But how will the timing sync? I think there’s tech needed too… OR (and I still haven’t gotten around to this) I’ve been thinking about 2 on 1 drills with the ball machine. Have ball machine start first 4 balls… but then human player takes over waiting for that dtl shot to start the second half of the point.
Only 'sync' I can think of in running two machines, whether similar or different, is simply stagger the ball launch times/shot interval times. Then when you factor in different height/trajectory/types of shots and the time those lobs, etc take before the next ball is launched from the other machine, you'd be run ragged in no time. Could you imagine the connectivity issues running two Proton machines?...seems like brother Jonah is still playing hell keeping one connected within a pretty minimum distance. Like I mentioned in a post several back, some should've just bought a human. ;)

If you are super adamant about it, could just build your own custom routines and play with the delays so they space out correctly. Not easy but this really seems to be a fantasy of yours lol.

Not that hard to sync if a physical connection is used, a 30-40' cable would take care of it. But, you're right, just hire someone or find a free hitting partner.

Some clever ideas here... :).


I still think that getting the timing without some sort of communication line between two machines is asking for a lot of wasted energy and money.

Also... love USMC-615's point about just finding a human! On my end, my schedule is packed so I lost the ability to be flexible on time/location to play tennis. Basically, it's not always possible to find a human. This problem gets even harder when the human you're looking for should be a solid 4.5 ntrp minimum level (at least on certain strokes). Proton as-is has been so good that if i go too long without a robot I actually carve out a session or without a human partner just to work on some aspects of my game. Even getting a tennis pro isn't that easy of a solution since you have to schedule and find the right person. Probably super different for other people in the more beginner to intermediate range where it's so much easier to find other players at your level, in your area, at certain times.
 
Update on my drifting issue: Asked an engineer friend to open up my proton and adjust the belt based on helpful info I got from Jonah. Jury is still out as to whether the fix holds up over time, but the belt will likely need to be adjusted again at some point. I didn't trust myself to do it myself so therefore my request for help from someone who knows more than I do (my frustrating superpower is that if I look at electronics or other technology, it breaks in ways that few pople can figure out). My friend's take on the whole drifting issue is that the ultimate fix needs to be a software fix, and that it is just the nature of the methanicals that they will get out of whack occasionally; no way around that.

I just sent mine to the shop. Drifted in the beginning but belt got so bad no matter how much I adjusted it didn't help. They said they fixed it and are sending it back with extended warranty now.

So some frustration but their customer service has been very pleasant. I hope the fix helps.

Starting to have to calibrate after every basket. Also encountering balls not feeding into the shooter more often - The peg rotates but isn't enough to loosen balls in the hopper enough to drop it into the rotating slot for firing.

Also have a couple of side to side custom programs I've made, but finding that it shoots more towards the middle for 1 side and too far on the other side, further indicating there's drifting or calibration issues.

User experience is definitely dropping.

Join the club. Sound a lot like my issue. The belt as slipping and progressively got worse and worse. I just got mine back from the shop. I haven't used it yet but I can tell it doesn't take much to slip the belt still.

Might have to send it back again...

I assume you emailed their support to initiate the process? Looks like I'll need to do that.

Yea I emailed them my situation. Pretty responsive and nice people. They emailed me a shipping label, had to use my old box so hope you didn't throw that out. It looks like they replaced my machine completely or they did one hell of a job cleaning it with the one I got back and gave me an extended warranty. So their customer service is awesome, I'll give them that. But little worried with the issue still not being fixed after all that hassle.

I beg to differ with your engineer friend. It is not the nature of mechanicals to get out of whack unless they are improperly designed. My Spinfire has zero drift and son and I have been using it a few times a week since 2014. We also have a Proton from the first sale and it drifts because it was designed to so that it does. Allow me to explain: The machine rests only on 3 small points, 2 at the back and 1 at the front. The 2 at the back are smooth wheels of which only about 3/16" of an each touch the ground which for a very light machine does not provide much friction to resist kick back at all when a ball is shot. The front pin that rests on the small disc which by design moves forward and back when the machine moves vertically. It does so horizontally forwards and backwards to a maximum of 1.5" at the max vertical machine elevation.

Drift backwards or to the side cannot be corrected by firmware (aka software built into the MCU). To do that the Proton would require a method of measuring the initial X & Y horizontal home positions of the machine on the court surface wwhen it is first set up and shooting balls down the centerline properly, ie without drift having happened. Drift left and right creates a bigger issue than forward or backward as it really screws up the drills. To correct that the drift the machine would then have to self-correct it. That is one whole lot of additional parts, firmware and complexity which would add a lot of cost. It won't happen. Adding weight could help but then the machine's horizontal and vertical motors were designed for a 19 lb machine not one that is a lot heavier, not to mention it would affect the forward and backward movement of the front pin the raises and lowers the machine.

Proton states on their website under Troubleshooting that 'Some drift is natural, and you should just re-aim the machine'. Drift is not natural. We had a Lobster Grand IV before the Spinfire and it didn't drift either. The drift is a result of inadequate mechanical design. If you are not getting drift with the Proton then you are likely not shooting many balls left and right much but more forward or in the same direction. The Proton drifts by design as many have reported on here.

I'd agree with everything said right here, and I've yet to even see a Proton machine in person. But I spent a crazy amount of time researching and reading on the Proton. Call it just good ol' fashioned intuition and common sense, but this perpetual problem of drifting is exactly why I ruled the Proton out in the first round of the three machines I settled on to purchase. Then the Lobster Elite Grand Four got the boot (lack of internal/hidden oscillation), and that left the clear winner...the Spinfire Pro2 V2 I bought.

And I'm not making this comment in the least trying to bust Proton owners' balls one bit...I really wanted to like the Proton for its' ease, portability, and ball capacity for such a small footprint. But there is no software/firmware fix for this 'physical' problem of drifting. The drifting is a physical 'hardware' issue, how the machine is physically built.

I have a Proton machine that I've used this summer to help teach my two young teenagers. It's done a great job. I like the machine much better than the Lobster Grand IV and Prince ball machines that I've owned. The small size is a plus, but the programmability is the key to the machine. It is so flexible and responsive to the smartphone interface and with creating custom drills. The single ball fire is great for coaching.

I have never encountered the drift to be more than a minor occurance. The small size and shape of the machine means that I've had more issue with trying to line it up properly than having it drift on me.
Prior to getting the Proton I had planned to get a piece of anti-slip material (made for woodworking) due to reports in this thread, but didn't need to based on my results. The drills we use the most have a lot of side to side motion. The courts we play on do have a lot of grip so drifting might depend on the condition of the court.

When they say drifting is natural, obviously it means it's natural on the Proton machine ... and not something that affects other machines. They are not claiming it's an unsolvable problem in the tennis ball machine industry. It's definitely a design shortfall related to their product.

It's probably the tradeoff between having something light and portable. Granted I have 0 experience w/ any other machine, I'm assuming the drifting occurs because as the balls empty from the machine, there's just not enough weight to withstand the recoil from firing a ball and thus causing it to lose its calibration.

Got an order in for October delivery yesterday. October allotment opened for ordering at 8 am PDT; sold out October allotment by 8:08 am PDT.
 
Mine is still drifting a bit despite adjusting the belt. When running the sequences; engaging the Random setting helps with that some. While I may end up sending it back to be worked on, I still wholheartedly support the machine and would buy it again.

From the videos it seems to move even with a full basket. Is it more likely because it's a tripod design vs 4 post feet design most ball machines use?

Possibly? My guess is that the weight of ~100 balls + the machine is what they felt was acceptable for recoil while also keeping the motor happy and not overworking it. I assume if you increase the weight of the actual machine so that it can have a higher static weight w/out any dependency on balls, then the machine will stay put more often. But at that point, the extra weight will likely impact the machine's ability to move and shoot side to side. Even if it remains capable, that's still extra stress on the motor to move a higher weight that could result in premature failure.

All just me spitballing ideas off the top of my head. Take w/ a grain of salt.

sending my proton with the non-functioning vertical riser back to Jonah today. They issued me a UPS label, I am reusing the box they used to ship the Proton, and hopefully my repaired Proton will be as good as new soon.

They were pretty good when I sent mine in. It seems like they just sent me a brand new machine back. But has been working pretty well since thankfully and threw in an extended warranty on top of that. So good customer service imo. Was about a 2 week turn around for me.

Overall I would rate Proton positively and recommend the machine for those looking for a compact ball machine. But would reconsider if you want a no-nonsense machine.

Ordered in May for July delivery. Almost the end of August and nothing...

That’s not good. I have one ordered for August delivery and have not heard anything either and haven’t received the fulfillment email. For those who have received their Protons, did you get it the month you were supposed to or was it delayed?

Just an update, I reached out to them and they sent me confirmation to make payment. Machine came pretty much overnight and having hit with it a couple times now I can safely say I am in love with it. I’m mindful that it may start to have mechanical issues down the road but so far it is everything I ever wanted in a ball machine.

Does anyone have both a lobster grand or elite and a proton. At max speed is the proton faster? I’ve easily replaced the throw wheels on the lobster, is the proton easy to work with?
 
Received my proton yesterday and was able to get out today and put it thru an hour of work. Using it on clay courts as that is what our club has. It performed excellent! Far exceeding my expectation. I was a little nervous going in because I have read a few things on this thread that were of concern but it performed excellent! Weight is great, app (android in my case) worked perfectly, battery (which you can get a ryobi 18v as a replacement or spare didn’t go down at all after an hour of 55mph and high spin hitting. Please with it at The moment, time will tell.

I received the proton and put it to the test for about two hours yesterday 9/7. I also had slight concerns after reading some of these posts but not am glad to report that this machine is well worth the money. I had no issues with app recognition across the court and further(10 yards back) , no issues with balls jamming, and no noticeable drift issues. You can only adjust the height of the balls from the machine from what I can tell which is perfectly fine to me. I did a lot of testing with topspin, height, and speed which was a lot of fun!! I was pouring sweat within 5 minutes so prepare to get worked. I got an extra battery but doubt I'll ever need to use it because at max settings the machine was still going strong 2 hours in. I'm glad I bought this machine over any other machine for multiple reasons...it has everything you want in one rather than 1-2 out of 6 features for the same price range. For those of you complaining about the drift stop being babies and adjust your machine after you clear the hopper :-D.

the drift is annoying. The drift shouldn’t be there. But having stayed updated with this thread…. You’d really think it was some monumental issue. It’s not.

for those new buyers I’d recommend you keep your box somewhere. It’s like $50 bucks for UPS to package it for you. If you ever need a warranty claim, that’s on you. Other than that the warranty experience (ime) is quite smooth and painless.

For sure, this machine has saved me thousands of dollars already on money I'd have paid to someone to hit or feed balls at a high enough level for my son. He still does lessons and clinics, but sometimes he just needs reps when he's working on grooving something specific.

similarly for me; I can now go ahead and book a court for myself the times I can get out. And then if I can’t get a human on the other side of the court, this ball machine is an incredible backup.

so good in fact that every now and then I don’t want a human and instead want to work on something specific with the machine. Programming patterns is huge. My approach shot transitioning off a baseline ground stroke has never been better.

Been looking into machines for about a week and just ran into the Proton last night. I WAS between a Spinfire and a Silent Partner (max speed is very enticing), but now… I have some questions! I find the Hydrogen Sports website a little lacking on information, and haven’t found anything anywhere about shot time intervals. I’m assuming this is adjustable, but can someone with one confirm? Thanks!

shot delay can be programmed from 2sec to 10sec intervals.

Yep. Got to reuse my box that it was shipped in. They fixed it in two weeks. They shipped it back last week and I’ll be back in town tomorrow.

My machine works as advertised ... few friends tried and loved it !

Minor issues are annoying but tolerable, tech changes fast and Hydrogen is not far behind (still behind ...) , sometimes they are ahead of users ... price is creeping up and I am happy with my purchase (bought additional warranty).

Between playing matches, hitting with friends and family and having paid team coaching sessions, I can really see good use of extra 6000 fine tuned shots/year !

16 american dollar cents a shot !? Go to cheapest local high school tennis kid (good tennis program school) to feed you backhand balls at certain RPM at certain interval at certain speed ... good luck, $60-80/hr. here where I live and you get 300-400 shots max ... how many american dollars is that ?

Well under warranty, right ?

Portability and programmability and price ... pick your flavor !

I’ve got two lobster elites and the proton. The proton is about the same speed but spins faster. Its not really anything noticeable unless you’re focusing on it. While practicing, the lobster is every bit as competent as the proton.

As far as people opting out of the proton - this thread has become increasingly nit picking due to skeptical or apprehensive potential buyers trying to get every last possible negative out of us. Like another commenter said - this thread is greatly exaggerated compared to what you really experience in practice.

At this point, you gotta just man up and roll the dice with the (gasp!) $160 restocking fee in the very rare event you just can’t handle the cons.

For me, I don’t notice the drift at all, but the more I read this thread, maybe I will start noticing drift. Maybe when I go back to reload the proton next time I practice, I will focus on the few inches it drifted and curse it loudly for such terrible engineering. Maybe I’ll even let it ruin my fun for the day.

Or maybe I’ll just reload it up, program my drills on my phone (that is 100% going to disconnect like it always does) and then have some fun hitting some balls despite those inconveniences. Because the proton DOES do that right. It will place the balls damn near perfect for the entire basket. You really will be amazed at how badass this little thing is when you use it.

It boils down to priorities and trade offs. For me, adjusting a couple inches of drift and not being able to modify shots from the baseline is the trade-off I’m more than happy to make for the ability to only have ONE trip from the car with all my gear - and do so without the slightest straining.

These are all good machines - it’s up to you what features are most important.

My Proton kicks my ass. I love the Rally Approach Volley built in drill. And it has decent variation unlike the relatively more fixed Spinfire.

So looks like deposit goes in 2 months ahead of time, but may get an earlier delivery. I'm stalking the site for when I can put a deposit down for the earliest available spot
