PRO STRINGER Platinum 2.0 stringing issue - constant clicking

Looking for inputs/suggestions from any PRO STRINGER users out here who might have encountered similar issue.
When you press the button to pull the tension, it should stop once it reaches the desired tension and the light should turn green indicating that we can clamp the strings. But with this issue, it seems that it constantly keeps adjusting the tension and the dial (not sure what the technical term would be for this...but I am referring to the thing that holds the string while it's being tensioned) does not stop for 2-3 minutes sometimes (that's the most I have waited anyways...any longer, I have to forcefully hold the dial so it would stop clicking). I would say for the first 9-10 months of me owning the machine I did not have this issue. Since then the time of clicking has been going up. It is annoying but I could live with it if tension was reliable but tension is never accurate or close to desired tension.

I have tried to wrap the string around and then into the holder to see if it makes any difference but it did not help. I had reached out to their customer service and they had given me some PDF for the instructions to open the machine and make some adjustments but that did not help either. I had a video call with them to show them the issue and on the first string itself when it happened they said we will have to send this to Korea for servicing but they backed out of it later saying this is normal and machine is just adjusting tension. All other attempts to get this resolved from PRO STRINGER has not worked out so reaching out to community here.

Thanks !

@TennisShishya,

Disclaimer: I have ZERO experience with the PRO STRINGER, so this is just a "best guess"/speculation on my part.
So, take that for what it's worth (which ain't much). :cautious:

What you've described sounds like it could possibly be the eCP load cell(s) going bad.

Hopefully, more knowledgeable people than myself can give you more reliable/better guidance.
I'm tagging @abllee2198, @Geoff, & @Sardines in the hopes that they might have some idea what's going on.

The disheartening part is that (it sounds like) their customer service dept. is brushing you off. :confused:

Hello @TennisShishya

I would contact JC Carpentier at TennisMachines.com. He is one of the best in the country at repairing stringing and ball machines. He will spend time with you on the phone and be honest on what can or should be done as the best course of action. I have used him several times with 100% satisfaction.

Agree...sounds like a load cell(s) issue to me as well. And you hit the nail on the head about their Cust Svc...speaks volumes. To even fathom this stringing machine now is showing 'normal' behavior is ludicrous at best. I'm willing to bet had the individual here called Pro Stringer about ordering a brand new Platinum 2.0 machine, they would have had no problem helping him...find his wallet and credit card.

If your unit is less than 1 year old, it still qualifies for warranty. I would suggest reaching back out to them in the context of making a warranty claim.

Their customer service is only via email, facebook messenger or whatsapp. I am not a Facebook/Whatsapp user but had to install Whatsapp to get in touch with them. Customer service was responsive (within couple days) on Whatsapp and email; just disappointing that even after sharing multiple videos with them about the issue they kept saying it is normal behavior after initially acknowledging there is an issue with the machine.

You summed up my point exactly. If you explained to them that you used the machine for almost a year, as stated in your opening paragraph, and now this problem comes o' knocking, and they backtrack and tell you that this amount of time to reach setpoint tension is now 'normal,' I can only imagine what you'll hear next. I know it's difficult at this point for you since you have one of their machines, but I'd stay as far away from this Cust Svc clown show as you could in the future. Eventually buying another machine from a different mfg'r is prob going to be the resolution here. Threads like this are great, at least for someone like me...I'll never lose an ounce of sleep nor a dime with these Pro Stringer folks and their little portable stringing machines, because of this scenario right here.

And I'm sure this was not just some random, lone wolf gamble that you ended up with a Cust Svc guy who knows absolutely zero, this is par for the course Cust Svc nowadays with a lot of businesses. And to not have a simple telephone number to interact with, and have to join/get on some social media crap to resolve an issue(s)...I'll take my money elsewhere. Enough said.

From what you're describing, at least to me, it sounds like the constant pull mechanism at work. Usually it beeps once it achieves tension, then will constantly adjust to maintain that tension on the string. This adjustment usually happens once after a few seconds as the string stretches, or when you remove the clamp from the previous row. The more elastic the string, and/or the longer you take to clamp off, the more often it will do it. Now if it doesn't tension at all, that's a different and more serious matter. Otherwise, it's just the constant pull adjustment, which is a feature.
If you're saying it adjusts even after you've clamped off, then there might be an issue with the clamps. I suggest you clean and readjust your claws. Then do a test where you clamp off once it tensions, then see if it adjusts, to eliminate string slippage. If it's still adjusting after the beep, then adjust the clamp tighter and see if that works.
Btw, we've owned the machine for 3 years now and restring 2-5 racquets weekly. My kids have dropped it more than a few times, and it keeps on working. We have never had to deal with the technical division, so I can't comment on that. I have dealt with sales side on things like missing items and replacement equipment, and they have been very efficient and informative.

I totally see your point that it is a constant pull feature. My issue is that it goes on for too long most times especially when stringing mains; happens for relatively short time for crosses. When stringing mains, it keeps on adjusting tension and when it finally stops and I clamp it, it would start readjusting again (this is not often but enough to be annoying) and it does not stop immediately. Even after clamping it would go on for few seconds to a minute sometime. I have readjusted the claws to tighten it to a point that it does not leave any indentations on a string. I have not cleaned the claws though. I will give that a shot. Thank you !

I suspect it's your claws that aren't tensioned enough so it is slipping and the PS is just adjusting. Another way to tell if that is the case is to put your figure on the string near the clamp. If you feel slippage, it's the clamps not adjusted correctly. Also pay attention which clamp and which side of the clamp is slipping. The Claw V1 has alignment studs and if they aren't aligned from being dropped etc, it won't close properly on one side. I've made my kids strip down the claws every 3-5 months for a clean with alcohol, since I use silicone coated strings on the cross.

I don't think I can tighten the claws more then they are currently without it affecting the strings. I have definitely felt and seen the strings move after clamping when machine is constantly readjusting which I thought was because the clamp was moving as well. But I will pay attention on my next sting job as to which side of the clamp is slipping.

A good maintenance habit is to periodically clean the machine’s clamps and string gripper surfaces. My habit is to clean every 10 or fewer frames. More often when the string is greasy or oily. If I have forgotten the last time it was cleaned, I will clean the clamps and gripper.

I suspect it's too loosely tensioned. Most strings can take a little extra 1/8th turn to tighten the grip. My kid had an issue with stringing my frame with natural gut where she thought it was too fragile to be firmly tensioned, so the PS just kept pulling until it went round almost twice from the tensioner. Once I tightened the claws by 1/5th turn on the screw, it stopped doing that. Elastic/softer strings need a little more grip.

The Pro Stringer doesn't have anything as complicated as a Load Cell, it uses a spring, a balance beam and a micro switch to fine tune the tension.
I've had my Pro Stringer for 9 years now and about 2 years ago mine started misbehaving when the tension button was pressed. It would pull tension and then randomly release and retension(only doing this intermittently). The fix was replacing the tension button with a new on supplied by Pro Stringer. Hard to say if this is your issue without seeing it.

That's good information to troubleshoot. Does it pull tension and then the green light comes on, then it goes nuts? That is what I think the OP is saying is happening to his unit. Or does it never achieve green light tension, which I think is what you're saying happened to your machine when the switch went bad. Furthermore, if the PS tech peeps are looking at the behavior videos and think that is normal constant pull behavior, knowing issues like yours have occurred, although could be the tech the OP spoke to isn't the same technician you dealt with to troubleshoot your issue.
I guess we have to wait for the OP to come back.

One of my PS buddies has emailed me the videos of the problem and it is not same fault that I had. This is what I would do next.
You need to test the tension accuracy of the PS with at tension meter(weight scale).
This is the only way you will know if the PS is pulling accurately, if it is not accurate you will have to send it in for servicing.

As part of diagnostics with PS team, this test was also done using a fishing scale.
The fishing scale was locking at around 48 lbs when the desired tension was 52 lbs (because machine was clicking for some time). After the locking was removed on the scale, tension pulled was showing around 52 lbs after clicking for 40-50 secs. So it does pull the tension accurately it would seem. However after I string a racquet and use Tourna Stringmeter to check the approx. tension, I observe that middle 3-4 strings will always show 8-10 lbs lower than desired tension and other strings would have close to desired tension. I actually first found out about this when person I did stringing for had complained that tension feels much lower; when I checked with the stringmeter it was showing more than 10 lbs lower.

All these issues point to your clamps slipping. They could be so dirty it slips even when at the right width for the string, especially since you say you've owned it for 3 years and not serviced them at all. Have you stripped and cleaned the claws with alcohol to get the crud off?
FYI you need to do research on dynamic vs reference tension, and how those tension tools are measuring only dynamic tension. That said, as a few have said, each machine needs to be tailored to the preference of the player. I string 2 lbs higher on the PS than on the Baiardo of my pro shop stringer.

Quite easy. I used a hook top type digital luggage with string tied to the scale hook and just attach the top hook to the mount of the throat mount point, and pull through the top of an old racquet. Those gamma scales are overkill to see if the machine is calibrated, for the home user.

I watched the videos I was sent again and the tensioning issue is happening before the string is clamped off. See the video here "https://player.vimeo.com/video/834630258?h=b7b6480650"

Sorry. I took one last year for the review but realized I needed a host domain. Too lazy to register for IMGUR etc.
Got a photo of this set up?
That's my point. It looks like the clamps are slipping from the previous row, so it's just slowly slipping loose. That's what I see is happening.

True, it is hard to see the overall picture from this video.... maybe TennisShishya can do another video showing a closeup of the clamps while tensioning. He can also put a felt tip pen mark on the string to show if it is slipping through the clamp.
Here is the link to the other video I was sent of a cross being tensioned: https://vimeo.com/834630273?share=copy

@TennisShishya I suggest the easiest approach is to clean the clamps first to see if that's the issue. Usually it's the basic (lack of) maintenance that causes most of the problems. Then test the clamps and tighten based on the test suggested. Then you can eliminate clamps as the issue if it isn't slipping.

It appears to be repulling and holding tension as I do not see string or tension head changing position. If clamp was slipping tension head would advance. Might be worth reaching out and asking if you can send in for testing and/or a repair if needed?

My issue is that it goes on for too long most times especially when stringing mains; happens for relatively short time for crosses.
When you’re tensioning mains you have more energy in the string because it is longer and has fewer friction points than crosses.
It looks like the rotary gripper of the PS2.0 is moving back (counter clockwise) toward the frame after tension is pulled. That should never happen IMO. Once tension is reached, for the tension gripper to move back tension would have to go up, and unless your tugging on the string, that shouldn’t happen. If the claws or gripper were slipping the gripper would turn clockwise to increase tension lost. Clearly a tension module problem. Sorry that’s no help in getting your issue resolved.

So I did clean up the clamps and the gripper with some rubbing alcohol, tightened up the clamps even more so that they left indentations on the string. Clicking still continued. Marked the strings around the clamps to see if it was slipping at all; marks on the strings didn't move at all. Even the strings around the gripper didn't seem to slip. Strings were just moving along with the gripper.

@Irvin

If it is tension module problem, can it be fixed by oneself at home? what parts would I have to replace? I have had multiple discussions with PS team and they had gone back and forth on acknowledging that this is an issue with the machine.

I agree it is a PS tension module problem but I have no idea how to fix it or if you can. It sounds like PS does not want to tell you how to fix it either. I’m not sure if sending it back for repair is an option but that’s what I would suggest.

If you've had additional contact with these folks at PS, I'm still absolutely baffled as to why PS has yet to tell you "albeit the stringing machine is no longer under our own mfg's warranty, if you would like to send the stringer back to us, you will incur shipping out of your own pocket to get it here, and probably return shipping I'm sure, in addition to all parts involved and labor cost"...if you choose this as an option.

Now that you've ruled out dirty clamps as a possible cause, ruled out whether your clamps can tighten enough, ruled out tension head slippage (string slippage in any or all cases)...what's the option(s) left on the table to avoid ending up with a roughly 5lb paperweight?

Don't get me wrong, I want to see your machine working correctly like it's designed, like everyone else in here does. I simply revert back to my quote from my previous post #10... "Eventually buying another machine from a different mfg'r is prob going to be the resolution here".

One has to wonder about the CS at PS if they’re not even willing to repair it at cost (post warranty).

It's doing what it should do, but the constant pull is still adjusting even after tension is achieved. The tension head is advancing slowly. It's very clear that the tensioner is pulling (clockwise) till green light, then it readjusts like constant pull should be doing.

Now that you seem to have eliminated the claws as the issue, I'm still a little confused by your statement that the string jobs have been showing to have lower tension. What tensions and strings are you using?
Re: sending it back to fix.
I understand the units are at least assembled in South Korea. I don't know where you are located.

Personally I think the tech support diagnosed like I did, assuming that it was the clamps, because there is no mechanical fault in terms of the tensioning, based on the videos so far. Now that the OP has eliminated the clamps as an issue, the trouble shooting continues. I assume the tech support were trying save the OP the expense of sending the unit to South Korea, only to find it's not the problem. The new info should help the tech support diagnose the issue further, and hopefully help the OP resolve the issue asap!
Normally I won't engage, but touting a working machine is better or insinuating it was a mistake to purchase a product, when there is a TT member trying to seek help in earnest for their issue, is rather unnecessarily unsympathetic.
That said, product comparisons should be done with nuance and context. If you want an fixed based heavy system, there are plenty of choices to choose from.
The Pro Stringer is a unique product. We've made back the cost of the unit and more with the savings from stringing with on site stringers in the first 8 months of ownership, while traveling on tournaments in planes and car. It's a different product for different users. In fact, I'm thinking of buying a 2nd one for myself to travel with for ITF masters events, after having a few difficulties with onsite stringers with regards to tensions and even tie offs. I don't like the tension needle indicator and am hoping for a digitized version, which isn't really necessary for the core users the product is designed for. However, I'd appreciate it for my presbyopic eyes.

It's doing what it should do, but the constant pull is still adjusting even after tension is achieved. The tension head is advancing slowly. It's very clear that the tensioner is pulling (clockwise) till green light, then it readjusts like constant pull should be doing.



Now that you seem to have eliminated the claws as the issue, I'm still a little confused by your statement that the string jobs have been showing to have lower tension. What tensions and strings are you using?
Re: sending it back to fix.
I understand the units are at least assembled in South Korea. I don't know where you are located.
I string mine with full poly 17g (likes of Black Widow, Tour Bite Soft, Hyper G, Pro Line 2). My desired tension is 50-52 lbs. Immediately after stringing when I check the tension using Tourna Stringmeter, it shows around 40 lbs. I have used this device to check the tension after getting it strung from a tennis shop and it shows close to my desired tension.
I am based in Albany, NY.
My only issue with the tech support was that on a video call with them, I showed them the live demo of my issue and they said immediately yes this is an issue and you will have to send it to Korea (I bear the shipping cost and they will take care of servicing cost). After the call, when I asked about the process for sending it to Korea, another tech support rep again asked me what the issue was and on sharing the videos of my issue, they said the machine is fine and they don't see any issue with it.

Well I suggest you call them again and tell them you've got further info and upgrade the ticket to someone who will have to listen. If 1 tech says yes and another tech says no, then you go to the manager to get a tie breaker. ;)

I am working with PS team. Based on my discussions with them, I have shipped my machine to their warehouse in US (supposed to reach sometime this week) and they will try to fix the issue. In the interim, they said they will send me a replacement machine. Thank you to Pro Stringer team for that !!!
Once I get any details of the issue with the machine I will update the forum.

Thant is great news TennisShishya! ;)
Oh yeah? Are you going to send your PS back to the good ol’ US of A if it starts clicking? LOL Actually I don’t think it’s clicking I think it’s slipping. The clicking is just the PS normal CP operation trying to recover from the slip. It is a sign to me the PS is a constant pull if there was ever any doubt.

Little better outcome than I predicted would happen but Pro Stringer I'm sure is well aware of these comments concerning their Platinum 2.0 machine, especially on the biggest tennis forum out there.

That's good news. I'm happy to hear they did the right thing, albeit with a bit of internet encouragement, especially from other owners.

Hello @TennisShishya
I would contact JC Carpentier at TennisMachines.com. He is one of the best in the country at repairing stringing and ball machines. He will spend time with you on the phone and be honest on what can or should be done as the best course of action. I have used him several times with 100% satisfaction.
Agreed! They’re a fantastic vendor that @Power Player recommended last year.
