Unable to Load and Print Files

[mookeyj79]

Hello! I am having an issue with the plugin where I cannot load and print files. I started with a fresh OctoPrint install, ran the setup script, soldered the serial connection onto the motherboard, and setup the USB.

Here's what's working:

• Serial connection is able to connect.
• Homing and moving the build plate
• Printer is able to see the emulated USB drive
• I am able to see the file details of the file I want to print

Here's what's not working:

• The load button
• The load & print button

Here's my setup:

• Anycubic Photon with the ChiTu L V2 board upgrade
• Raspberry Pi Zero W / Orange Pi Zero 2 (I tried both with the same results.)
• .CTB file sliced in both ChituBox & Lychee

Attached our my Octoprint logs. Thank you for your help, and please let me know if you need anymore information! octoprint-logs.zip

Make sure you are not slicing a CTBv4 file.

I have the same error on a phrozen sonic mighty 4k, non updated firmware, and I verified it was a ctbv3 file. I can also see the file on the printer, which printed fine. Opening and printing does not work on octoprint. This is what the log says: 2023-05-29 11:23:54,254 - octoprint - ERROR - Exception on /api/files/local/resin/raketovy motor V2 (2)_0.05mm_4h2m.ctb [POST] Traceback (most recent call last): File "/home/m/oprint/lib/python3.9/site-packages/octoprint_chituboard/sla_printer.py", line 126, in select_file sliced_model_file = file_format.read_dict(Path(path_on_disk),fileData["analysis"]) KeyError: 'analysis'

During handling of the above exception, another exception occurred:

So i finally got this to work by upgrading the motherboard from the ChiTu L V2 board to the ChiTu L V3 board. Using lychee, it does not matter if a select v2, v3, or v4 ctb, they all work with the plugin.

After formatting the pi, and reinstalling octoprint, the plugin is also working for me

Unfortunately i can't say is working for me, at the end i manage to mount the disk, the problem was the cable. I tried probably 9 of them. But when finaly the disk is initiated now the message from terminal is: Send: M23 _connector_light.ctb Recv: //############Error!cann't open file _connector_light.ctb! Recv: open failed, File :_connector_light.ctb Recv: ok N:36 Send: M4000 Recv: ok B:0/0 X:0.000 Y:0.000 Z:-10.000 F:0/256 D:0/0/1 ok Repl: ok T:0 /0 B:0 /0 X:0.000 Y:0.000 Z:-10.000 F:0/256 D:0/0/1 ok

I used chitubox and lychee, with v2,v3 and v4 and nothing works. Any ideas? I am very frustatred.

Thanks
