Hi. I’ve just stumbled upon these cnc routers and fancy one for making a few hobby bits.
Is there a cheap machine that will do a fair job on a 40x40cm workpiece before I decide to bite the mullet and spend a bit more
Thanks

Latza Welcome to the forum. What have you stumbled on?Quote:

I havnt found a machine yet. I’m contemplating making one. I can fabricate and make things so that’s not a problem but I don’t know anything about the motors and drivers at all
Is there a fairly powerful motor kit with everything in that I can buy and bold to a table
I’d like to be able to fit a 8x4 sheet if possible
Hi Latza,
Strongly advise you to search around the forum and do some research before buying anything. The cheap machine kits you'll see are often not very good, same for kits of components, they nearly always have components that are not correct.
Building a machine isn't difficult if you are handy with tools and can fabricate but it does require planning and good understanding of what you'll need. Do the research before doing anything else and look at other build threads. Then start a build thread of your own and ask all your questions in that thread. This way when people look they can go back and see the whole story.
If you rush out and buy stuff without the research or no plan on machine design then you will 99.9% buy the wrong stuff.
Thanks for the above.
Is this any good ? https://rover.ebay.com/rover/0/0/0?m...2F254518989549
I wouldn’t mind having a little bit play around with a cheap one before I spend the money on making a big one
Nope!Quote:

The answer to the question "Is this any good" is NO. . . .BUT . . . . If you said is this any good to learn CNC with then answer is Yes. Just don't expect to do the things you see others do with more polished and better spec'd machines.Quote:

So as you see you will learn CNC one way or the other, some times it will work and you'll learn how to cut with it, most of the time it will be broke or frustrating the fu#king daylights out you and you'll learn how to fix a CNC machine.!!
Will it teach you how to build your own or what components you'll need then honestly no it won't. Because they are rubbish and anything used on them you wouldn't want on a decent machine.
Will it enable you to learn how to operate a CNC machine then yes it will, when it's working.! They are actually very good for learnig on because they are cheap, just don't expect too much from them and don't waste any money or time trying to upgrade or make better, because you honestly can't make a Silk purse out of a sows ear.
However, if all you want is to learn how to code and operate a CNC machine then you don't actually need a physical machine, it can all be simulated.
Most control software will allow you to run in demo mode and will run any G-code you produce just as if it was connected to the machine.
The CAD/CAM side is something you can and would learn without needing a CNC machine and again any code produced can be Simulated either by G-code Sim program or directly in the controller which would run the physical machine.
Honestly rushing to get a CNC machine is the biggest mistake new people make and it nearly always end's up costing them lots of money or worse put's them off.
DIY building isn't difficult and you can build a machine that will match many industrial machines for a fraction of the cost, but it can not be rushed or short cuts taken to do it correctly.
An indication of your budget would help, decent kit costs decent cash, as advised you really need to research the build logs.
