Quoted from Spyderturbo007:I've been through that website a couple times and while helpful, it doesn't point me in the right direction. My issue is I need to know where to look for the problem as opposed to going through the entire game when something happens.
In the past I'd go through a whole machine, sometimes it is easier than muddling around trying to lock down a single issue if you are starting with an unknown pin.
Cleaning and adjusting all the relays and steppers can give you a good hands on experience.
