- I Broke My Onefinity Journeyman CNC
Fixing a seized Y-Axis gantry block ball nut. It looks like some regular maintenance is going to be required on the ball screws of my CNC. Thankfully this is a very easy fix, but I sure did learn my lesson to keep things much cleaner in the future. I still believe that this is the best desktop cnc on the market!

Thanks for watching! - Jak na to + styl
part of the problem with this setup (and most hobby cnc) is the exposed screw. it really needs a cover like an accordion over it to keep it clean. and while wd40 is a great lube it is also a great collector of dust.
Sounds like main reason this happened, was, as you said, trying to film the cut, not using dust boot. It is good shop practice with machines to not use compressed air for cleaning chips as it blows the chips inside. Use a shop vac and a good chip / paint, brush to knock them loose.
I've had my Onefinity Journeyman for a week or two, and this happened to me two days ago, luckily I remember watching this video before I bought it so I had an idea of what to do. Thanks!
Very nice detailed video! I happened to find it on the Onefinity forum in the new post sections. You have a great attitude towards this, especially at the end when you said "...worried for nothing...". Man ain't that the truth every day! Good job and keep it up!!
Thanks so much!
Good thing to do after that too to make sure that both Y axis Gantry blocks are symmetric is to make it reach the endpoint towards you and make them both skip steps after hitting the frame. I believe that ensures the symmetry on both Y axis block position! Correct me if i am wrong but i am doing this once in a while on my Ratrig Killerbee.
SOOOO appreciate this video!. I have the same machine and just experienced something similar after a very dusty MDF job
Thank you for sharing a good lesson for novice and experienced users.
You should re oil it 3in1 it is the recommended oil not WD it will rinse the three-in-one out of the bearings and then dry up
Great advice, I've got some on the way! Thanks!
@@HamiltonDilbeck was about to say the same thing, someone came to my workplace and suggested that we should use wd40 for oiling our brand new sawmill. would have seized it up in no time and i was the only one who can read english. there is a big sticker on the machine stating to use thin oil or diesel. wd has lubricating properties but its not oil, for CNC its better to use silicon oil/grease because it wont attract dust.
Yea I was gonna say it to
Wd40 is more of a cleaner than a lubricator
Use the 3in1
WD stands for Water displacement. It’s not an oil. But good for cleaning.
the reason for that is the presure air you use to clean it blows the chips and dust in the mechanik :)
Exactly, all machinists KNOW, to NOT clean machines with compressed air, for THAT reason, blows chips inside everything. Learn to use a chip brush with a vacuum.
Extremely helpful! Thank you!!
Cable tie some sponge either side of the ball nuts and soak it in oil. You will never have a problem again. But use proper oil or grease for the ball nuts, WD40 is only good for cleaning.
Beautiful simple and solid machine, love it.
Great tips!
"oh god no, that did not move at all"
lol
Great video thanks, I would love to get one of these when I get some spare money, well a lot of spare money,, fingers crossed.
I use fans in addition to my dust collection ..... dust / shavings what ever ... is alot easier to keep moving than to pick up ... a little ryobi clip fan and you keep your rails clean during operation ..
Good to khow for the future. Thanks
Thanks for watching!
yeah... certainly the storm in a teacup, but... what I have noticed is the "high quality nicely wobbling" ball crew!
I hoped I was only one lucky with "high quality nicely wobbling" one, feels its a standard in Onefinity !
You should check into static field generators and how they can be used for dust collection like yours. IVI Metal Fab does this type of work, but on an industrial scale. Probably not anything you would want to buy but, If you check out their products it could give you some ideas.
Glad it wasn't broken brother, I probably should clean mine out too, I'm like you, I never clean things haha. however at least now I know if I have an issue like this I can fix it.
Thanks! Yeah, I can get real lazy, but now I know what it leads to!
Thanks for letting me learn from your mistakes. My machine is comming next week.
Use a dry lube on all of the ball screws, like CRC 3084. But clean it all out this time. You left quite a bit of foam particles when you put it back together. A little more time cleaning now, will save you ALOT of time later, doing it again.
Wow, aren't you supposed to lubricate that ball screw with the appropriate grease (that screw you took off should be a greasing nipple it from the looks of it)? If all it gets is some WD40 that thing will run dry and wear out fast it seems like. Probably a good thing to add some extra wipers or covers to stop dust if you do foam like this a lot. Even with a vacuum running.
WD-40 isn't really a long lasting lubricant. It is okay to free up rusted parts for very short term, but I would suggest sewing machine oil or silicone spray as a lubricant.
Thinking that you would probably want to use a dry lubricant on that Y axis assembly when you cleaned it to prevent it from grabbing every piece of dust and dirt known to man. but at least you know how to fix it now.
Glad you figured it out. Frustrating, but an easy fix after discovering it. When mine goes off on it’s own, it seems to be a g code misreading. Usually resetting the program fixes it, but that comes after it’s ruined the workpiece.
That has happened to me once before when I was blowing off the machine mid carve. When the compressed air hit the connection port for a wire it seemed to make it skip over some code. That's the only time for me, though. And yeah the foam was like $20 which is annoying- good thing Amazon has two day delivery!
NICE! Had my heart rate up on the third attempt
Lol me too!
Anytime something like this happens again, CALL THE TECHNICIAN!!! I worked for a company as a production specialist and any time there is an issue, the best person to call for a quick fix is the manufacturer and they will help you for free! Every time. Wonderful people who care.
Thanks for the heads up and thanks for watching!
You had me worried. I just ordered the Journeyman X-50 this week.
Congrats! You're going to love it. It just needs to be maintained every now and then! (Or just good dust collection)
Great vid man glad it's fixed. Was waiting to see what it was myself. Still looking at which machine to get
Which ones are you considering?
@@HamiltonDilbeck cnc4newbie new carve, this or shapeoko pro
@@bryanharness1122 Go for the onefinity! I am a newbie and I beat the crap out of mine making mistakes all the time and it just keeps going. Also the community is awesome. I have had actual facetime convos with a few mods on the facebook group who helped me through multiple issues and are always there when I have a question.
@@A2ZGeek that's great to hear. Cnc4newbie guy FaceTime me other night discussing all their options. I've got a couple months to decide so I've decided 1f or the Cnc4newbie design. They both seem legit and well made. Appreciate your response and advice. Hope to be slinging chips soon. Have good one man
Doctor Ham is in the building.
Always on call
that's a major flaw in design... there should be some protection mechanism sweeping the axle as it goes... Did the equipment stop running automatically... or were you lucky and were attending it!?
UPDATE: I forgot to mention, this is a good video, especially for noobs like me who are making a list of just these sorts of things to place on my maintenance instructions. ...but you need to correct a few things yourself, WD40 !?!? not good, air compressor spewing water!?!? not good, best for cleaning is the spray used for electronic circuits. complete NEW special grease should be applied to the bearings after cleaning them spic and span. Thank you for posting this!
Great video.
Thanks!
Thanks for the video! I'm currently in the same boat with my Onefinity. My issue at the moment is that Onefinity support told me to take the X rail off first. Once I take the two screws out and try to slide the gantry off of the ball nut, it doesn't happen. The gantry and ball nut stay together. It looks easy in your video and Onefinity video. Any suggestions?
I had exactly the same problems as you and had to rebuild my machine 3 times before it would work correctly. Your cutting pattern went offline because stepper motors keep counting when the bearings jam because the is a clutch in the stepper motors that allow it to slip instead of break thereby moving the origin by the amount of slip. For a final fix, I had to go to expensive Super Smart THK bearings with automatic oilers which act as wipers keeping the bearings clean and oiled the problem is totally eliminated. My machine (not Onefinity) runs at a much tighter tolerance (.0002 inches), so is much more prone to jamming than yours. You have to clean and oil after every use to avoid future problems Unless you make the same modifications. Once the machine does this once it will be prone to doing it again. Every time the machine jams you must reset your origin or you destroy your part (in my case three months' work (OUCH !%*$>) . I still think your Onefinity is a very good buy for the price. An ounce of prevention (lubrication) is worth a pound of cure (damaged part, bearing replacement) OUCH.
Hey! Does it get dirty often? And if the machine is used for metal processing? And do the guides get dirty ?
Hey I know I am late to the party . Love your cnc and the working threw getting it going. I noticed something. Wd40 is bar far maybe the worst thing you can use. I know controversial. They actually make lube designed for ball screws that will help with the dust and the like. I also saw watter coming out of your compressed air. Need to drain the tank.
Great insight, thanks!
Absolutely! Get a filter on that airline!
Water in the airline can be driven through your skin and possibly poison you with contamination or air bubbles without leaving a mark and cause cancer or death, stick with a vacuum.
I have 3 air compressors and all 3 have automatic tank drains on them. The main one, which I use for spraying finish, has the drain, a 3 stage filter system and an air cooler unit between the compressor and the tank. Water = 0.
Hey, your mistake will save me a lot of aggravation when I get my machine. This is why I like CZcams over watching TV. I get to really learn something. Thank you.
Quick question. I just set up my onefinity journeyman but the left y axis ball joint will not move really unless I unscrew the tiny black ball screw on the side of it. seems to not be spinning (pneumatic screw when manually moving it) think this same fix that you just pulled off will do the trick?
As xConundrumx already said, I dont think that WD40 is the right choice for this. In my company we use grease of class NLGI 1 (I've been told for over 20 years ). This is well suited for guides up to medium loads. The lubricating film of wd40 is lost relatively quickly. But you can use it great for cleaning and removing grease residues.
Thats great info, thanks!
OneFinity sells a dust boot that collects from the back, would that help in this case. I beleive they refer to it as PWN
So I wondered about dust collecting in these areas. Some machines seem to cover up the rails/ball screws/etc very well. This one is pretty open. Is there some recommendation to do this step you did after a week or two of use.. of only if it gets stuck?
Yeah I think it really depends on your dust collection. I'm making a video that will go into more detail on what I'm planning on doing in the future to combat it.
Be nice if there was a way to have boots on the machine so all tubing and screw drives are either dusted off or blown or vacuumed off so all parts are cleaner when they go through any part of the machine if you know what I mean, or some super stretchy concertina boots to keep them all covered to prevent dust and junk getting in to the operational areas.
There’s a guy who makes them on Etsy
@@SquidsCareToo If you ever find the link would you share it here, or do you know what he calls them so it is easier to find with a search, thanks for letting me and others know,,
Great video. What program do you use for your designs ? I am trying to use vcarve and it's a little tough . Would you be able to do a video on this ?
I use Carveco Maker+. Tons of great videos out there on how it works. Takes a little getting used to, I'm no master at it. But it's great!
I would first try removing the oil port screw and blowing air thru it. If that didn't work then I would do the full teardown.
WD40 gets dumped on a lot, despite the fact that it often works. What you used it for here, to free up the ball nut, well it just works. People love to hate WD40, but it has its uses. I must agree though, that there are often better choices for lubrication.
WD40 stands for "Water Displacement - Formula 40". It's 50% mineral spirits and is primarily a corrosion prevention product with some cleaning and lubricating properties.
To lubricate the ball nuts, DO NOT use any kind of dry lubricant like Teflon (PTFE) or graphite. Note that some lubricants like Tri-Flow Superior Lubricant are blends that contain PTFE, so beware.
Oil is better for dusty environments and grease for clean environments.
To keep the dust out in the first place maybe a better seal would help. Do an internet search for - disk brush ring seal - they may be an option. Might be able make your own from brush type weather stripping?
Thank for the video!
Get way covers or this will happen constantly. This applies x2 with this unsupported rail design which is exposed on all sides.
SAme thing happened to mine. I was dumb, and for some reason thought I never needed to clean mine out.
The dust boot is a huge difference maker.
and onefinity has really good customer service if you even think tou might want to get a hold of them do it. they are actually really fast.
Yeah they have been right on it whenever I've needed them!
Wd40 always wins!! 🙌🏾
Wd40 is not for oiling. Use proper grease to lubricate ballscrew.
And the majority of the dust is still in the nut damaging it from the inside.
Take it off completely and rebuild it.
WD40 master in this job!
Lol, obviously maintenance isn't my forte
I'll stick with my shapeoko and belt system. ;-)
I've heard great things about it!
Dude just eject WD 40 from your shop, I recently convinced my boss to quit using WD40. Try out Superlube with Syncopen, it has a solvent like WD but leaves behind a good amount of silicone lubricant behind. For my Queenbee bearings I use Superlube dri-film spray, I designed a 3d print I use to pop over the can and nozzle to ride along the lead screw and same for when I apply to the linear rails
Some lithium grease on the shafts is not just a good idea....
man that sucks.
I cringe when compressed air is used to "clean" bearings like this, because it's driving dust further into the assembly rather than away.
I dont understand. You spent 4k on a machine and dont want to spend 100 bucks protecting those rails??
Seems obvious to me that dirt and precision ballscrews/shaft bearings dont mix together. But I guess it's not obvious to everybody...
