What happened?

I got an error when trying to print a file from the home screen. "unable to open file" after checking on discord somebody suggested trying to print the file from the G-code screen. I was successfully able to print a file from the G-code screen.

What did you expect to happen instead?

I expected to be able to start printing a file from the home screen instead of having to switch screens to print a file

How to reproduce this bug?

Go to home screen and try to print a file from there. you should get an error that says unable to open file.
then go to the g-code screen and try to print from there

i tested it right now without any issue. can you pls give us a little bit more context? and also upload a klippy.log?

[Zchulski]

klippy (14).log

I have attached the klippy log. infurunately I cant give any more info other than from the home screen when I try to print something I get an error that says unable to open file. but if I try to print from the g-code screen it prints just fine

[meteyou]

can you post the filename from the gcode file?

[Zchulski]

moonraker (2).log
table tennis.gcode

i got the same error with every other file I tried to print from the home screen as well

I uploaded moonraker log too

I've had the same issue since upgrading to v2.13.0 and it persists in v2.13.1

I suspect it's something with the coding of the standby window in the dashboard.

Here are some examples from my moonraker log.

2024-12-06 19:46:59,940 [klippy_apis.py:start_print()] - Requesting Job Start, filename = I3 Parts/I3 Parts/V350_Motor Mount - Rod Mount v0.gcode
2024-12-06 19:46:59,959 [common.py:build_error()] - JSON-RPC Request Error - Requested Method: printer.print.start, Code: 400, Message: Unable to open file

Those two lines are from using the standby window in the dashboard
These are a successful start from the G-Code File menu

2024-12-06 19:51:39,124 [klippy_apis.py:start_print()] - Requesting Job Start, filename = I3 Parts/V350_Motor Mount - Rod Mount v0.gcode
2024-12-06 19:51:39,214 [job_state.py:_status_update()] - Job Started: I3 Parts/V350_Motor Mount - Rod Mount v0.gcode

Looks like the standby window in the dashboard is adding an extra folder

I3 Parts/I3 Parts/V350_Motor Mount - Rod Mount v0.gcode <--vs--> I3 Parts/V350_Motor Mount - Rod Mount v0.gcode

Looking at OPs moonraker log I see the same issue.

2024-12-08 11:03:47,426 [klippy_apis.py:start_print()] - Requesting Job Start, filename = 737 Overhead/737 Overhead/table tennis.gcode
2024-12-08 11:03:47,432 [common.py:build_error()] - JSON-RPC Request Error - Requested Method: printer.print.start, Code: 400, Message: Unable to open file

vs

2024-12-08 11:08:02,212 [klippy_apis.py:start_print()] - Requesting Job Start, filename = 737 Overhead/table tennis.gcode
2024-12-08 11:08:02,336 [job_state.py:_status_update()] - Job Started: 737 Overhead/table tennis.gcode

It's doubling the first sub directory "737 Overhead/737 Overhead/"

I suspect that whatever code is in the standby window it's probably got a variable in twice accidentally.

I'm glad I came across this! I thought it was something with my switch to a new pi and I've been feeling like a crazy person.
Edit: For those who need a workaround, I have two: When uploading a new file you it will still upload and print or if you use something like mobileraker it will print from there.

@Lexanger all files from the root directory will also work, or just print it from the gcode file page. there is also no issue with subdirectories.
