big budget cnc

[Desertboy]

Morning, do you have a budget in mind for this?

[Boyan Silyavski]

Your idea is riduculous. Be realistic and prepare a budget of 6k for simple machine this size or better 8k for a Ferrari

Just copy my second machine and it will do whatever job you throw at it. No need for the heavy duty Z, just 3kw spindle. I have plans for it that i sell to people that know what they want and i offer one to one support for the build.

Tool changer is not needed for kitchen jobs and it costs 3k at least and you need a controller that could do the job.

20k machine will NOT pay for a month. You need to have factory and at least 10 people working for you for that to happen. But then you will not be looking at DIY machine, right.

Maybe a second hand machine around 10k is better for you and will start making money at day 1. You will need 1/2 year at least to build your machine, even if you have the detailed plans of my machine or any other. Its not a one day job. Most people here like what they do and its their hobby, side business or similar so they take their time. Even if i have all pieces i will need a month to build it.


That may answer all your questions. And yes, crappy machines not with proper linear bearings will make you pull your hair off and will be total waste of time and money. MONEY.

Hi Peter,

If you cannot stretch to linear rails at the moment, you might like to have a look at mechmate design.

I'm not necessarily saying use the whole mechmate design as its a little dated, but it has a lot of features you describe in your initial post.
Lots of info for making roller bearing rails, rack and pinion, and other stuff

Personally I would always keep the gantry as short as possible. 3m will offer huge challenges.

Cheers
