They can be useful. It all depends on what materials you want to cut with them, which you've not specified... If, for example, you just want to...

You can get 12mm (RM1204) ballscrews from linearmotionbearings2008 on eBay. The steel the ballnuts is made from is just about soft enough to mill, so...

You could go down to 12mm dia ball screw. The biggest problem will be finding enough room for the ball nut! On my Sieg X1 conversion I used RSW...

Many thanks i2i. Yes commonsense must prevail, i am converting to CNC for greater control and accuracy, so i will go down the ball screw route, if...

Hello Lasek: You should direct your question to "Lovelearn". He might help you with this problem. I know that you have to specifically purchase the...

Especially if you're welding stuff :D I remember welding in a pair of trainers a long time ago, one of those 'it will only take a second to weld'...

That's quite artistic that is..... But when I eventually get to machine stuff, I must remember to not wear my usual cheap flip-flops...

Not sure if you have looked at buying your ballscrews from China? There is a massive cost difference between China and the UK. Check out...

Unless I'm out of touch with other couplings, not that I'd use them, I thought they were about the same price. I get mine from ARC, used to buy off...

Hi John I agree, i have used Oldham couplings for many years, i just thought things may have moved on a little, they seem so expensive these days....

Hello, I have bought 5 axis break board and 3 axis dispaly module. Unfortunatly cable this display is not comapatibile with this board because...

Have you tried the local builders yards? Sure they must get full sheets that get broken & might sell you a bit.

You can normally find this kind of thing around B&Q in the insulation section, if there is a broken sheet ask if you can have it for a discount :D

so thats basically just a generic chinese cnc with an eco-cam knife bolted to an mdf plate? whats the european control, usb-cnc? Hold down system...

at the end of the day, you're going to cnc a manual mill for what reason. You want an accurate computer controlled milling machine that will cut...

Agreed, this can be a problem but like everything it depends on the design. Some use springs to compress the split nut and of course these flex under...

Iwant1, it has sucked up a big percentage of my spare time this year, but as my ball and chain cleared off a few years ago :glee: telling everyone to...

Dave, last week when you posted pictures of your build, and thought what a neat build, hang on, that looks like mine. Well done for getting so far....

Having nearly finished a build similar to what your describing (mine having a cutting area of 1200X700X200) Welded box section steel frame (50x50x3)...

The new power circuit is now in, A used vacuum pump purchased and the machine is connected up. next job is to "plumb in" the vacuum and compressed...

:whistle::whistle: Delrin will have reduced friction But I found that it just acted as a damper and masked the backlash. measuring low...

Clearly, yes some people have strong opinions. Personally I think it depends on what you intend to use the machins for. I am using Delrin anti...

Ditto on using heavy sections, I bought a job lot cheap on ebay a year or two ago and it was a mix of light and heavy, the light is much weaker and...

Hi Pilot Tom Hope you are getting on well with your design. I have worked up the final drawings and going with Jazz's approach on the use of 80x40...
