In some cases where CNC router is to run with mist/spray coolant continuously, an external control unit is required to house and protect the control electronics from the water ingress. For example the use of a sprayer cooling system can greatly improve the stability of cutting aluminium and can help keep materials like acrylics cool when machining. We use the dual nozzle Fogbuster system when running with coolant.
High quality connectors
We use high quality IP67 connectors to interface with the controller. The cables are managed in the rear of the machine and usually have 2-3 metres of length between the machine and the controller.
