Quite a while ago I managed to break something with the wiring on the control panel that caused a glitch on the programming for all the switches so I had the TM7 board 'temporally' on the CANPAN. Several months later and several more servos and relays now online and I realised that I had to reluctantly return to the control panel and try and figure out what had gone wrong. 

• Disconnected the LED wiring from the circuit board (no change)
• Fiddled with some switches and and found a fault, with not just 1 switch but 2 of them! Typical! 

So two switches (which equals 8 functions) now temporally out of action. 24 functions still working and I now have 11 functions programmed, with two more functions coming once I get 4 more servos installed. So not to worry too much for a while. The great thing about using CBUS is that I was able to simply re-programme the event functions that were using those switches over to other switches and carry on with minimum fuss. 

Well to be quite honest I have decided that the panel I have built doesn't quite meet the bill. It was a good first attempt but I think I need to have the LEDs on a mimic panel map as that will be far easier to read and install plus I need a code sheet on the panel itself so I know which switch does what event. Also I think having the panel slot inside the box instead of hinging ontop of it will look far neater than it does now. Also using toggle switches that return to centre - maybe I should use push buttons with an internal LED as having had 2 toggle switches fail so quickly doesn't give much faith in them.

Mimic panel diagrams and this is my strength having drawn one for real for a heritage railway. I drew something quickly on paper  and pinned it to the ceiling (no walls in the loft) and then proceeded to draw something more professional on AutoCAD for all my boards and functions so far. How I get the LEDs onto the underside of the mimic panel diagram and then attach to the sloping ceiling well that will need a bit more planning but should be fairly doable except I will need a wiring bundle (x12 wires for each CANPAN) to go under the board and up the ceiling from each splitter board.
