Just tried swapping inputs and the problem followed. So do you confirm that its the board?

Thanks Hood, I have managed to check pins 3,4 and 7 which are the direction pins for X,Y and Z axes and all 3 behave the same way, ie. 0V for one direction and 5V for the other.
The board I am using is one I got off of ebay from China I think, which looks great as it will do all 3 axes, limit switches, E stop etc. all on the one board. I think, however that the problem must lie on the board, but wouldnt know where to start looking for that one!!
I have sent them a message asking for help, so hopefully I will get a solution from them, unless you can think of anything else I may have missed?

General Mach Discussion / Stepper moving in one dirrection only

Good day,
I need some help with my new setup. I have connected up 3 steppers and run a test program for about 10 hours without incedent. I shut the system down for the night then started up again 2 days later, but now the Y axis will run in 1 dirrection only. It is getting the move input but just keeps going clockwise.
I have checked the ports and pins configuration and it is unchanged. I even checked the video clip of the test to make sure I wasnt going crazy.
Does anyone have any suggestions?
Thanks
Tony

Hello there,
I have been using Mach on and off for about 6 years. I originally had some help converting a small cnc mill and lathe and the guy helping me introduced me to Mach.
I am currently working on building a cnc wire edm and have a puzzling problem. The X axis will only turn in one dirrection even though the read out says it is going both ways. I have swapped the axes over and the situation is the same.
Does anyone have any suggestions?
Thanks
Tony
