Need Help!!
« on: April 28, 2017, 06:59:20 PM »
Hello, My name is George and I am a Fabricator living in Australia in sunny Brisbane. I am wanting to build a CNC Milling Machine to produce Accurate components in Aluminium with a good surface finish. I have purchased an Optimum Bf46 Vario fitted with Ball Drive Shafts. If you dont know, the BF46 is a Large, Sturdy heavy Desktop Mill. Approximately 650kg. Its designed in Germany and produced in China to German Specifications.
     I need help choosing what version of Mach would suit my needs. Mach3 or Mach 4
     I need help choosing what Motion Controller/Breakout Board to choose. Vital CNC, CS Labs, PMDX, CNC4PC, etc....
     I need help choosing stepper, stepper hybrid or servo. and associated drivers.
  I am wanting components that are good quality. I would rather pay extra now and have less problems down the line.

Any suggestions will be much appreciated.

P.S. This is my first time on a forum. I dont even know if I am in the right section.

Hi George,


Unfortunately there is no truly definitive answer to the questions you ask as it is all a matter of personal opinion.

My opinion (based on old, well tried and tested, stuff)...

Warp9 ESS
Gecko G540
Stepper motors

Others will, I am sure, choose an entirely different set of products.

Not very different, really:
Windows 7 (because it works fine and is easier to come by)
Mach3 V.062 (and NOT the latest V.066!)
Warp9 ESS (definitely)
Homann Designs MB-02 break out boards (2 off)

Now motors ... I think steppers will have enough grunt to drive a machine of that size. You would probably need the largish size of stepper, and a 3:1 toothed belt reduction using GT2 belts ( I suggest 9 mm wide) is always good.

Alternately, DC servo motors with 512 line encoders and Gecko G320 drives and a 3:1 GT2 belt reduction WILL work fine - I use them myself.

Putting all this together from scratch ... hum ...
Can I suggest you ask Peter Homann at Homann Designs (Vic) for help. He can sell you almost all the bits you will need, and he offers very good local support.
