Longmill 30x30 will only work on x axis

I really need help! longmill 30x30 will only work on the x axis. The Y and Z do not work at all.They try to work but do not, motors ingage but that is all. .I have taken the unit apart and put it back together once, same results, checked all wiring ,connections all look good. What is next??? Could it be the slb? Switched the XY and Z axis around with no results.

Hey Rodney. It has been 10 days since you posted with the same problem. You checked all there is to check, you reasambled all there is to reasamble you switched all there is to switch. I think next is opening a ticket with the smarties at sienci and let them have a go at it.

@Rodney Has it ever worked since you upgraded to the SLB? You are connecting with grblHal, yes?
