Hi.
That’s great news 
There’s the most likely at least a partial culprit for Your issues.
And a piece of information that is useful in Your profile.
I haven’t tried mine yet because I don’t have the extended bed enclosure built yet, but the xTool bed extension has been causing some troubles lately.
Different issues than Yours, but I for one wouldn’t rule out that those issues could be related somehow.
Could just as well be a whole new issue though, it’s xTool we are talking about after all.
As Yours work now, it’s possible that xTool has included the fix onto the firmware and/or the lbdev. file.
Regards,
Sam
