great upgrade, I built My Cnc from your inspiration a couple years ago. I let my fine dust get away, the powder coating oven control box caught it. Well now my machine is toast! Be careful folks! The fine dust is explosive. Link to my fire on my channel. Will feature it. For education anniversary of fire coming up!

I have been using this linear rail system for years and they are awesome! My cnc machines are enclosed to reduce noise and eliminate the vacuum pickup at the Z axis. Being enclosed and no pickup at the Z axis means lots and lots of air born particles. These linear bearings have no problem dealing with the dust which was a big worry when I went to enclosed. The rails themselves are pretty much indestructible. And the cost of the rails is very low. If you have to replace one of the linear bearings they are also very low cost. I recommend this rail system to everyone. I noticed when you were measuring for racking you did not have your stepper motors engaged which would have made a big difference. I recommend next you upgrade to roller bearing screws for your machine. The prices have really come down. This will take out pretty much any end play, improve precision, and when you power down the system the axis is locked, which is an issue with stepper belt drives. Thanks for the video! You did a great job on the upgrade.

[@DIYBuilds]

Thanks. When the motors have power racking was never an issue that's why I measured it de-energized

[@gj8721]

You were motivator for me 1 year ago to make own diy cnc router. I am glad to see this (updated) machine again 😊 I am going to make second one with sbr linear rails 👍🏻 (I am from Georgia, not state, Country Georgia

[@dangkolache]

I peeped you cutting these in the bluetti vid, I just wasn't expecting another vid so fast. Nicely done! Nice clean upgrade (other than the bolts who selflessly gave their lives for the greater good)

[@jamesokane1739]

The timing of this video worked really well for me. I finally have space to build something similar. Thank you for doing all the research and compiling of details that you've done.

[@rickmccaskill7888]

I did this to my home built 4x4 ft CNC about 18 months ago. Made a world of a difference. Next add a spindle to replace the router. It was ell worth the cost.

[@DIYBuilds]

I don't use the machine near enough for that.

[@fr3dfixit945]

Thank you very much for sharing such an incredible project! Your explanations are so clear and uncluttered that they should serve as a model for other KZbinrs. I may have a solution to the problem of racking of the gantry. To explore the concept (ignoring for a moment the router) if the two pieces of birch holding the new bearings were replaced by a single plank of birch spanning the width of the gantry, the racking would be eliminated-you’d actually have to distort the plank. To accommodate the router and laser, some compromise to the width or placement of the plank. If there is space at the far end to allow some overhang, affixing the plank more in that direction could allow the retention of some of its width. Or maybe just the space behind the path the router/laser travels would be enough to add rigidity. Just a thought, but it may helpful.

[@WillswoodworkingYEG]

Great success

[@fred_derf]

That's a nice upgrade to one of the coolest DIY builds in existence.

[@JoseSilveira-newhandleforYT]

Great upgrade! I was so impressed by the behavior of the DIN rails, that it's almost sad to see them go 🙂 Happy 2023!!!

[@partytempo]

Brad's got VEVOR fever!

[@jamessmithson4757]

It is nice to hear someone on KZbin pronounce the last letter of the alphabet correctly.

[@designandbuild3953]

Looks like a great upgrade to your already capable machine. Your build had to the most well thought out budget build on youtube - still a favorite for me. Happy new year, se you in 23.

[@theinfernalcraftsman]

I saw those in the battery video but didn't mention it in the comments. I built a Joes 06 cnc back in 2007. I recently disposed of most of it... The better 3/4 was unhappy that I did that but I told her that when I built it the cost of ball screws and linear rails was extremely cost prohibitive. Now those parts are readily available and relatively affordable. Not planning to build another router at the moment but maybe a cnc plasma cutter at some point IF I can find somewhere to put it. Now If I could get two 40' sections and 2 20' sections that stuff would make for an awesome gantry crane in the shop... My shop has exceeded max capacity and needs an addition of say 50K sqft... Looks great overall though the canadian name you give the Z axis and the flipping of X and Y did throw me off. :) When I got my first 3d printer I was introduced to a community that flips X and Y as well which still confuses me even today...

[@JeffreyMoon1974]

Nice upgrade! Obviously, you did a great job building the machine to allow for future upgrades because installation seemed pretty straightforward. Have a Happy New Year! 🥳

[@Poolboy28560]

nice, I like it, built my own wood CNC with v bearings as well and will be updating to linear bearings soon. I do need to add "1/2 plus a 16th plus a 32" That would be 19/32 for the record. Sorry its kind of like Sheldon needing to knock three times. ya know ya know

[@PiefacePete46]

That's great, thanks Brad... As others have already said, that should be a really noticeable improvement to what already worked good. I thought you were in for more of a hassle than that! Looking forward to whatever comes next!

[@WillysGarageNorway]

Nice upgrade :) You´re going to notice a big difference from the DIN rails I recon. Happy new year!!

[@DIYBuilds]

Thanks willy you too

[@PiazzaWoodWorks]

Now that’s a nice upgrade

[@davidskolly9291]

Hi Brad, You were right I did enjoy this video. A nice upgrade. I installed similar rails on mine but mounted then on the side.. With mine when the Y axis motors on no racking (some racking when off). I look forward to seeing some CNC action from you.. Happy New Year

[@rickpalechuk4411]

Nice upgrade Brad, Vevor has a lot of great stuff on their website. Thanks for sharing, Cheers

[@thomasmcgravie6932]

Great video of the upgrade... forward thinking the install and dissassembly and explaining your thought process makes a huge difference and so helpful... well done, Happy New Year!

[@colinfarrowdesigns4627]

Good on you brad .Happy holidays

[@Sportsvee]

Can you check for flex again after changing the Y axis. Hoping the rails will help reduce even more. Otherwise, outstanding work as always 👍

[@Poolboy28560]

You want to get rid of more of that racking? Next upgrade! Ball or even Lead Screws!

[@mariushegli]

I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.

[@MtnBike60532]

Nice! I would be interested to see functional results. Do you have anything laying around which pushed the limits of the old rail system which you could recut using the new system, and compare results? I think that would make for a very interesting video

[@leonardino3184]

Sehr gute Arbeit!!! Gruss aus Deutschland

[@MCsCreations]

Fantastic upgrade, dude! It looks much better now! 😃 I bet the X axis made it even sturdier! Stay safe there with your family! 🖖😊 And happy holidays!!!

[@shannonp4037]

Good point. I never considered that the gantry receiving the new rails would minimize the flex as well. Their much stiffer than the DIN rails.Could possible add 2 more on the back side for support only. Or maybe just triangular brackets all around the gantry.

[@MCsCreations]

@@shannonp4037 That would be a very good idea indeed!

[@sportsman1824]

I would interested to hear from you how much the accuracy increased with the new linear bearing. Nice upgrade...

[@patrickmartin3263]

You do awesome work. Will you update the plans?

[@DIYBuilds]

No.

[@wernerschellekens2913]

Very nice job. With the rails on the X asses. Dus that take out more play as they might make the top part of your CNC stronger

[@carpentersson2884]

You should retest the amount of play you have on the x axis. With the new rails on the Y axis, it might have stiffened up the gantry significantly.

[@DIYBuilds]

No it wasn't flex of the beam it was where the beam connects to the uprights.

[@onjofilms]

I think if I were to do it (and I am shortly) I would put a target on the linear bearing, and a laser on one end and align to the laser down the rail.

[@mitziseyfferdt3866]

Awesome 🤩

[@brianmiglionico5835]

Good Day! Do you by any chance have new updated plans, with new links for parts? Some of old links didn't work or the supplies are not available example Cnc 4 axis kit...? And I guess since there are several upgrades made thus new parts 🤷🏼‍♂️. Please let me know thanks.

[@MadAsKiwi]

Nice upgrades. That will definitely take you a long way into the future. I do have a question though, , what was the deflection like after putting the linear rails on the gantry? There was a definite improvement after installing them on the bottom, but the rails should have given some more rigidity to the gantry. Keep up the great content.

[@chris431]

X and z look upgraded, may want to rethink the y axis

[@DIYBuilds]

Huh?

[@FearsomeWarrior]

Surprised you didn’t size mount the main rails. Not losing enough capacity to matter. Great upgrade.

[@DIYBuilds]

I debated it but ultimately It would mean more mods and extending the gantry.

[@fred_derf]

@@DIYBuilds I was surprised you didn't cut off the bottom of the risers and set it on the board you added to the gantries rather than attaching them to the "end grain" -- but then realized it was so that you didn't have to totally rework the Y axis belts.

[@DIYBuilds]

Yup. This project took a long time to balance what was easiest and best for structure. Hence the corner guessets.

[@gregmize01]

Nice!👍👍👍👍

[@shrimpinpat]

You need ro have your CNC mill itself some new aluminum parts

[@DIYBuilds]

Na it's fine.

[@sapelesteve]

Now that's a fantastic upgrade Brad! Happy New Year to you & your family! 💥💥👍👍

[@kevinwillis6707]

looks to me that the upstands on your gantry is the weak point for racking, building them as a box structure would increase the stiffness i think.

[@rickmccaskill7888]

I love your table saw push stick. Did you make a video making it or is the file available? Thank you for sharing.

[@DIYBuilds]

yup, it's an old one. you can find the template on my website under shop project plans. kzbin.info/www/bejne/eoKkaZh4bLJ3eNk&ab_channel=DIYBuilds

[@curtism7203]

Happy to see your back at it again! do you use auto squaring on your cnc? if you do you wont have to worry about racking much.

[@cornerstoneww]

Linear rails like that be expensive! Was looking for them for a potential automated camera slider using raspberry pi or Arduino... But the cost... Nope!

[@VampireOnline]

Did adding the rails at the top help with the racking?

[@FuquarProductions]

Inch and quarter? What is the equivalent in bananas? OR Canadian in speak?

It'd be nice if someone would gift me four linear rails and eight bearing blocks...lucky you!

Ya really wish they did it 4 years ago ;)

[@MRNBricks]

Yea, dude, but it still doesn’t make tacos.

[@DIYBuilds]

U can't be sure it doesnt

[@balazslakatos9817]

no offence, but there are some design issue, it could be more rigid if you do the statics correctly. otherwise nice project.
