You need to state what materials you would like to cut and what size machine. I think you will find it difficult to find a machine under 2K that will be any good. Have you thought about building one?Quote:

Still trying to find out it's exact specs (it's like trying to get blood out of a stone) but basically it's a 3 axis machine for around a thousand Euros, for an extra 480 Euros You'd get a 4 axis Profi4 controller with next driver for my rotary axis (which is what I waiting to hear) it has supported rails all round, two Y axis steppers (one of each side), and a 130mm Z axis travel.
For me it's biggest plus is the steel frame construction and supported rails all round. It could be better in almost every department (has a distinctly home-made feel to it's construstion) but so far it's looking like that's the best there is for that sort of money.

60x20 extrusions... that is for 3D printer, not for a CNC. I would definitely not call that "Mini Muscle". Mini is right, but where is the "muscle"? Also that Z is, even if it uses ball screw, it is still using unsupported curtain rods. I'd be very careful with that machine... I think it promises more than it delivers.Quote:

I you want to buy something worth paying for then you have to be ready to pay for the quality. Personally, if I wanted to buy something I would buy this one:Quote:

...though, I have no experience of this machine, I think this is much better for that price than the previous links show. If it was me, I'd try to negotiate a price without electronics and would buy that separately, but if I'd not be able to build the electronics I'd buy it complete with everything.
Stop dreaming about getting quality products for peanuts. Just face reality and accept that you get what you pay for.
The other option is to do what many here and elsewhere did, build one from scratch. ...but even in this case if you want quality and a rigid machine you have to be prepared to pay for, so in reality I don't think you can build anything cheaper than £1.5-2k and still call it quality. This is an expensive hobby, like almost every other hobby.
Yes, that's what I am saying...Quote:

It also looks like you'd have huge problems fitting that with a real spindle, other than the Kress, or possibly a tiny Dremel.
While your take on things might well work for you I totally disagree. The real trick is in finding a cut quality you can live with at a price you can afford and with a learning curve that's in line with what you're prepared to put into owning one.
"Good enough" is subjective, and wel all have our own individual take on it.

That's actually cheaper than what you first linked to when you factor in import tax from US and spindle/router.Quote:

You could try the wanted section on here, ebay is only really good for new chinese machines or proper shop machines. Home machines always sell for far more than they are worth.
I know a few people have had success with chinese 3040 & 6040 machines but you need to have to investigate them well before purchase because the machines vary massively in quality and price.
You want 1605 ballscrews all round, nema 23's, supported rail at minimum but linear rail would be better!
...but of course... I didn't say anything about "good enough" because as you say, that is very much individual, but for that price you can definitely get something better, and if the one you linked to is "good enough" for you, than the one I linked to is a lot better, and that CANNOT be a disadvantage, especially since the price is about the same. Do you disagree with that? Do you also disagree with that the one you linked to is pretty much oriented towards the Kress or smaller? If you don't care, that's fine, but of course, it is a disadvantage, because the Kress is an angle grinder motor with brushes and it uses special collets, and those are expensive compared to the more common ER11 or ER16 type....Quote:

I am not saying that it is not good enough for you, I have no idea about your preference, but please allow me to think differently based on my own experience.
Camera...please get your head round the simple fact that you recommending something that's even more expensive that what's already ruled out on the basis of cost is very annoying and quite frankly makes you come across as a bit of a prat.
We're not discussing which is the best machine... we're discussing what we can afford.
And if you can't contribute anything on that subject then please don't contribute at all.
