I have lost count of the number of wires this 4 axis cnc controller has but as you can see they are starting to look like less of a birds nest!

Above is soon to be replaced 24vdc supply, relays, drive power supply, spindle controller and a motherboard for the 4 stepper drives.

On the Left is a 2.2kw VFD to power my spindle, a bank of fuses, soft start timer to short out the current limiting resistor and a bleed resistor. The transformer is huge 1000va beast to feed the steppers with the juice they will need.

Many hours were spent making custom shielded cables and then working out how to ground the many different systems together without forming any ground loops.

Each drive has its own heatsink and fan that….

Pulls the cooler air from the rear of the large cabinet. As I plan to cut a lot of carbon I hope to have this system in a sealed enclosure, hopefully the fans create enough air flow to use the large surface area of the steel enclosure to dump the heat.

So some big buttons, a few lights and a joy stick complete the package!
