Im new, am a 3D designer. Need a New cnc machine and need advice and guidance

[njhussey]

I think I will still have to design around the rails, its the way I have been taught and may sound odd but without a reference it becomes difficult to scale the machine,for me anyways.

Are these chinese CNC parts decent quality or are they to stay away from?

A reasonable size sounds reasonable haha. I think I will just do that...I can expand once i get my head around everything and have sufficient finances in the future :)

What is the max size you want to machine?

As a designer you'll know that first you need to identify the requirement before you can come up with a design/solution. Set out what you want the machine for, then you'll know what size you need to design. Then you can draw your rails and email Chai at linearmotionbearings2008 (ebay store, though don't go through eBay as you get better prices) to get a quote for the rails and balls crews all in one go, the more you order the cheaper prices he'll give you.

What you're saying is a bit like "I've got a 1000kv 24A out runner. ..I'll design my RC plane round that...which although can be done it's better to say I'll design a 1000mm span plane and then after estimating the Wright of it select the motor, ESC etc...
