Which cnc

[Jonathan]

So you pay VAT on the £6 -£7 per hour you charge then ?

VAT is a tax levied on goods and services. I pay VAT on the things I buy, which a business may not have to. Surely I do not qualify for VAT because:

'When you must register for VAT:
Your turnover for the previous 12 months has gone over a specific limit - called the 'VAT threshold' (currently £77000)'

Plus it says I don't pay income tax below £2710, so that doesn't apply to me or many of the 'garden shed brigade'.

You are working out of a shed that mummy and daddy are paying all the expenses for and you are trying to tell registered business's how to do their job ?

Please don't jump to conclusions, sadly that is no longer the case.

I try to lead by example by charging around £6-£7 per hour for time.

Fookin ell Jonathan i charge between £35-40 per hr but i suppose my garden shed is abit bigger :-P and i have to charge for the Dreaded VAT.

At the end of the day You get what you pay for regarding quality of jobs done and components/machines bought.

I can sympathise with Jonathan but i feel your pain JohnS ;-)

Yup and for £6.00 you are going to get a blinder, that lad puts his prick in places I wouldn't put my umbrella.

Bovey this machine looks well built . . BUT. . don't be seduced by the sight of all the trimmings it shows in the picture and the description.

It says Vacuum and dust extraction built in but it doesn't actually say comes with Vacuum pumps or dust extraction machine.? . . It does say starts from £4995.
Vacuum pumps can be very expensive and it shows 2 so I would be asking some questions to exactly what you get for 5K.?
I would also want to see the machine in the flesh and if you don't have much experience with CNC machines then suggest you take someone with you who does.? It very easy to blind newbies with science and bull shit and unfortunatly lots of company's rely and pray on this.!!

Every thing Jonathan says regards single ballscrew I fully agree with.!!

Well at least it's got two motors on the X-axis, but if that's what you get for £5k I take back what I said about it being worth a look. The machine in that video has lost most of the good things from the ones in the eBay listings. It uses supported round rails and worse small unsupported rails on the Z-axis badly orientated, plus the spacings between the bearings looks small. Rack and pinion not ballscrew, router not a proper spindle...

These are all things you should look for - profile rails (generally Hiwin is used), ballscrews on all axes (no need for rack on such a small machine), proper spindle not a router. Once mounted properly supported round rails aren't too bad, but since you're willing to spend £4k ish you should be able to get profile rails which will increase the rigidity which is the among the most important aspects of the machine.

The title of their other video of that machine says it all really - Low cost CNC Router, not 'High quality CNC Router'. The video shows the machine cutting pretty fast (due to the rack and pinion), but what about important things like resolution and surface finish? Not a clue from their video which is why you need to go and see it cutting.

What are you smoking ?

The whole conversation started off on fitting an extra ballscrew, clearly says in the ebay advert ballscrew with rotating nut.

I don't know why i bother, I don't have an axe to grind or anything to sell. It just gets repeatedly tiresome pushing fooking prams out of the way all the while.

To be fair the video was found via Google , not linked from ebay listing and is a year old.

Specifications subject to change etc...

Possibly drop the vendor an email with some of the questions asked here, coming across as a well informed potential customer saves looking like this ;-)

Did another company completely Strike themselves off the list even with apparent attempts to correct?

I don't know what that means John, but it sounds pretty rude and personal. You might want to calm down a bit :)

Jazz cnc do you mean ?
