BTT Octopus Pro v1.1 with BTT Pi v1.2.1, Getting 502 Bad Gateway error
Greetings All,
I have a SecKit CoreXY printer that I want to upgrade to use the RatRig ecosystem on a BTT Octopus Pro V1.1 (H723) and a BTT Pi V1.2.1. I'm using 32 GB SanDisk Ultra MicroSD HC1 in both boards. Everything is brand new and never used until now. (Also bought their accelerometer board.)
A friend of mine is running his Voron on the same boards and software, though I'm not sure what version of RatOS he began with.
I downloaded the latest pre-release RatOS-v2.1.0-RC2 from the GitHub page and installed it on the BTT Pi. Followed the instruction and updated both the ratos and ratos-configurator. I then refreshed the update manager panel and ran Update All Components.
I could still connect to the board after that. However, when I attempted to go the configure page I got the 502 Bad Gateway error. Got lost after that and tried things like installing the current Latest version RatOS-v2.0.2 which didn't go well. I'm now going to go back and reinstall the latest pre-release again.
Questions:
* Will the BTT boards I purchased work with the newest release of ratos ?
* How can I resolve the 502 Bad Gateway error if it happens again ?
Thanks for any insights you can provide !

Update: 04/02/2025
Redid everything with the latest pre-release again. Ran into problems when updating where everything was labeled as "Invalid" but messed around with things and got past them. It appears I now have a fully updated Moonraker install.
Ready to move on to connecting the Pi to my BTT Octopus Pro and then wiring up the printer.
I'm at the 'Printer Selection' option in the v2.4 Setup Wizard.
As I mentioned earlier, I have a SecKit CoreXY printer with about a 300x300x300 envelope. It has four stepper motors. X, Y, Z, Extruder. I'll be using the BTT TMC2209 drivers. Also has a BL Touch probe.
Question: Can someone please recommend which of the existing printers I should select to start with that most closely matches my setup ?
Thanks again.
Jay
