BIGTREETECHOctopus V1.1 Control Board 32bit Silent Board Compatible TMC2209, TMC2240, TMC2208, TMC5160 Stepper Driver, Support DIY Klipper and Raspberry-Pi Online Printing for Voron 3D Printer

I'm converting an Ender 5 to have 4 extruders and a Zonestar M4V6 4in-1out mixing hotend. Most mainboards don't have at least 7 stepper drivers (X,Y,Z,E1,E2,E3,E4), but these do. You'll be building your own firmware for it, which will be a bit of work, but once you have it all set up, it'll work great. It'll give you more ports for doing dual Y and/or Z too.If you haven't done your own Marlin firmware before, it'll probably take you a couple days to go through all the decisions on where to put things, and configure the Configuration*.h files. Not impossible, just a little time consuming. It doesn't even require programming, just the ability to read plain English words, and pick the options.The biggest caveat that isn't documented is, you have to use a small SD card with it. It can't read any of my larger CF cards. That took me a while to discover. I'm using a 128MB card, which does work. I really don't have many cards less than 32GB, so I really had a hard time finding one. So when you can't flash the firmware, or read the card for gcode, go get a *smaller* SD card.

I was happy with this CAN adapter. I used it to help isolate a CAN bus issue I was experiencing with one of my Voron builds (I used it to bypass the on-board CAN bridge on the Octopus board). In the end I ended up leaving this board in place on that build, and it has performed without issue.

Using it what it was intended for, a way to add CAN bus to my Voron2. Connected 24Vdc to power it, routed it to my PI via USB, wired CAN TX RX to the toolhead wires provided for my EBB RP2040 from BTT. Was talking to it as soon as I configed my PI using Katapult software.Make sure you go to BigTreeTech's GIT page and download the assets for the project used in conjunction of whichever path you chose for upgrading your toohead.

This Company comes up with the products you want, but other than the hardware, everything else is lacking. Their support for their products is spotty at best! You are basically on your own to figure out how to make their products work(even in conjunction with their own products). Their customer support is hit or miss, and they often show product in stock that in reality aren't. This results is unknow and uncommunicated delays, and when you finally realize you have to reach out to see where your stuff is, the response is very apologetic, but lacks any real information or details about when you might actually receive the parts they originally told you were in stock and ready to ship. Again, Good hardware....Bad everything else!!

This is installed in a Voron 2.4 350x350 and a voron 2.4 r2 500x500 its a great board and is easy to work with in klipper have not used it for marlin but nowadays who uses marlin?

I wanted to upgrade my 8 bit Anycubic Mega X board to a 32 bit board. I needed 5 motor drivers, but many of the boards only had room for 4. I considered the Spider but for about the same price decided on the Octopus. I was going to install Clipper so the added plus was that the BTT board had great documentation made it the logical. I paired the board with TMC2209 stepper drivers in uart mode and once wired up everything just works. Still have some tuning to do, but I am pleased with the way everything has worked out.

The best upgrade I’ve made yet. I out this board in my ender 3 and it is wayyyyy over kill.Installation isn’t bad, but setting up the firmware is not beginner task, but is doable with patience. I found that configuring the firmware was a pain, because their is no config files for the ender 3, but uploading the firmware to the board was actually less difficult to do than with the creality boards.

When I got the board it appeared to have a working Candle already flashed so I happily moved on to flashing Canboot to the EBB42 via USB and then reconnecting the EBB42 to the U2C via CAN, attempting to flash Klipper via CAN and failing. Drove me nuts for a couple of days. Then I got help that told me there was a bug in the Candle that came on the U2C and I needed to flash the latest version from BTT github. Once I did that I was able to successfully get the EBB42 flashed and everything working. So save yourself from lots of aggravation and update the U2C right away.

I updated to firmware first thing, then was able to use it with my EBB with no issues

Had problems connecting btt manta m8p v1.1 board to canbus this fixed the problem somehow.👍🏽

Worked with klipper right out of box, only thing if using canbus over USB (SKR3 mini e3 for example on PA 11/12 make sure to use VBUS jumper on the u2c (for respective port 1/2) the manuaal sucks but the product is amazing, came flashed with candlelight zero config. running EBB 42 MCU, SKR3 mini E3 MCU, and RP2040 with can transceiver running my filament heater box/ filament sensor, and ventilation/dampers
