A bit more progress on the enclosure. The engraving is done and the buttons sand blasted and anodized to match the knob.

Hi Joe,

It is best not to post the same question in more than one thread.

Everyone will probably have a different opinion based on their experience, likes and dislikes but my money would be on the CNC4PC type C11 board. http://www.cnc4pc.com/Store/osc/product_info.php?products_id=161

Sam,

When you say axis are jerky, is that just when starting and stopping (reduce acceleration in motor tuning) or does it just not run smoothly ?

Russ,

An alternative thought - if your tailstock is adjustable and in two parts then could you fit horizontal shims between the two parts to raise the height ?

Russ,

John Mac did the saddle of his lathe with a low friction epoxy compound - follow the link here http://www.machsupport.com/forum/index.php/topic,18189.0.html
May be worth further investigation (seems simple enough stuff to make).

Thanks Sam.
When I made the knob I could hear your words, saying "anno it"

Over the winter months the Synrad RF Laser controller went through much testing and as luck would have it, performs better than I had even hoped - the inbuilt, hardware PWM of the PIC micro is just brilliant and so stable under all the test conditions.
Now on to the enclosure which is really just a front cover because the PCB will be mounted on the outside of the laser housing and this cover fitted over the top.

1) The enclosure cutout and window milled to size. This cover started it’s life as the lid from an IP65 enclosure.

2) The front panel (1.5mm engraving laminate) which has yet to be engraved. I prefer to draw my work on paper, others prefer to use CAD - whatever, the end result is still a toolpath for the CNC.

3) The knob - perhaps doesn't look like it but more work has gone into this knob than I care to admit. It was turned, CNC machined, sand blasted and then anodized. And, like most things, if I had a second go at it I could probably make a better job.
 
4) Still some way to go but this is how the parts made so far will fit together.

I just dont see what the difficulty in the interfacing can be. I have seen the repraps, darwins, mendels and makerbots. What makes them so capable that any sherline, 80/20, taig cant do? Primitive by my standards. Do I have to be first? I want to modify my A2ZCNC, it would probably be best as an extruder anyway

Someone has to be first, why not you ? 

Start a new thread, post details of your progress and many more will follow (me included).
