May be an idea to check the new cable also to make sure that Pin1 goes to Pin1, Pin2 to Pin2 and so on. (Not all cables with 25 way D connectors are wired the same).

Hi Chris,

Do you think something like this could be adapted to smaller scale higher precision work ? http://www.vectric.org/labs/index.php/laboratory/item/get-kinected-to-your-cnc

Hi Todd,

I would be most interested to hear how the digital voltmeter performs.

I don't have any backlash problems with my multi-turn dial but obviously there are good ones and bad ones and perhaps I was lucky.

Hi Mikee,

All of us, yourself included, each have expertise in different areas or directions and it is when we all come together, on a forum such as this, that a tremendous amount of knowledge and experience becomes available (bit like the individual pieces of a jigsaw making the complete picture).
Others will help you and you will in turn help others - it doesn't matter how clever another person seems to be, there will always be things that you know that they don't - that is the way it is.

Gerry,

Looks like the motors just have the one set of bipolar windings at  6 Amps per phase.

Hi Mikee,

My lens is made from Zinc Selenide and is AR coated on both sides - cleaning it is a delicate process which I really don't want to have to do very often so I use a 'co-axial, air assist' at all times and I have adjustable pressure / volume settings that I can select for different jobs. Because the lens assembly is always above ambient pressure during use it keeps the smoke out.  
You can see the nozzle and just see the air supply line in this photo http://www.machsupport.com/forum/index.php?action=dlattach;topic=12444.0;attach=21034;image

Hi naPS,

Thanks for the feedback (there is now 6 or 7 of us using the plugin  ).

If you do decide to go for something like the FSE option please report back on your results (even though it will not be Mach driven).

Of all the laser stuff I have completed so far there has only been one job where I have combined two different power levels http://www.machsupport.com/forum/index.php?action=dlattach;topic=12444.0;attach=25183;image so I have not really given a power changing option serious thought. Something more to add to my 'to do' list I think and thank you for the suggestions.

i_r_,

Just an observation, but it is always best to have a dedicated PC, with minimum install, just for Mach and then keep your main PC for the CAD/CAM work etc.
(My machine PC is nothing special, runs XP sp2, and was obtained 'second user' for silly money).

I really need to get a CNC!

Is it possible to survive without a CNC ?
