Ok Back to the drawing board as someone burnt though memory card ribbon when soldering up a powerless USB plug. (Doh) as i have been having some brownouts I decided to install this kit. will review it soon.

Never mind so time for safety panel Mk2. just going to order a second temp sensor as then ill have water input and output readings.  Jumped on to Lightburn and just adjusted will post SVG once I have finalised it all.

So tonight little operation on the k40 is to first of all cut another test panel as my 13mm led bezels were a little tight. Will then cut a template panel for cutting the hole in the metal work. before drilling fixing holes and taking a Dremel cutting disk to the panel.  I will be doing this off the machine. vibrations love to mess with mirror alignment.

The wiring of the system:

Wiring up the emergency stop:

The emergency stop is 4 terminal so will have both Live and neutral running through it on each side of the switch. then to the power switch on the main panel.

Wiring up the LED’s

Pump active LED will be wired in line before the laser on/off switch but after the water pump switch.

I will splice the laser active LED to its switch. so when on its lit when off its not will take some images and add them later.

Water flow switch

After looking on Amazon found a cheap one from China will give it a test drive. as will be open when water is running through it going to fit it to return pipe to the bucket.

will wire this before the laser active switch so will cut output if pump or water fail will shut off the laser form firing causing any damage.

Argh, amazon prime was out of stock of second digital temp gauge so have had to order off eBay now waiting on bits before I start cutting up the machine, so there will be a part 3 to follow soon as I have all the bits in.

probably Monday Tuesday next week.
