i will collect all this data and make a construction for the router and come bake.

Hi,what is the difference between 3 and 4 ?QuoteSecond, i want woodworking and aluminum so. and it will work heavy.
3D modeling will need tall tool, right? what about the spindle type and model ?
For wood an aluminum with smallish tools then a 24000 rpm asynchronous spindle and VFD as abound on Ebay
will be fine, I would suggest getting the largest your budget allows. 2.2kW is about the maximum that you can power
with a the single phase 230V supply.
This is an example, I have no idea about this company or anything else, I picked so you could see the type of
spindle I mean:

The extrusion and aluminum plate will determine the machines rigidity. Many have constructed machines with these
materials and are adequate. The 20mm shaft will need to be supported. If it were supported only at each end it would
flex badly. For a machine of the size you plan square linear rails and re-circulating ball loaded cars would be better.
This is an example of cheap Chinese linear guides (trying to behave as THK units!):

Why? Some of the low cost AC servo brands, while still more expensive than steppers, they are not that much more and
leave steppers in the dust performance wise.Quoteby the way i want to use Siemens NX or Catia v5 which i familiar with. what is your opinion!
I have no idea what they are? This forum is about Mach3 and Mach4 both of which run on Windows OS Personal Computers.
You can induce a PC's parallel port to produce signals (via a breakout board) to control CNC machines. Regrettably the parallel
port has various limitations so it is becoming increasingly popular to use an external motion controller like an Ethernet
SmoothStepper or a UC300.
I use, and am very happy with Mach4 and an Ethernet SmoothStepper, and is my preference. Many other users will have equally
valid preferences, say Mach3 and a UC100 or UC300 or UC400.
