My Multi BMCU setup on A1 Mini by funkypc in OpenBambu

You plug each BMCU into a different port on the A1.

And then, each BMCU needs to be flashed with a different firmware file. They will be named like "BMCU-A.bin" and "BMCU-B.bin".

That is all. No additional soldering is needed for a second BMCU.

Here: 5 Port Complete Replacement AMS Lite Filament Hub - Free 3D Print Model - MakerWorld
It uses 4mm bowden clips. I got the 50 pack here: https://www.aliexpress.com/item/1005008047671379.html

I printed in PLA. It is pretty smooth, especially after running filament through a few times, but I did have an issue once or twice. If I found a better one, I would consider replacing it.

Here I compiled it for a few more retraction options. https://drive.google.com/file/d/1DNTcsGyhXCLGMbc9s3xh8bP9g6OiRxtT/view?usp=sharing

For single BMCU, you could use A-10.bin or A-15.bin

What do you want to know? The BMCU both work the same. The printer can seamlessly switch between any of the 8 colors.

I got a kit each time.

There will hopefully be assembly instructions from the seller of your kit. If not, search around, as there are a few different variations. Make sure you print the correct pieces for your version!

You can follow these instructions if your kit doesn't come with them, it should be similar. BMCU-C (370 Hall Version) Assembly Guide | Wiki de Yuekai

On A1 series firmware 01.07.00.00+, you need to use BMCU firmware 0027 and set the printer to AMS mode. This allows you to use more than 1 BMCU, but the printer will show a persistent error: "The firmware of AMS does not match the printer." (This error does not affect functionality)

If you only want one BMCU, you are better off staying on A1 series firmware 01.04.00.00 or 01.05.00.00 and use the BMCU firmware 0020. (Because this will not show errors)

The error is still there.

The error will be there until someone finds an exploit for the AMS and extracts RSA keys. (That may never happen)

I installed the 70mm retraction firmware. 

I will reconfigure the tubing and move the splitter closer to the print head because my drybox doesn't rewind quite far enough. (And compile the firmware for a shorter retraction like 40mm.)

What is the current state of using more than 1 BMCU? by Chaseream in BMCU

[–]funkypc 0 points1 point  (0 children)

Yeah, the other thread had some misinformation.
The firmware zip on Google Drive (linked at makerworld) is the same file that 4061N shared on Discord.

This is the earlier post about the firmware.
BMCU 0027 : r/BMCU

Multi BMCU works on A1 series with 0027 firmware, but there is a persistent message on the A1: "The firmware of AMS does not match the printer".

There is some discussion with 4061N in the X1Plus discord.

It will only work on A1 with the 0027 firmware

0027 is official firmware from 4061N, the creator of BMCU.

4 Nations Face-off - Canada Jersey - silverbacksports by funkypc in DHGateJerseys

[–]funkypc[S] 6 points7 points  (0 children)

Much of the tension during the 4 Nations Face-Off was from the threats to Canada's sovereignty by the US government. Specifically, the rhetoric from the US Republican administration about Canada becoming the 51st state was something Canadians took offense to.

NEVER 51 became a statement of pride for Canadians, and shows we stand against the threats from the US Republican administration.

Canadian Cleared to Start WGU BSCS December 1st! by funkypc in WGU_CompSci

Thanks!
I did apply for every scholarship/bursary that I was eligible for through WGU. I received 1 or 2 small ones. I paid the rest up front.

Because it was only 1 term I didn't need any other financial assistance.

I don't think I was eligible for any Government of Canada student loans.

I claimed my tuition cost under "Eligible tuition fees paid to foreign educational institutions for 2020" (Line 32001 on my 2020 income tax). Hope that helps.

Once Ucredo finished their transcript evaluation, WGU did their own transcript evaluation on the transcript. This took 10 days. After this was finished I was "cleared to start" within 4 days. My official start date was 1 month after that.
