Sorry about the delay, this is my busy time of the year and was out of town when a family emergency came up. Haven't had too much time to tinker. After MUCH adjusting I have gotten it to print o.k., it has some issues that I've been back and forth with their CS about. One is that at the end of any print one stepper motor will just ho off in the wrong direction while the other 2 home. They've sent a new board in my absence that I will be installing alongside a new stepper motor.
