the chithuboard plugin didn't work for Elegoo Satrun2, cannot print from ctb files in the SD card

[biolifei]

My Elegoo Saturn2 printer cannot start to print any uploaded files on the 64 GB SD card when it is operational after connected to Octoprint server. I installed OctoPi version: 0.18.0 with OctoPrint version: 1.8.6 by using the Raspberry Pi 4B connected through /dev/ttyS0 baudrate: 115200. The octopi is installed with octoprint plugins chituboard. The priner is connected by the jumper wires from the Raspberry Pi’s GPIO pins to the Elegoo Saturn2 motherboard. The TX pin is connected to the motherboard’s RX pin, GND to GND, Rx to Tx. The Pi USB connector is connected to the “USB Disk” USB port on the printer’s motherboard with the USB Power Blocker to strip 5V from a USB cable.

The plugin doesn't yet support the CTBv4 files, I'll fix it once I have some time.

That explains it. I just finished setting everything up and was able to get the print bed to home and move, but the files were not visible.

Any updates on this? I've got a Saturn2 and would desperately love to have this working. If there's anything I can do to assist, I'm more than happy to test/help.

I'm having an odd problem that sounds related.

Files that I slice with chitubox aren't accepted by the printer. I assume that's because I didn't update the firmware. However, files I slice in lychee work just fine.

Then I added the pi02w, and now it's telling "invalid file type" when I try to upload.

I wonder, if I slice it in chitu, would the file transfer ? And if it does, would the printer accept it without the firmware update which would preclude me from using the CTBv3 files anyway

The error says that it only wants gcode, but it doesn't say that til it's almost 100% uploaded. I have to drag n drop. It doesn't like file transfer thru octoprint file select
