Neil had asked me to improve outer cover of the job
So have designed it using solid work in 2 parts and final product looks as below :
Connecting 3 D printer AC mains cable
Connecting 12 V power and 3 core PC communication cable
Placing the device beside 3 D printing and operating the printing using the device.
As SSR being used is rated at 25 A current it can be used to drive and control almost all the machineries used in our lab.
