My 1st DIY build

[JAZZCNC]

Eddy's correct about MDF it's false economy and while yes it may seem good for learning but reality is it's not that much harder to build one in steel and the learning is just the same but without all the hassle you'll have chasing accurecy and flex etc.

Electrics are easy really and with a little guidance you'll do it no problem so don't be afraid. There are a few products out there that make it easier depending on the size of the machine but I won't mention them yet as your many steps away from that yet and it will only serve to cloud the vision.
When the time comes we'll help you choose the correct electrics and guide on how to wire etc but first you need to start with the design style and size plus materials it will be built from. Then other things like linear motion components ie ballscrews, rails etc can be decided then from this lot the electrics can be choosen.

So first step design or Nick some others design then go from there.!!. . . . . . Ask anything your unsure about, no matter how silly you think it may sound ask rather than be unclear and get it wrong.

Good luck.
