Hello BTT folks, some clarification on the probe issues would be most helpful. This is confusing, as the new port was meant to be better suited to this kind of probes.

it's a good idea to at least bore holes through board on caps connectors so enthusiasts can replace caps themselves placing them on back side of board: actually it's impossible to fit SMD caps with bigger voltage on face side of board while holes can be bored in newer revision w/o any issues(ofc if there's no traces under them)

@@SergeiSugaroverdoseShuykov I think having through hole ones sideways like some Arduino CNC shields do could make that possible, but that would of course make them stick out further to either way and thus the jumpers go somewhere else, either jumps or caps have to move.

nice review. I'm really tempted to replace my two SKR with one of these. It's just so clean and has so many controlled fan outputs for all kinds of shenanigans

One small observation. The header that you called out above the fan ports is an SPI header. For the Raspberry Pi connection, both serial and power come from the "UART" header directly to the right of "MOTOR7". There are 2x5v, 4xGND, and TX/RX in a non-pi standard orientation (unlike the spider header layout that matches the Pi's). If you are going to use this header, be mindful of the pin layout in your jumper as to not damage your Pi or your Octopus. If you plan on using UART instead of USB, you will need to setup the firmware to use "Communication interface (Serial (on USART2 PD6/PD5))".

Great review and information; one thing the wrong connector pointed to for Raspberry Pi, the correct connector is next to the I2C connector.

I just got an Octopus v1.1 after the extruder driver on my SKR e3 mini blew up randomly. It’s gonna be my first board that’s not a plug and play swap. It’s gonna be an interesting learning experience.

The spider actually supports 6 Fans, only 3 are "dedicated" fan headers, the other 3 are multiuse headers that can be fans or LEDS for example. And of course any unused hotend heater pins can be used for fans too.

Impressive video, I’m stuck with my Voron build, well maybe not stuck, this board has 2 sets of outputs for the bed, one is marked bed power and the other is just marked bed, I’ve never had a SSR before and think I should connect to the bed output and not the bed power. Is that right?

Great video! I'm kind of new to all this but tinker with everything form time to time. One question I couldn't find answered anywhere is: If this is suitable for the Creality CR10 Max? I've read that other boards from BTT are not suitable because the CR10 Max has 2 separate PSU's that couldn't be wired correctly. I'd buy the Octopus in a heartbeat if it can be confirmed compatible with the CR10 Max setup. Thanks in advance!

About probe port: I'm using octopus pro board which is basically the same. It's fully working using OMRON and similar probes. It requires special tune in configuration.h! You have to disable pull-up for Z_MIN_PIN and then enable pull-down for it.

Would actually want larger than 50V caps for 48V motor power. Those bulk caps tend to loose a significant amount of capacitance (up to 50% in some cases) due to DC bias. I would argue that the 35V caps used are correctly sized for 24V.

Really enjoyed the video and this will help me with getting my 2.4 unit operational. I would like to share a caution. When handling circuit boards with ESD (electrostatic discharge) sensitive components, please consider using an ESD wrist strap and mat that is connected to an earth ground. Watching you touch pins and connectors made me cringe as low voltage discharges, which you can't see or feel, can weaken the internal structures of IC's and other devices. This can shorten the lifetimes of those parts and cause failure a few months down the road. Anyway, just passing along a tip to help keep printers up and running.
