Quoted from Clnilsen:Do you get any errors in the backbox head test (T15 test) in the firmware? This would be great to confirm.
If possible, could you do me a Huge favor and confirm as much of the wiring as you can - i.e. at least confirm which pins are used on the JP 206 / 208?
I've got a Doctor Who in front of me with the motorized Dalek from Basement Arcade - is this the same kit you are struggling with? Happy to take any photos/do any testing you might need.
Let me know if I can be of any help.
