From The Bench: Episode 4 - Configuring Klipper for BTT Octopus Pro and EBB SB2240 MCUs

It looks so clean. Beautiful toolhead!

Very, very helpful video series. I was able to get my BTT SB2209 w/ BTT U2C working using your videos. Of particular note was that your videos show the wire and cable connections/disconnections along the way. Other youtubers were not careful in showing this and it makes a difference. BTW, You mentioned (maybe on discord) that your videos were long-winded but I think they are just the right length. Thanks again.

Hi, good video series, best I've seen so far and the most up to date. It really helped me out. Only one thing I could not get sorted out the neopixel LEDs. Can't get them to work :( Tomorrow I'm gonna check the wiring once again but all else in regards with the SB2240 works just fine.

Really helpful video, thank you so much for taking the time to cover everything so well. Could I possibly ask if you used any of the 3D printed parts from the BTT Git, and how you afixed the CAN cable to the toolhead and the other end on the carriage?

Thanks for the videos, I am using a SB2209 RP2040, Octopus v1.1 and U2C V2.1. Your videos were very helpful, and I was able to get all flashed and operating. I am having two issues. #1 what need to be done to connect the Octopus through the U2C? Octopus communicated fine when USB is plugged directly into the PI but will not connect when plugged in the U2C. #2 I am using a Rapido V2 with PT1000 RTD. The BTT sample Klipper cfg is for the SB2240. The sensor_type: MAX31865 appears to very different for the SB2209 RP2040. would appreciate any help on the Klipper configuration.

be careful with the 2240. i installed it and got undervolting left and right. it just cant handle my dragon highflow and fast printing at all. either it undervolts and dies, or it dies from having to limit heater power. switched to 2209 and my heater works flawlessly at full tilt. my only limiting factor now is hotend flowrate

What did you change the sensor type for the revo ?

What are the Molex connectors you have used to extend your Wires. I too use a REVO hotend?

Hi working also with Octopus not Pro?

I'm about to add canbus with the SB2240 and also have the Octopus. Is the U2C needed since the Octopus has a canbus connection?

im having an issue with the hotend sensor. Im using a slice PT1000 and have installed the jumper on the 2.2k spot aswell switching it to on on off on (as per 2 wire) and after updating in the cfg to a PT1000 it is still saying MCU EBBCan shutdown: ADC out of range. Anyone have any ideas? Am i meant to change the sensor pin for using the 4 port connector? and if so what should it be set to?
