Hello, here is my new machine

[A_Camera]

I disagree politely ! THAT is not what I said.

I said you as the seller/maker can get the parts made (very much) cheaper elsewhere, and as such it is not *economically productive*/worthwhile to make them with a small, cheap cnc.

I don't think you disagree, but I think I misunderstood what you meant. I meant using a cheap CNC can be profitable. Of course, MAKING a small CNC aimed at selling AND making profit on the CNC is a different thing.

Making (or buying) a small CNC, buying or making parts to make it, and then use that CNC to make profit is indeed possible. Surely, you can't disagree with that. My hobby is entirely financed, with profit, by making these adapters:



Of course, only the bottom part. The top part is bought on eBay because that requires more complicated process and not just a mill. Never the less, something like this is enough to make a hobby profitable, including making or buying a CNC and all the parts necessary. Of course, the price or costs of the CNC must be kept low, otherwise there will be no profit, your 100k€ machine is out of the question, that requires very high volume sales and professional use at least 8h/day for 5 days a week. ...unless you have an even better idea for a product which people are ready to pay MUCH more than $100 a piece.
