Hi William,

Enter the data then press the 'Return' key. 

(This rule applies across the board with Mach and it just becomes routine so we perhaps take it for granted that everyone knows about it and it doesn't get included as an instruction).

William,

I am sure Graham will compile the code for you but in the meantime have a look at the Pocket Cutting Wizard within Mach. You would perhaps need to use two instances of the wizard, one for the pocket and one for the recess but they could both be combined into one final GCode file.

As far as I know, nobody has used one of these boards yet or at least reported back on it's use and as you say it does seems a logical progression.
I am a bit strapped for funds at the moment otherwise I would buy one just to try - Somebody has to be the first, why not you ?

Hi Thys,

Have you looked at free trial download of Vectric Aspire or VCarve Pro  http://www.vectric.com/WebSite/Vectric/products/download_products.htm

They are not really CAD/CAM as I would describe it but they could be good for flat-pak stuff like cabinet fronts etc.

Nice looking machine you have there Tom.

I would be inclined to opt for 2000 steps per revolution as I am not convinced of any real benefit from going higher.

Hi Mikee,

Once you have it all set up and working correctly that is the time to consider increasing the motors current settings if it is necessary.

Sounds like you are well on your way - don't forget to post some pictures of things that you make with your new CNC

Nelsonk11,

If you post your question as a New Topic in the General Section more people will see it and it will get better response.
This thread is really just for introductions.

Mikee,

Change all axis driver setups to the same config.

The Mach setup videos are here http://www.machsupport.com/videos/

Mikee,

As far as I can tell switches #4 and #8 are unused and should be ignored.

You have set #1,#2.#3 for 1/4 step which is OK but 1/8 or 1/16 would be better and give a much smoother motor response.

You would be wise to initially set #5,#6,#7 (currently 3 Amps) to a lower current such as 1.5Amps for testing and setting up as this will dissipate less heat in the motors etc.
