### Basic Information:
Printer Model: Ender 3
MCU / Printerboard: /dev/serial/by-id/usb-1a86\_USB\_Serial-if00-port0/ V4.2.2
Host / SBC Raspberry Pi Zero 2W
klippy.log
_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 had Klipper/ Mainsail/ Moonraker installed, then i bought another Ender 3. I tried to hook them up together, and everything crashed so I had to restart. After a few headaches and annoyances later, I decided to make each printer have an individual Pi for each.
Reconnected everything for Printer A, got Mainsail with Klipper up and running, went to do a test print and received “Unable to open file”. Changed Virtual sd card paths on both Mainsail cfg and Printer cfg to match, no luck.
I dont know what to do from here. If im missing information, let me know and ill get it as soon as i can find it.
Klippy Log:
[klippy (1).log](https://klipper.discourse.group/uploads/short-url/qSxwcrFHfPiw4JWDp5QDsfB06hd.log) (213.8 KB)
Let me know if the link doesnt work, ill paste the entire log if necessary.

Welcome Stego\_saurus,
use the search function here. I’m quite sure your problem was discussed before. E.g. [Unable to open file with new printer setup](https://klipper.discourse.group/t/unable-to-open-file-with-new-printer-setup/14238)
Good luck, hcet14
