can you clarify what you mean by 'the directions of the steppers change'? What software are driving this with and what Breakout board?
ok so lets say i have just set up my machine runs fine cuts fine if i press left arrow key bed moves left and so on .. i finish the job and turn every thing off ..
but when i turn every thing on to start a new project and press the left arrow key it goes right or z goes up instead of down its random then i have to go into ports and pins and set the directions up again then it will run fine till i turn it off again its like it gets a power spike on startup that flip the direction on the steppers and its not always the save stepper that need sorting

all motion control products stuff Breakout board ect
