Hi guys, Currently waiting for my parts to arrive for my first cnc router built! Now i need some guidance in my search for a Router/Spindle. Because we have 220V in europe so the once i read about on the forums cant be used here I plan on doing all kinds of work on my machine, like woodwork, aluminium and if possible PCB's. I am not sure what kind of rpm's i need for those materials to start with (any link or readable material on this is also welcome!) and most of the machine's i found were not changeable. After some searching i found the following routers and i hope you guys could give me some advices about this: First is the makita RT0700c which i can get for 150 euro on ebay. Clamp 8 mm Max. cap. depth 35 mm Speed range 10000 - 30000 rpm Machine voltage 230 V Power consumed 710 Watt price tag: 150 Second is the Kress FME 1050-1 which i can get for 180 euro. Clamp 8 mm MAXX-Power 1050 Watt motor Effective power 560W Speed range: 5.000 - 25.000 rpm Motor weight: 1,7 kg price tag: 180 http://www.amazon.co.uk/Kress-1050W-Milling-Electronic-Control/dp/B00DOTGRRY Another Kress FME 800-Q which i can get for 165 euro. Clamp 8 mm MAXX-Power 800 Watt motor 420W effective power Speed range: 10.000 - 29.000 rpm Motor weight: 1,4 kg price tag: 165 I also found the bosch GFK600 which looks like the bosch you guys use but without changeable rpm and for 100 euro's more maybe through phase modulation i can slow it down. But i am not sure which is any good and what do i really need!?... Any thought on this (pro's / cons) or others ?
