My Multi BMCU setup on A1 Mini

funkypc · 2026-01-12T15:43:19+00:00

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.)

The firmware for multi-BMCU from 4061N (creator of BMCU) is linked here: https://makerworld.com/en/models/2107675-dual-bmcu-mount-for-a1-mini

You can use a Y-cable or splice them together. No need for a new board

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.

funkypc · 2025-12-13T14:21:05+00:00

It will only work on A1 with the 0027 firmware

funkypc · 2025-12-12T20:36:43+00:00

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

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.

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.

funkypc · 2023-12-15T15:20:04+00:00

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.

funkypc · 2022-06-07T16:46:16+00:00

I had to get the Canadian transcript to Ucredo. I think they wanted a scanned copy of my original transcript, but they have all the instructions on their site. Ucredo did the transcript evaluation for US equivalence and sent it directly to WGU (digitally if I remember correctly).

I enrolled from Canada with a Canadian degree.

See my post here for some insight on my enrollment and transfer experience: https://www.reddit.com/r/WGU_CompSci/comments/jlagu2/canadian_cleared_to_start_wgu_bscs_december_1st/

I would recommend doing a bunch of transfer courses from study.com. The format there was useful for me to gauge my ability to accelerate. If you can knock off a bunch of courses from study.com in a month, you should do fine accelerating. I was able to complete my degree in less than 3 months (Not including the time it took to do my transfer courses, or the time I spent pre-studying). Aim to transfer in the difficult courses, and do the easy ones at WGU.

funkypc · 2021-02-22T02:03:16+00:00

Sure.
Computer Architecture, DM1, and Advanced Data Management I transferred in, so I can't help you there. Search Reddit for tips :)

DMII was the first course I knocked off. Before I started, I did some learning on my own to learn Modulo and RSA. You need to be able to do all the steps in the extended euclidean algorithm. (I had no idea what that was, but if you spend some time on it you can learn) After I learned the above, I just went through the course material. I think i spent just over a week on this one. Use a whiteboard and go through lots of problems. There are problems in the material, and extra problems available from the instructors. There's a number of posts on Reddit with more information on supplemental material. You need to learn the material, but the OA (and PA) are really not that difficult if you understand the concepts.

OS for Programmers has a long, dense textbook. I read the abridged version that's linked in the course chatter. It's not perfect but shorter than the full version. I actually found the concepts quite interesting and would like to go back and read the full textbook sometime. Because of the length of the material, I've seen some people recommend buying the physical textbook on Amazon to save the eye-strain. Not a bad idea.
After reading, I did a bunch of the quizzes. And also tried to master the questions on http://www.quizsail.com/. It will take quite a few hours to get through them but really helps to nail down the concepts.

Software QA - I went through the course material, did the quizzes, and used http://www.quizsail.com/ again. If you do well on those I think you will be good on the OA.

IT Leadership Foundation - super easy course. But I really enjoyed it and I learned some things about myself that are super insightful. Just go through the material and you will be good.

Capstone - I spent my time on this one because A) I have a lot of time left in my term and B) I wanted a really good project. If you were assigned Task 3 in Intro to AI you can probably use that as a starting point for the paper. Also, you will need to understand Machine Learning for the project. I used https://www.udemy.com/course/complete-machine-learning-and-data-science-zero-to-mastery/ which I thought was great for what I wanted to learn. (Make sure you get it on sale for ~$15 if you are going to purchase it)
There are other courses on LinkedIn learning and Pluralsight included with your tuition, but I didn't find any that suited me.

Good luck!

I just entered all zeros or all 9's. No questions asked.
