Thank you Windell
The mystery has been solved.
I have built my own machine from scratch and the motors that I used (nema 17) had exactly the same colored leads as those shown on the EggBot web site. I had wired the motors as per the instructions shown in the Eggot assembly PDF.
I have since discovered that although my lead colors where the same the actual wiring was different.
The motors now run as smooth as silk.
I am now smiling and thank you for your attention.
