To that end, I have done some more work on the rotary table control system. I'm putting together the control box that will house the power supply, switches and electronics.
Here is a photograph of the front panel, showing the LCD display, menu scroll through paddle switches and menu select button:-
The rectangular holes for the LCD display and the paddle switches were created on the milling machine. The paddle switches snap into the holes and are held in position by integral spring clips. The LCD is bolted in place using the protruding 6BA bolts that hold the PCB stack together. Here is a photograph showing the arrangement of the electronics and switches on the rear of the panel:-
The power supply will be fitted in the space next to the switches. The mains lead will enter the enclosure through a strain relief gland. A socket will be fitted for the stepper motor drive pulses.
I'm looking forward to getting the control box finished. The automated rotary table will then be ready for use. Just in time, as I am now going to order the material to begin the construction of the tube bundle thrust chamber.
Look out for more updates over the next few days.
