What video?I cannot see the video
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 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...
How much is he charging?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..
I will definitely want one load cell as spare part though my star 4 still works fine.
Continue with the subject of calibration, if someone has the load cell broken; we need babolat to give us the data sheet.
Do you know if possible to get specs of the load cell of CR40? If not is it possible the data sheet of CR50? THANKS

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.

Hi Galicia,
I will reach out to Babtec and let you know if they have any information for you.
Josh
hello Josh (@Babolat Official)
did you find any data sheet or didn´t have time to reach out with Babtec? if you need some contact info like mobile phone and name i can provide you but of course in a private post.
thanks for your reply
Enrique
How much is he charging?
Requires a starting / flying clamp.How do you start the mains in your babolat 3001? Nice to know
Yes but i do tension in 2 strings at same time then, where i have to put the starting clamp and the fixed clamp??Requires a starting / flying clamp.

can anyboy tell me if the circuit on the load cell is full bridge half bridge or quarter bridge?
Hi I have a babolat star5 with a damaged load cell. I also need the load cell specifications.
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?
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 problemaThanks 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
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
Hello 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.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
