Has anyone else experienced the same issue? Is there a fix? Maybe most importantly is anyone running on a similar set up without the issue?
Yes, Iam 
Actually it is compatible (IC² 1.15 and BC 1.8.1.1 with MCF 1.1.1) except crashing when trying to open an automated craftingtable of BC.
In your buildcraft\config folder in your SMP server change the line:
current.continuous=false
to
current.continuous=true
Remove your redstone pulser and just apply a single redstone torch to the quarry.
EDIT: Yay, first post
