I know what you mean pal..i accumulated the parts over time.. jumping on deals etc as i find them.Something I've always wanted but can't justify the outlay
Same here to be totally honest.Something I've always wanted but can't justify the outlay
You are right..i did know that rack pinion was the better method,i see so many small builds running screws and think i would be happy with those cuts...that performance etc.just my two cents worth.
Why ball screw for the drive?
Depending on the plasma power and the sheet thickness, speed is an important factor to get good cuts. Getting speed on ball screws you can get whip once the rpm gets up. Rack and pinion is the much better method, just saying. Anyway that is my view, good building
Nothing daft about it, they seem to work well by all accounts i just didn't consider themDaft question (maybe) why not belt drive?
The one think that might possibly go against belt is sparks might cause issues.Daft question (maybe) why not belt drive?
Sparks aren't any more of a problem for belts, than general plasma dust is for any transmissions system.The one think that might possibly go against belt is sparks might cause issues.
That's pure speculation by the way.
You should have seen @MattH place before he closed down. wow...mega talented.I'm in awe of people who've built these CNC tables. I mean I know the theory but how to size what size rack, pinion, motor etc I haven't a clue.
Videos, videos and then some more videos followed by Dr Google some more Utube then some manufactured table info. I think you get the drift. From memory I looked around for about 6 months and there was a Gbyt or two consumed in the process, but I got wiser. It was a painfully slow process at first, but it got better. 'You just don't know what you don't know' Ignorance is your worst enemy with these things. There is so much to know and understand for one of these things to work. To work I mean work properly, not just sometimes, but each and every time it is required, to complete each and every job it is set and also to be able to easily recover from mishaps. I am just a bit wiser now and understand what goes into one and some of the dynamics involved. Does mine work, well yes, could it be better, hell yes, do I want to improve it, a little. There is no demand at the moment, the machine is idle, so there is no need, other work at the moment, once that clears I will have a go. Once you have built one you learn as much from your failures as you do from your successes, you will never know if you don't have a go!I'm sure. Doesn't help me build one though!
He might do if you asked him. He's retired to gods country now.I'm sure. Doesn't help me build one though!
He's retired to gods country now.
Big mill was sold.He might do if you asked him. He's retired to gods country now.
Which reminds me what happened to your mega mill and the even more impressive self build one you was building @MattH
