The USB-OTG port on the Raspberry pi 4B is also the USB host port.Some people online do this, but I didn’t want to do any permanent changes to my Pi. Cut the connection between the 5V line and the USB port on the Pi.

This tutorial is a good reference on how to do this.

Put some tape on the 5V line of your USB cable.

The printer can only supply around 500 mA via the 5V line so its best to power you pi with an external power source. The printer mainboards use the USB port to read USB FAT storage devices not for serial control. Our goal here is to use the Pi as a USB flash drive.

Supported printers: SLA printers with chitu3d mainboard, Anycubic mainboardsįollow hardware setup instructions in source repo.

Doesn’t work properly in a docker container, designed to work with a fresh Octopi install.

Raspberry Pi Zero W (not recommended underpowered), Zero 2 W, 3A+ or 4B only supports raspberry pi’s with USB-OTG ports.

I’m not planning on incorporating the non FOSS chitubox SDK into an AGPLv3 licensed plugin.

Plugin might not work if you’ve updated your Elegoo Mars printer to the newest firmware due to issues with Chitu3d encrypting their files so users are forced to use Chitubox 1.9.0.

File analysis CLI command works octoprint plugins chituboard:sla_analysis NAME.

upload files to folder ~/.octoprint/uploads/resin.

Compatibility layer for SLA printers with Chituboards like the Photon and Mars seriesĪdded basic support chituboard based printers(Elegoo Mars, Anycubic Photon, Phrozen, etc.) to octoprint.
