Hello from Derry!

[JAZZCNC]

Ok well welcome aboard the DIY build train.!!

Kit's well there aren't really any good ones that I know about. Most kits are either low strength affairs or aimed at those who want to start really cheap and build using MDF or Wood using cheap components like threaded rod etc. All best avoided.!!

In my experience the best route is to look at other machine designs and Copy some or all of it.
Work out what portion of the build you can make your self and the parts you can't then have made by others. I make everything from single parts to full machines for people and there are others on here who will do the same or at least make parts for you.

If you can work with steel then building the frame from Steel box section is by far the cheapist way and very strong. If not then using aluminium extrusion is another good alternative but does cost more money.
Parts of the machine like the Z axis which people often struggle with you can have machined by others. Same with Motor mounts etc.

Electronics and wiring is an area that scares people but don't be afraid it's not nearly hard as it appears if done correctly, using correct electronics. The forum can help here with advise and guide you in the right direction.

Again BEST advise is DONT BUY ANYTHING until you have done some research and looking around to find the design that suits you. Then ask questions or advise on anything you are thinking to buy.

You'll be tempted to look towards Kits for the electronics but don't be.? Most are mis-matched and not suited to a balanced machine.
The electronics are the heart of the machine so using quality components that are matched will give you balanced machine that is reliable and accurate.
Cheap electronics are false economy in long run and come with high potential for hair pulling frustration. Best avoided IME.!!

So look around to get an idea of what tickles your fancy. Then start a build thread and throw up your design or idea and start asking questions.

I help lots of people and understand some don't want to go thru this process or have time for build threads so I'll PM you my Email in case you don't want to go public and phone number if you want a chat for advise. I'd rather offer this than see someone shy away from building or worse buy expensive rubbish!!
