the btt-pi folder for this instance… I am running 4 instances I can move all the heads and control temps and get a mesh … I just cannot print it just says it cannot open file I need to get this figured out I have a lot of printers to get running and I love klipper

thank you for any and all help
I used kiauh to install the 4 instances I have read and changed all the printer .cfg and mainsail.cfg and moonraker.conf

mcu 'mcu': Unable to open serial port: [Errno 11] Could not exclusively lock port /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0: [Errno 11] Resource temporarily unavailable

Looks like your printer boards all or some of them register with the same connection serial. You could try /dev/serial/by-path or make yourself familiar with UDEV to construct unique endpoints.
