no. The Pi uses the sensor_type temperature_host . Klipper knows to pull that from the local host.

Just noticed the klipperscreen install I did this morning is actually working. I haven’t been out to the shop with the printer running since this morning to notice.

This weekends goal (once the shop heater warms up) is to maybe, possibly try to get CAN working. I have the board. Last night I modified my wire mount to allow me to bolt the EBB36 to it. I have a bit more work to do with the CAD for zip tying the cables to it.
I need to hook the EBB36 up to the pi with all the other USB stuff unplugged so I can see about flashing it with klipper. I want to make sure I can read the ADXL and maybe make a fan turn on/off before I go to the trouble of clipping wires.
Oh… OH… And I really need to get the z-brake installed.

Putting this here for future me… Installing Klipper on the BTT EBB36 for communications over the USB port without needing a BTT U2C (although I ordered one of those too).

Yeah, this part wasn’t fun, fwiw shared (Jan 2024…) notes at https://github.com/aaronse/v1engineering-mods/blob/main/mp3dp-v4/sw-klipper-with-canbus.md

@Jonathjon and I have had a private thread running where he’s walked me through quite a bit. And, once I knew what words to search for, gemini has also helped a lot. Jonathan helped with the terminology and understanding. Gemini helped with copy pasta commands.

Hope your EBB36 works out great. My first one ended up being a dud and returned, gory details at https://klipper.discourse.group/t/canbus-query-py-not-returning-ebb36s-uuid-setup-pi-4-octopus-v1-1-ebb36-v1-2/8464
The fun part about using my own designed core is getting to design my own mounts for things.
I give you the over-complicated EBB36 mount. I wanted to try to support the EBB36 in as many places as possible without hitting any pins on the bottom. I also added some wire management for both the USB-C cable and the power wire I’ll be using.
I’ll work on getting this printed tomorrow. I printed a very un-complicated version of this today to make sure all the holes lined up. (Why wouldn’t they, it’s all done in CAD !?!?)
I think I’ll be losing a little bit of my X travel. I have a feeling the back of the core might hit the belts now.
One thing that still amazes me is how much faster this thing prints than my old bed slinger. Orca says this will only take 1h12m to print.

I woke up thinking about this in the middle of the night. I could reduce quite a bit of the mass if I get rid of the usb-c cable and go pure CAN. I did already order a u2c board.
I also ordered some usb-c breakout boards. Now I can decide what to do after all the parts get here on Tuesday.
I do know I want to print some strain relief for inside the electronics cabinet. I’ll start working on that design later today.

Dang it seems like a lot of space could be saved with solder pads. I know plugs are convenient but soldering wires to pads is pretty easy. And it would be a solid reason to buy one of those USB solder pens.

I’d question whether all the movement would cause a solder pad to be broken off. At least with the plugs it’s a through hole joint.
I know wire strain relief will help, but still.

I don’t know what I’m looking at here, but I’m assuming the really big umbilical cord really makes these graphs bad.
The one thing I did understand is that the printer recommended lowering my acceleration down to 1800, which is a lot lower than the 6000 I previously had set.
Yeah thats WAY more cables than you need running a toolhead board thats for sure.

I’m still waiting for the USB-C breakout boards or the U2C to come in. I was just too excited to get it mounted and test ‘something’ out.

That I can understand 1000%!
In other news… My big, thick, aluminum plate I used for my heat bed has a warp in it and that’s why the one corner is always high compared to the others. I laid a flat ruler across the back from left to right and you can see light under the middle section of it 
I don’t have an easy fix for that, so I’ll continue taking advantage of bed_mesh leveling.
I’d have to either replace the entire bed, or at a minimum, the magnetic surface that’s stuck to the bed. I ‘may’ be able to flatten the magnetic surface, but if that went wrong, then the bed would be ruined. This bed was not cheap between the aluminum, heater, magnetic surface, and insulation.
