Which control board to choose for 3.1 500?
Hey Guys, i lived in the marlin and duet world - until now. I would like to try ratOS but have no clue which board to choose. The possible boards are shown in the ratOS documentation, but bigtree techs website didnt help me too much to decide.
Which board would you recommend or even advise against?
Printer is an 3.1 500, fairly standard for now. lightweight CPAP VZ-Printhead, I want to enclose it, heat it to 70-80°C and print „reliable fast“, no crazy high speed. Money is not no object, but i‘m willed to pay for quality & reliability.
Thanks 🙂

octopus seems to be the most popular, followed by the manta
An Octopus Pro or a Manta M8P (get a CM4 instead of a regular pi in that case) will do everything you need it to, including high voltage if you wanna go that route right off the bat or later down the line.
Thank you both! The Manta M8P with the CM4 looks like a neat solution! How much RAM you recommend for the CM4 Lite? Did I get it right, that with the CM4 + M8P combo i‘m limited to DSI displays?
No you can use HDMI
and like 2gb is perfectly fine
Thanks mikl, i really wondered that btt states on their product page of the hdmi displays that they only work with the cb1 via hdmi.
Huh, well i'd trust the manufacturer over my memory 😂
DSI isn't bad though, in fact RatOS works out of the box with the BTT PiTFT DSI screens
@miklschmidt Why cm4 over cb1? Its almost 3 times more expensive and doesn't seem better?
CM4 runs the same RatOS image as the pi's, and i can guarantee the experience. Simple as that. Also i'm not sure where you're getting your prices from 😄 A CM4 Lite + Wifi 1GB RAM is 40 euro locally, plenty in stock too. They're roughly the same price as Pi4's.
The CB1 is 23,3 euro, and there's a bunch of stuff that isn't supported yet.
and the cm4 is substantially faster
I'm under 25% usage on cb1 with a 720p webcam im also thinking about cm4 for my other manta but im not sold on it yet
I bought the bundle cb1 + m8p + 8 2209s for 96ish €, there the cb1 went for about 10 bucks compared to buying m8p + 8 2209.
What isnt supported with the cb1 by now?
There seems to be random wifi / hotspot issues. Works for some, not for others. I have absolutely 0 idea about screen support.
Keep in mind the RatOS CB1 image is a user contribution and is experimental
do any "pi" DSI touch screen work out of the box or is it only BTT PiTFT DSI ?
Maybe, but i can't make any guarantees. You may need the right combination of dtoverlay params, check if the manufacturer has instructions for bullseye on whichever version of raspberry pi you're using (they need different configuration).
Thanks... 👌 like things there just works.
