General Mach Discussion / Re: add relays to Break out board schematics

« on: May 31, 2017, 03:39:55 AM »

You need to connect a protection diode across the relay coil and also check the model / rank of the PC817 opto as their maximum drive current rating varies from 2.5 to 30 mA and this will determine the type of relay you could use.

Maybe better to purchase a ready-made cnc relay board ( ebay from China ) ??

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.

Show"N"Tell ( What you have made with your CNC machine.) / 13 Amp plug - easy removal tool.

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
