Manta M8P and CB1 or RP 4 and FYSETC Spider?

[sonoffire65]

Brand new here and considering building a Trident. The Formbot kit I'm looking at getting includes the Manta M8P and CB1, but looking at the Voron assembly guide and parts list it uses a RP 4 and a Fysetc Spider board. I have a spare RP 4 4gb, would it be worth buying a Spider board for $60 and using those, over the included Manta/CB1? Would there be a notable difference in performance or usability (or ease of wiring?) etc that would justify the extra cost?
Thank you!

Fysetc boards have a bad reputation of being finicky and stopping working out of the blue, specially the Spider (don't ask me how I know that). I'd go with a RP4 and an Octopus board, also from BTT like the Manta. The CB1 single board computer have a reputation of not being able to handle Klipper very well (you could use a Compute Module from Raspberry Pi though). I also remember reading people having problems with Manta while others swears by it, so it's kinda of a mix opinion (one that I can't give my personal experience, so I'm only replicating what I have read).

tl;dr:

• Spider boards are not reliable;
• Manta boards are ok, but avoid CB1 (or CB2), use original Raspberry Pi CM4;
• if you want to use a common RPi4 on your printer, get an Octopus board.

Thank you! Ordered the trident kit and the octopus board was on sale! Nervous, I have a lot to learn, but I'm excited!

I have their spider and cheetah boards. I've not had any issue with either, but I wouldn't choose them if they didn't come with the fystec kits.

Only issues I've ever had with boards is when I messed them up myself. Except...one time I had a bad Manta that was quickly replaced. Not sure what the issue was on that board?

My only CB1 works well, but I'm going to change that board to remove the CB1 and replace it with a pi. I don't like the single USB you are relegated to by using the CB1.

I've used almost every board out there, and they are all pretty similar. Just go with something that has been around a bit, and you'll have fewer issues as there is more documentation.

I second the above rec: Octopus pro, pi5, usb/can extender...if using tons of mods.

Nothing wrong with CB1 and Manta M8P though...if you choose that route, just know that you'll be limited on addons unless you throw an extender on it, though you'll probably edge up against that no matter which board you choose, I did...several times. And the image is finicky, at times, from BTT...as is a lot of their stuff.
