Hey guys, I have an open ticket regarding an AltMill SLB issue that’s been unaddressed for a week. The board is nearly unresponsive short of homing.

Can a team member take a look at Ticket #36572?

@Shamrock-A This is a user forum so you might not get a response from Sienci support. But I will tag @kellyz for you.

I was reaching out as a last hope and actually already had a response! But thank you for asking.

@Shamrock-A Are you back up and running? If so, what was the solution?

Kinda sorta. Everything is running but I need a new SLB-EXT. The issue was the controller failed and won’t connect to the spindle. They are sending me a new one but I can still run the spindle manually. Overall a good experience with their service.
