- Welcome to part 3 of the video series documenting the build of our new CNC plasma cutting table. In this video, I'll explain the components that went into building the X, Y and Z frame rails.
The ballscrews used are 1500mm SFU1605 (16mm diameter with a pitch of 5mm, so 1 revolution of the ballscrew moves the ball nut 5mm).
The linear rails are 1500mm HGR20 with HGR20CA slider blocks.
The Z axis unit was purchased as a complete unit.
All these items were purchased from eBay.

Thanks again for watching and we'll see you in Part 4.
Wow definitely the best no nonsense explaining it i watched alot videos you're Is best so far than you for the time and part of knowledge you are sharing with us newbies .
Hi Bob, thanks for your kind words. I hope you found my video series helpful if you're building your own table.
Love the video. It gave me confidence to start my own cnc. Most CZcamsrs hold their design like grandma's cake recipe. Thank you brother.
Hey Jonathan, I'm glad you found my videos helpful. Good luck with your build. I got a lot of help from others on CZcams, so I thought it was only fair that I gave something back to others.
Absolutely the best explanation on a diy build!!! Your awesome. I am currently making my own. Your series of videos have given me inspiration again!
Hey Mike, I'm glad you found my videos helpful. Good luck with your build. I look forward to seeing it up and running.
Very well explained Russell. Love the over engineering, it should last forever.
Thanks Jim....I tend to overengineer everything I build.
Thank you so much! I'm halfway through my build and I keep reworking the linear motion. It's getting exhausting, I just want the machine complete! I think I like your way the best. I started out with the rolling bearings technique along 50mm square tubing and some belts but then ditched the roller bearings idea and went with these linear rails and ballscrews. I don't prefer belts cause I built a small langmuir clone to start out and the steel reinforced belts ended up stretching and gave me 7 thou backlash.
I really like the 160mm gantry offset box you are utilizing. I'll be incorporating that into my design I'm sure.
Hey Tyler, thanks for your comments and I'm glad my build videos are helpful to you. I know there are those who don't believe ballscrews should be used for plasma cutting, but I've had no issues so far with my table design. Langmuir use a lead screw on their tables and that's where I got the idea from.
I was considering going with a belt drive system if I ever get around to building a bigger table, but if you've seen the belts stretch, then that's not a good thing..
Feel free to email me (rmhyde58@gmail.com) if you have any questions about my build, or if you need help with any part of your build.
Awesome work, clearly a very well thought out build using good components and executed well ,making good progress mate keep em coming 😀👍
Thanks Clint. I'm currently putting it all together. I've made the support table and the Y axes cross-members...but you'll have to wait for the release of Part 4 to see it!!!
Hi, Nice!
But think about change screw drive to other drive ( belts or pinion/rack ) in this nice machine!
You're doing a great job with these movies. I am not a mechanic, but I can write something from the observation of many machines.
Screw is good for milling etc, not for plasma or laser CNC machines. This your axis isn't to long and maybe will working good but for long axis scraw working like guitar string and have big resonance for specis speeds and depended of axis position (the best result when axis is on midpoint ). Second problem is speed - if you are using stepper motor without any mechanical transmission then dynamics and speed of machine isn't good ( needed very high speed of motor. Motor need time for accelerate and deccelerate to high speed also for not high speed of axis ).
Thick materials slowly will cut perfectly.
Thin materials plasma cutters can cut only if dynamisc is very high, always if slow down cutting quality isn't good. Also maximum speed isn't posible and move long distance need lot of time ( floating without cutting ) don't know in this case but think that for longer axis maximum stable speed will be not too high.
I'm sorry - i don't like to criticize the wonderful machines built but it's important questions and i think that your canal will be very popularity.
I saw lot of different plasma machines and trust me, more better working with belt or pinion/rack.
Standard floating speeds of Plasma machines are 15-25m / min. Thin materials need 4000 - 9000mm /min for good quality of cutting.
Perfect gear ratio is 30-70mm / motor rev, not 5mm / motor rev ;)
Screw is perfect for milling.
Good Luck !!!
Hope that all will working better as i think.
Hi Lukasz, I appreciate your kind words regarding my channel and my table that I'm building. Thanks also for the detailed explanation of the drive system, which I will bear in mind when my table is up and running...hopefully by next week.
Great videos mate. I’m just about to build my machine. Your giving me some great ideas. Cheers Robert
Hi Robert, if you need any help with your table build feel free to email me....rmhyde58@gmail.com
Very nice build looks great
Thanks Randy. Part 4 of the build should be out by early next week. I expect to have the table up and working by next weekend....fingers crossed!
Hey rusty, good job mate.
Ive watched all your vids a couple times now but because im looking at a million other things cnc related, so you probably mentioned it.
But did you source your rails and bearings local or?
Go to china?
Im just about to start but because things weren't difficult enough i decided to buy a Mill and CNC that while im at it ahahahahaha
I bought my linear rails and ballscrews off eBay, along with a lot of other parts for my table build. The other option would be somewhere like AliExpress, which is based in China.
Hi
Do you have a link for the z axe assembly?
Thanks
I like your videos, very helpfull.
Hi Blou, I ordered the Z axis unit off eBay. If you use this search term, you be able to find the unit I bought, or something similar....'Nema23 Stepper Motor 100mm Linear Motion 1605 Ball Screw Guide Rail Slide Table'
I hope this helps.
perfect 👍 thanks
Thanks Mike, I'm glad you're enjoying the videos. Part 5 will be released tonight so keep an eye out for it.
how many hours on the table now? any things you would change?
The table is now 2 1/2 years old and while not used every day, has seen quite a few sheets of metal pass over it. As for things I'd change, maybe the ballscrews from 1605 to 2010, just to make it run a bit faster when cutting thin material, but turning the amps down on the plasma cutter and tweaking the cut speed have given me good results, though. If I built a full size table, I'd go with rack & pinion drive system.
Hi Rusty. Hope you are doing well. Just a question about your linear rails and bearings. Did you have any issues with getting the bearings to move smoothly along the rails? I bought the same rails and mine are not nearly as smooth as it appears that yours are. Thanks!
Hi Kerry. I didn't have any issues with my linear bearings on the rails...they moved nice and smoothly. Are yours notchy in places or all along the rail??
@@RustysMetalCutSignsDesigns They are a bit notchy in places. I am gonna give them a good cleaning and see if it makes them better. Seems funny that all the rails and bearings would feel the same way.
Make sure you don't lose any of the balls out of the bearing housing, ok.
@@RustysMetalCutSignsDesigns Guess I am gonna do something different for rails. I cleaned the rails and bearings. Two of the bearings were missing balls out of the box so I added balls. Frustrating……
what say that tube is straight?
If you're referring to the box section I used to make the frame rails, I visually inspected all the steel I used for the build, to ensure it wasn't damaged.
@@RustysOutbackAdventures point being there is a straight tube in the world. that rail is most likely much straighter than the tube. and your deflecting the rail to match the tube. just sayin.
This video is sort of having a 250,000-dollar garage shop and spending 20,000 dollars on parts to put it together like Lego. How can I duplicate this without having the bells and whistles?
I'm not sure there are too many 'bells and whistles' on my table....it's a fairly basic design that works well for me. Are you thinking of building your own table??
Actually use lego if you want cheaper. Only need a spanner , drill and welder as its the most cost effective design . If you don't have these tools you won't be building anything as super won't hold the parts together sadly
