This image is 106mm x 130mm and comprises entirely of laser dots on some scrap MDF. It took 80 minutes to complete but the interesting thing is that the same GCode could (theoretically) be used with an impact magnet and again it would take 80 minutes to complete. Higher resolution and larger images would, of course, take longer but I still have a bit of reserve as far as the speed settings are concerned. It is all a matter of putting theory into practice

EDIT. I have attached the .jpg / .bmp and GCode if anybody would like to try it.

Hi Bob,

Yes I think it is electrical noise as well.

Lots of people have had this same problem and the cures have turned out to be various. A forum search should turn up lots of information but try re-routing your spindle cable away from other wiring, make sure you don't have any 'earth loops' or 'GND loops' and if you are using a VFD that it is properly earthed (at one point only).

Just a couple of things to try.

Hi John,

Something I forgot to mention in the previous post is 'Air Assist'. This is pretty essential when cutting wood as it blows the carbon (which is laser resistant) out of the kerf and allows better laser penetration of the work. The disadvantage is that tabs may be necessary to stop the small parts from being blown away but it does allow cutting right through the work from the same side.
It is best to use an oil-less air supply as this will prevent any possible oil contamination of the focus lens but shop air, with the necessary (paint spray) separators / filters works just the same.

Something for you to try perhaps ??

Excellent work John that looks really, really good.  

Sorry to hear that you can't get any results from the Impact / Laser plugin but there are a lot of conditions which have to be met in order for it to function correctly.

You may want to try DotG as this produces GCode which you can run at any speed (to suite your diode). http://www.machsupport.com/forum/index.php/topic,12444.msg141147.html#msg141147

Keep posting the pictures and details of your setup as I am sure there are many others that wish to follow your progress.

Merry Christmas Dave.

I hope 2012 will be a better year for you than the last 6 months of this one

Would anyone happen to know if I can wire the LCD and the shuttle pro 2 together at the pendant and then run one cord to the PC? Or is this too much voltage.

Hi Dave,

Are you just meaning the supply for the backlight for the LCD ??

It is perhaps UK style humor but for anyone who remembers the Fork Handles sketch ( http://www.youtube.com/watch?v=Cz2-ukrd2VQ ) - this was shown on TV last year but repeated again recently.   http://www.youtube.com/watch?v=kAG39jKi0lI

Hi Fred,

All of your previous set-up will be stored in the .xml file (named as the profile you are using .xml) and located in you Mach3 folder. Copy this file, save it somewhere safe (memory stick is good), then use it to over - right the new .xml file after the re-install. It is also wise to keep a copy of your license file and screen set, just in case everything gets deleted.
