Hi guys

Well i just published my new project: "BLV mgn Cube" on Thingivers.com

EDIT: The Project now has a new home: https://www.blvprojects.com

It a kind of Open source project with all the CAD files and the necessary assembly instructions.
You will find there many pictures, videos, animations, PDF files, firmware config, profiles and more..
I would appreciate if you could please click on the link and tell me what do you think about it.

Special thanks to David @dc42 for his tremendous help and Tim from Filastruder for his support.

Thank you

i have been asked a few times, how to to use 12V fans on a 24v system.
Although Its a very simple task, yet i have found no easy wiring diagram, so i made one.
I hope it could help someone:

I have to say that David's mini IR module is the best height sensor to use with the duet board. I am getting the most accurate readings..

so i am not the only one who is getting this behavior
same situation here, it deploys randomly right after probing with the 2.02rc2
on sunday i'll get my bud touch sensor just to make sure its not a bad one.
cables are fine, no shorts or disconnection.
thought about adding some delay or fast dropping the bed before it will bump it.

@dc42 said in Bl-touch re-deploy after probing or z homing:

Please run M558 and check that it reports you are using Z probe mode 9.

I can confirm that my friend's bltouch is acting same. even changed the wiring and its beeing deployed twice - at neer 30% of the probing points.
2.02rc2 on mode 9 too.

And again offline
from some reasone, I can't send you a p.m

@dc42
Nice, I Would like to test it too on my BLV mgn Cube project and adapt it to the project
I tried to send you p.m but you are on DND mode ..

at a build plate of 500 i would expect that the 2 rails would not be enough to ensure the stability of bed.
you could modify the build and add 2 additional rails and obviously the front panel would not fit anymore.

if you are not comfortable about doing your own mods you could have a look at the voron 2.1, which allows for such build volumes

@Warren-Abraham
For bigger bed plate i would recommend adding one more rail (3 z axis setup) and using auto ture leveling. It will be much better then using 4 rails. (Installation of 4 rails is a nightmare)

@mogal before i published the project, i had to run countless software simulations, hw tests and so on.
Using 2040 is very crucial for the rigidity of the frame. Unfortunately, at least two of the guys that tried to use 2020 instead of 2040 had massive ghosting/ringing and problems related to frame changes.
I would advise you to stick with the original frame design..

98% of the project step files can be found there.

Great respect to your work!
Your doku is really good and you have really put in a lot of time - no children and no woman at home

Thank you, you will be surprise to know that i do have wife and small children..
Making it took tons of time, stress and angry wife.. but it was worth it

Great looking project! The finishes are looking amazing on the sample parts.

One question, I looked at your S3D profile, you aren't using relative extrusion? Any reason why you don't use it?

@timcurtis67
I got to point that it the print quality was good for me, However i guess that when
i will have some free time - changes can be made

@veti said in BLV mgn Cube - 3D printer Project:

very nice. I wish your design had been done before i build my corexy.

how does it compare to your blv AM8?

have you tried the robotdigg mgn rails? i had some problems with my rails from CNA Mechanical Parts Store

@Veti
Honestly, both are good although the moving bed was a bit less optimal for bigger prints.
Also, the robotdigg are excellent as long as the measurements are the same as MGN12H
