Hi Shanren,

I think that line of code should read :-

Code: [Select]

Do While Getvar(3) < 360.000 * Getvar(8)

Hi Jeff,

Perhaps take a look at and run some of the practice Gcode files in the .zip file here: http://www.machsupport.com/forum/index.php/topic,18345.0.html  - it may help you to get to grips with using Mach3.

It was common for a spindle brake to be used to enable faster tool changes to be made on the ATC equipped machines but changes to certain industrial regulations have now made cutting device brakes mandatory on some machines (typically, circular saw benches) - perhaps check the regulations in your country.

I would be inclined to let the drive control the braking.

I have visiting friends from the Netherlands so now we have another version.

I do not have any melinex but I do have some copper shim stock and a mill. Can I make a US version with those you think?

As my Mach3 laser cutting Gcode for this little device is less than 500 lines I have now included it into the .zip file.

This is probably just a UK related issue but the shape of some of my mains plugs makes them rather difficult to grip and remove (especially when having slightly greasy hands). An easy removal device can be purchased but with a laser and some melinex (or similar electrically non-conductive material) they are very easy to make. This little device is easily fitted to the plug and it enables it’s quick and easy removal from any socket (using just one finger if desired).

I have included the .dxf file if anyone wishes to make their own.

Please take note – when laser cutting anything (particularly plastics) always use adequate fume extraction and take precautions never to inhale any of the vapours or particles produced.

EDIT: Reference to 'electrically non-conductive material' added after Brett kindly pointed out a weakness in my product description (thanks Brett).

You have created duplicate lines in the generated .dxf

I can measure 50vac between the router and the controller earth when the spindle motor is running

What you are describing is a serious and hazardous fault which could possibly result in loss of life.

Before you do anything else cure that problem.

Fo any equipment that is connected to incoming mains electricity, every metal (or electrically conductive) part that an operator can touch must be correctly bonded to protective Earth. There are variations (such as double insulated) so check the electrical regulations that apply in your country.
