And I was counting on you.  

I must have upset someone at the UK Border Control Agency because everything I have imported lately has been seized by customs and swingeing import duties levied as well as the 20% VAT. Surprisingly the goods from the USA seem to be getting hit worse than those from China but I have been unable to get an explanation of the reasons for this. I think I will just have to lay low for a while (nothing to do with the fact that I have overspent my CNC allowance and I am broke   ).

A quick bench test, just check it all works OK now that it has been assembled up.
Here, the laser was fired for a 1 second burst (pressing the trigger then camera shutter almost simultaneously) at a setting of 20.5% PWM which, according to the Synrad power graph is approx. 25% of the lasers output power. It makes an instant and satisfying 'pop' as the cardboard ignites.
This is the beam straight out of the laser (approx. 6 mm diameter) without any lens, when it has been focussed to a point the size of a pin prick (0.04 mm) it should be quite awesome.

Hi Mike,

Would be really nice if someone bought one and tried it out

They are what they call Cross Roller - I bet you have to keep them extra clean as the rollers are exposed for most of the time. There is more info here http://www.thk.com/eng/products/class/crossroller_g/index.html

I think you need to go into motor tuning and set up your motors (Config / Motor Tuning). Increasing the acceleration will reduce the start and stop delay. Don't forget to save your settings / changes for each axis before moving on to the next.

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 ?
