greeting. MTU is close to completion, now it becomes problematic. I don't have any experience with electronics, but I have a friend with some knowledge who helps remotely. we can't go on without the wiring diagram for the stepper, servo parking and parking brake led. for steppers there is an old and a new scheme. offsets are a special problem for us. it would be nice if you could write for those of us who don't know, offset xxxx is for throttle 1, etc. I see that piki has put everything on the forum, but I note that I am doing everything according to Karl's original design. thank you
Hi Pele.
I also struggled a bit with the wiring, especially with the stepper. I'll try to help answer as I know Karl is very busy getting ready for a Sim Conference next month.
1) Servo - I haven't hooked mine up yet but I have used servos on my Overhead panel. I found the Pololu servo controllers work great and is recognized by Prosim. I have not tried to connect it to an Arduino card.
2) Parking Brake LED - you need to add a resistor and connect it like Karl shows on this page.
3) Stepper - There's a few threads on this one but I had posted one trying to get clarification on the wiring. My motors work but still not sure I have everything connected correctly. There's a wire connected to VCC that I didn't make Take a look at this thread and see if it helps you.
