A project log for SecSavr Sublime [gd0036]

A 3D printer that I describe as "The FULL Coverage, Extended X, Pro Max, Ultramatrix Solution".

The new board is finally out: https://www.aliexpress.com/item/1005004478452192.html

As expected, it's over 170mm in length. Seems that it'll be closer to 180mm.

There isn't yet a listing for the Manta M8P by itself, but looking at the M4P, I'd assume that it'll cost £46, which is currently a tad under the Octopus Pro.

Now there are some notable features on the OctPro that aren't on the M8P by the looks of things:

Notably, the CPU is over 100MHz slower and I can't see any CANbus headers or port. The red cover for the input terminals does look more refined than the orange ones on the OctPro though. Hopefully the STM32G0 is still fast enough to send signals for 6 steppers simultaneously.

Knowing this, it seems that there is almost equal justification for M8P+OctPro or dual M8P, though I don't think Klipper supports toolheads using the OctPro CANbus at the moment so dual M8P might be better if I didn't already have an OctPro.

As for the CB1, the standard price is a tad under the price of the Orange Pi Zero 2, which has the same H616 processor and 1GB of RAM. There's also an optional heatsink that covers the whole thing for another £5.
