Which cnc

[Jonathan]

Now throw in all the mounting hardware, driver, building up etc and that £250 is no where near.

I did say very roughly. From eBay a 1500mm ballscrew with the bearing mounts is £115 but he's using a rotating nut so the bearings will be more expensive - call it £160. One additional 3Nm motor and 80V driver is £75 max. Better PSU needed, another £15 to supply the extra motor. Another two pulleys and a belt, £15. That's 160+75+15+15=£265 so I think very roughly £250 was a reasonable statement as clearly I wasn't including labour.

Presumably Jonathon you are paying business rates on that 100' x 80' shed in your back garden just as you are reporting everything you earn to the revenue ?

I might not pay revenue but I do pay VAT.

It's a no win situation, buy Chinese and it's crap no matter what level you buy at, buy British and you are getting ripped off and attacked by the garden shed brigade wanting to buy everything for nothing but sell their product at high prices.

Who said anything about charging a high price? Imo the prices charged in the CNC industry are usually extortionate. I try to lead by example by charging around £6-£7 per hour for time. My objective is education, interest and not making a loss, not looking after other people's profits.

Why not ask them how much to add a second ballscrew? They might say it's too much work to change the design, but it can't hurt to ask.

Also in the listing there is far less information than there should be. It doesn't look like any of the pictures have the actual machine that listing is selling - the AR1200. Some of the bigger ones have vacumm bed and other nice things, you can bet that costs more.
