hi

For example I have never worked with any CNC device before but I ready to learn
, a lot of the knowledge you have for your current job fit in quite well. maybe a good idea to register for the meshcam email lessons in cnc, it gives you a good all round understanding from the machine to the bits,

So say if I had the parts and plans to build one then it will be relatively simple for me to assemble
this is a good place to start, http://www.mycncuk.com/forums/gantry...g-machine.html

The best thing would be for me to ask you guys as what small scale machines do you guys have and what will you guys do to improve it
.

perhaps you will get the best advise if you describe or show examples of the parts you want to cut. the angles you require on some of the parts may make a difference to what advice you get.

If you have an example of a complex part you wish to be able to machine, post it, it will give the more experienced machinest on here an idea of what you will need.

as well as above, i would consider thinking about it in the following order

1. machine cutting area, what is the maximum travel you need in XYZ ( largest part you will build )
2. whats the toughest material you think you may use

understanding the above, will allow people to give you advice on the parts like motors, drivers, screws and pitches, electronics and general design.

on the more compex side, will any of your parts require a turret ( side spinning spindle for milling or threads ect ), or a 4th axis. If you not sure about this, post examples of the parts
