Give a beginner the right advice, i have horn yuichi a290, and driver bms 4590, what parameters should I put in the calculator to get the highest quality sound for classic jmlc horn
I want to try something new and compare yuichi, well, I don’t know what parameters to set in your calculator.. совсем другие рога! jmlc будет излучать больше. если тебе нравится Юичи, лучше попробуй mk3b2.

Hello Docali, I downloaded this calculator
JMLC inspired calculator (HVDiff):
Version 3.04 (12/2022): DrBA_JMLC_V304
What actions do I need to take to import calculations into Fusion 360?
I created a model in Excel and saved the txt file drba_xyz.txt, what should my actions be in order for me to open it Fusion 360?
Best regards, Dmitry

The .CSV files are the splines. You need to enable the splines output if not already.
The python scripts are also included. You need to copy this to the f360 scripts folder. But this is Fusion know and you may look elsewhere how to do that.

Some impressions of the new wn300se made by LMH:

What steps do I need to do to enable slimes? I don’t understand how to do this. Could you tell me step by step? What do I need to open where to click What programs to have Fusion 360 I haveФайлы .CSV представляют собой сплайны. Вам необходимо включить вывод сплайнов, если это еще не сделано
Best regards, Dmitry
Hello,
you need to set "Export Splines?" to "1" column "Q"
And then read this:

I can’t understand the algorithm of my actions. Could you record a video or send screenshots? What actions should I take?Hello,

I also read your article and there is no action algorithm there either.
What list of programs should I have?
Python is ready, downloaded, what next? horn I already calculated the text file drb_xyz recordedI think you need python installed.
Generally, it is beyond the scope to teach people how to use Fusion 360. The web is full of infos and tutorials about this.
But when you have opened F360 then click Shift-s to open the scripts window.
You need to identify the local installation scripts folder by clicking on the green plus sign (for me):
C:\User\{UserID}\AppData\Roaming\Autodesk\Autodesk Fusion 360\API\Scripts
Then copy the two folders with content here.
The next Shift-s should look like this:

Start to import the splines (you need the *.csv files). Be patient!
When ready, start to loft the splines.
The resulting body is not closed. You may need to patch it for further processing.

Now, I found the time to write the corresponding article about Adam's diy project:

I want to express my deep gratitude to Dokali for helping me understand his calculator, for the fact that he basically created the site and runs a blog.
I even bought myself a CNC machine and figured out 3D modeling and in the preparation of control programs for CNC.
First I did Yuichi arai 290hz
, then I will make yuichi arai 470 Hz
,then i made 470 Hz but glued it the other way around\
then i made a spherical one
bass cabinet mine looks like this this is the transmission line tuned to 35Hz
BMS 4590 driver, bass speaker custom
so what i want to say is a spherical horn - this is my maximum sound, it is precise but narrowly directed, So all these yuichies go to the trash, the spherical horn gives so many micro nuances that yuichi never dreamed of, Thank you very much for giving ordinary people the opportunity to develop their own inventions and all this for free. I wish there were more people like you in this world.
With sincere love from Russia.
