Hello ....another rf 25 enquiry

Hi everybody i am a complete novice to machining , cnc etc but really enjoy making stuff .

I have a RF 25 that i use for hobby machining parts for motorcycles & small bits for models , its a lot of fun trying to nut out how to do things but it gets a bit frustrating trying to get repeatability .

Now to the point ... i have been looking at converting my machine to CNC ... lots of time on the net trying to work out whats the best way to go ... lots of great ideas here on CNC zone .
I have been looking at a Cnc controller kit from Homann Designs in Oz ,

Geko G540 controller
387 oz/in , 3.5 a stepper motors
7.3 a , 48 v power supply

Does anybody have any practical experiance converting these machines here in Oz ? , any ideas if this kit will do the job on this size machine ? to small , not enough amps ? enough volts etc ,

Any thoughts , ideas would be gratefully appreciated .

Many thanks
