As i have 2 post related to this machine, i am copying what i posted in the other in case someone only monitore one of then:
“Hello,
i was testing calibration of my Babolat VS3001 during this weekend spending a lot of hours but now i am able to understand the process.

first of all, thanks to all the people that help me or at least tried to help: @abllee2198 @Babolat Official @Mike345 @fritzhimself @Irvin @jim e @jeroenn @Hankenstein

here my explanations:

i don´t know if someone had the same problem or could know what is the cause of this error (by double tension). Maybe is something more complicated than simple things but if someone has any idea i will appreciate so much

thanks for your time, hope explanation is clear”

The only thing that I can think of is that the strain gauge maybe damaged or the loadcell beam has been over stressed and lost some of is elasticity. the aluminium section is not returning to its original shape. did the machine have its carriage transport bolt in it when you bought it?

Thanks Mike
Transportation was done without the bolt...maybe the load cell is damage but strange that value is exactly the middle.
I am going to check with the electronic engineer if he has any idea.
I am going to test the machine this weekend and check again if value is really double of the display to see the accuracy day by day.
For me is something of how the machine convert in kg the value of the load cell. But i am not expert

Just a thought. Did you try setting all three potentiometers to the middle of there range. Count 20 turns counter clockwise then 10 back clockwise. Pot 3 next to the head needs to read 0.9 volts secret button 4 should read 000, then try calibrating the pulling tension, if you can do this whilst having a test meter across the gold pins you will notice you have to balance pot 3 and pot 1 adjustments against each other. Do this set to 60lb or 27kg.

This may cheer you up, if the load cell is damaged.
I can now get the load cell repaired, its possible to fit new strain gauges to the beam load cell.

As long as aluminium load beam has not been bent or over stretch.

I'm looking into getting new beams CNC machined but will need to see if this is cost effective with the cost of fitting the new strain gauges as well.

I have a machine here with exactly the same issue (although this one is going about 10 kilo's above calibration). I've replaced the flatcable (these are known to delaminate and die), I've switched the offset board to exclude issues with the measuremnets / amplification and it made no difference. This weekend I will replace the loadcell as it's likely broken. @Mike345 Do you have the specsheet for the replacement straingauges? Reason I'm asking is that I'm in contact with a cell manufacturer and I may have them do a run of cells to get a bunch of these babolats working again. They can take it from an existing cell, even a broken one, but an actual spec sheet would be best. Creating the aluminium bars is not an issue, it will take 5 minutes to program the CNC and cough up enough of them to sink a battleship...

I do not have the spec as i called in favour from a company I do work for. They sent mine to a "supplier who makes load cells. It came back sealed but I believe they used two half bridge cells to make it up. I can ask if they will give me the spec. What country are you in?

I'm in Holland. Right now I'm using the service of a guy in Germany for a loadcell repair, but he's been doing essentially the same routine: he found a company to repair or replace the strain gauges. It's pretty expensive though. Given that there are tons of machines waiting for a new cell, I want to try to get a bunch manufactured. I could even go to a Chinese manufacturer if I can get all the specs sorted. Chances are it's cheaper and the quality would probably be a lot better than what Babolat used 25 years ago..

How much is he charging?

I checked in CN and they can do 10 units minimum and price is 40 USD per unit.
But we need to send specs to be sure that works. Shape and sensibility at least

To manufacture the beam is really esay and cheap. I have a 3d model and i can do it my milling in CNC for some units with low cost

the load cell on 3001 looks identical to the one used on my star 4. I am pretty sure everyone who has star4/2502 will be interested to have one extra loadcell as spare parts.

Hello
Yes, that is the point. I have checked with Babtec in France company property of Babolat if they can supply the data sheet but they refuse to give to individual people. Mean that not possible to access to this info. They have but they don’t provide.
If we don’t have this specs, it is a lottery to make a new load cell due to different parameters that have to be taken account in the manufacturing process.
Picture of the load cell CR40 ( by the way in the new machines they use CR50, probably range 0-50kg instead of 0-40kg on old machines)

The gold colored one is a gravity release base. I am testing it, it is much nicer and easier to use than the original one.

I will definitely want one load cell as spare part though my star 4 still works fine.

It looks like you modded the adjustment wheel on your Yonex/Kimony starting clamp. Would you be willing to elaborate on what you did?

From where did you source the gold gravity release base?

the starting clamp is not kimony. they are new products from the same company that makes gamma and alpha machines. I got them from a recent trip to Hong Kong. The starting clamp is $50, the base clamp is $90.

hello @Mike345
did you be able to make new load cell? it would be interesesting for me. the beam is not a problem to make it, the point is how to fit the new strain gauges on it

thanks

I was in talks with a company in the UK who are able to make them or get the specs from a good one. (probably even a faulty one). If you can do it for 40 bucks, I'll take a few for sure.

Close to 300. It works though, you can see they replaced the strain gauge and the machine works ok, calibrates almost as original (it's a little off but not much).
If the rest of the machine is ok, I suppose it's worth it. This one went into a 3002, of which I also replaced the carbon brushes ( a few cents) and flatcables ( a few dollars).

Requires a starting / flying clamp.
Yes but i do tension in 2 strings at same time then, where i have to put the starting clamp and the fixed clamp??
And after how do you continue?
Yesterday i did what i do everytime but the starting clamp jumped out of the frame

hi all!
is there a way to find a babolat star 4 load cell?
my cables from mine where ruined. the body is ok but now it left with only 2 wires on it.

Probably not. I think @RJYU at Priority 1 has been buying old Star 4's just for parts to keep theirs running. Maybe he can chime in.

Hi I have a babolat star5 with a damaged load cell. I also need the load cell specifications.

Hi Claudio,

Where are you located? The load cell for the Star 5 is still available, so you should be able to order one, depending on where you live. I'm based in the US, but can refer you to the appropriate person if you aren't in the US. I do not have the specifications unfortunately.

Josh
 
hello Josh. Thank you very much for your reply. I looked on the internet and didn't find the company that sells the load cell. Could you give me the link to this company?

Thanks Fritzhimself and Irvin

I am making a mechanical revision and which functions are working.
This 2nd hand machine was offered me for 50€ and i see that all functions are working except: brake due to the use (i need to make a new one part with more thickness) and the linear pulling (i need to see the engine that activate the chain)
The rest is working well:
Magnetic clamp support ok
Knot function Ok
Speed ok

So i need to check if i am able to solve issue

Some pictures

Hola Galicia, acabo de incorporarme al post y he visto tu mensaje. Yo tengo una Babolat igual a la tuya y funcionando perfectamente. Por si aún no la has reparado, creo que tengo la dirección de un técnico de Madrid que puede solucionarte el problema

Is it
Hi Galicia,

Sorry I am replying so late. Please dm me your email and I will send you what I have as far as schematics. I wish I could help further, but I have never worked on these machines.

-Josh
[/QUOTe
Is it possible to have the schematics too?
I was given a babolat vs3001 and its not pulling too. I am taking it apart now. The motor is working as its returning to the start position but then it beeps when i push the button but doesn't start. Also the buttons for the magnetic clamp and the rising of the pulling head can't be pushed on the control unit.
I also need the codes to run the test so I can try to figure it out .
ALL help is appreciated
Santoriniwebmaster@gmail.com is my email.
Thanks guys

Yes secret key +4 should read 000 if the unit is calibrated correctly. the machine will not do anything if it does not know the position valve of the pulling head just a single beeb and does not move. Like you I have spent hours trying to find the information and then calibrating it.
Hello guys.
Where can I find the secret codes so I can test the vs 3001 that I have

Dears,

First of all thanks for your comments, i will be here to help others as much as i can
Today we assembled the machine and everything is working well. Nothing is damage and all the functions are working includind the motor that goes up in de diabolo but not when the arm of the racket is over it
My next step is to understand how to calibrate the tension. I followed the instructions received from babolat but without success. We were able to get 20kg when machine has 10 and basically receive double of the tension that we have in the display. For me something missing in the information.

But sometime ago I received one e-mail from Mr Fritz (thanks a lot my friend) with instructions from Mr. Schwank expert in these machines with a different info to calibrate. I will test them this Thursday and will let you know if it works.
If is ok i will share with all of you

THANKS to all of you for your help and support
Hello.
Is it possible to forward it to me at santoriniwebmaster@gmail.com?
Kind regards George
