First things first great site i have found it very helpful in my quest to build my own cockpit based on the 737.
I am having an issue with my stepper motors 28BJY-48 type converted as per the instructions and connected to the A3967 driver board wired as per instruction. I am using an Aduino Mega 2560 R3 as my master board with the simvim firmware and the Uno board as my slave also with the firmware for stepper. Both boards connected via TX and RX as per instruction, both boards earthed master board is connected to PC USB and the slave a dedicated 5v via USB phone charger. stepper DIR into pin 13 for both steppers DIR's are linked and the steps into pin 10&11, using AT_Motor and these lines in the Data file.
G10 AT_MOTOR s=3
G11 AT_MOTOR s=3
I can get the steppers to move when AT is engaged but only in one direction. In the Calibration tool no mater which arrow i click it rotates in same direction i am using xplane 11 with 737 Zibo mod.
I did notice only last night that the TX and RX on the Slave are not flashing, i do have flashing RX on the master board i have ordered a new uno which should be here tomorrow in case it is a bad board. can you offer any further advise or suggestions on the steppers rotating in one direction or point out what i could be missing.
any help you can offer would be very much appreciated.
Thanks in advance
