My board continued to track RA all night on my test bench, with minimal heating of the stepper. All good.
The problem I have is that the 12V connection is unreliable, a brief interruption in 12V will crash the CPU and lose connection with ASCOM.
Has anyone used a locking 12V connection? I think a locking power connector is essential in an outdoor environment. The common DC power plug can easily be pulled out accidentally - at exactly the wrong time!
One option is to solder wires to the 12V input on the PCB, about 6in long. Then fit a good quality RC power connector like the XT30.
Does anyone have any recommendations for a reliable power connection?
