Hi there,

I think i have found an new hobby, i can programming in php, js, sql, c and as last i have found Arduino.

What u can make with Arduino, unbelievable?! I have do a few small projects, make a gps tracker, automatic chicken house opener and more stuff like that. Now i want to but an CNC router to mill PCB plates and some aluminum parts. So i don't wanna have trapezoidal screw, the holes must be center in the lines.

What is better? An 3040Z-DQ machine from Ebay of a OMIOCNC X3-300?

I have also saw the Stepcraft 420, but someone told me that is not a very good choice, with the copper wheels on the aluminum rails.


I can spent a $ 1.500,- or 2.000,- but if i don't use the large of to large machine, than is it a waste of money.

I search for a nice and small machine in that format like the types above. I was thinking, when i not use the machine very much and it has a water-cooled spindle, is that ok? because the water/machine coolant/white water is standing there and waiting for to get died. Maybe is air cooled better for me.


Here some specs of both machines. Can some give me some good advice?
