So I have this 883 Pro (#1086) that’s sadly been relegated to storage since I had to move across country during those “Covid years” and then moved from tiny apartment to tiny apartment. Now I have it out of storage and want to revive it. I believe it’s still on the original firmware and the old laptop I used with it has Motion build 513 at the moment.
Back out of the box, I power it up and the spindle automatically goes to the right and doesn’t stop – it keeps grinding into the limit switch. This scares me crapless so I just turn it off until I figure out how to stop that.
So that’s question 1: how do I stop that? Question 2 is I bought some Super Lube and likely need to give the whole thing a run-down but is there a ‘renovation’ guide so I can get this old man working properly? Not really sure how to approach this. Any info is appreciated!
I’m still trying to figure out why X is so loud during initialization – and not stopping at the Z limit switch. The machine has been lubricated, but the X travel just sounds like it’s slipping (it physically moves fine). So I have to abort each attempt because it’s not hitting the Z limit and keeps grinding it.
I used Build 582 to Send Configuration Data (newer build didn’t seem to have this button) and still can’t get past Z initialization. I’ve taken the sides off and checked all the bolts and everything’s tight.
Testing the limit switch in the 618 Motion build’s UI does show the switches reporting presses. I can’t seem to find a solution.
Okay, totally fixed up now – as that video (comments) suggested, I had screwed the MDF down with the wrong screws (round head instead of flat) unwittingly which made contact with the metal frame, preventing Y from moving entirely. That failed but appeared that it was X not working (I just noticed that Y starts moving right at that moment so it was the true failure.)
