Hi Jumla,

A couple of things you could try;

Check the voltage level of your LPT Port 1 to make sure it is 5 Volt TTL standard and not 3.3 Volt TTL.

Try configuring the Digital Trigger output as Active Low (this then connects to your laser PSU’s  TTL(L) input).

Choose an output pin number for your Digital Trigger that is not used anywhere else in your setup (even if any conflict of pin number is mapped to a different LPT Port).

Here is an interesting natural science experiment / project for children and others, like me, who never grow-up.

For Millennia the basic building block for nature has been observed and extremely well documented but only in relatively recent times (since the introduction of our Hindu-Arabic numbering system) could it be expressed so easily in mathematical terms.

The ratio 1 : (1 + √5) / 2  is all around us and because it occurs naturally we perceive it as being ‘pleasing to the eye’ so to this end we have duplicated it in our architecture, art and just about everything else. We call it the Golden Mean.

It should perhaps be emphasized that this ratio it is not a law, carved in stone, because there will always be exceptions it is merely a trend but, in nature, it occurs more often than not.

The infinite pair of  numbers in the Fibonacci series 1,2,3,5,8,13,21,34,55,89… are again in exactly the same ratio and if we look closely at our plants, fruits, trees etc. these numbers and the ratio are there.

Getting back to the experiment / project, the attached .dxf can be used to make a set of callipers whose points follow this ratio so that we can measure the things around us, learn from the experience and perhaps even inspire others.

(these callipers are perhaps not quite as accurate as I would like them to be but it’s a start).

I may be way off target here, but if it was me I would also fit a short sleeve (clamp ring) over the ball-screw so it mechanically cannot move the axis far enough to loose the bearings etc. just in case the set limits are accidentally overridden.  ;)

Hi Pete,

If you could zip and post (or e-mail me) a copy of the GCode which has the repeatable problem I would be happy to run it here and if the problem shows on my system then perhaps I could suggest a possible solution.

Hi Gary,

Welcome to the forum.

I look forward to seeing some pictures of you project and hearing of your construction techniques etc.

You could post the information as a new topic here http://www.machsupport.com/forum/index.php/board,27.0.html as I am sure there will be much interest.

Nice one Kenneth  ;D

Perhaps changing the text a little could help.

Try Speak " Milley meters " or perhaps some other combination.

Excellent and extremely neat wiring job Hood.  8)

( I used to visit Portsmouth quite frequently and always wondered why most of the house's had grey painted fences, gates and garage doors etc. - then it dawned on me - the Dockyard's and 'Battleship Grey'  ;D ).
