Take care that if you are on a multiplayer server, the issue itself may be an anticheat plugin seeing the fast placing/breaking of blocks by a buildcraft machine as cheating and that is why it wont work.

If that is the case ask other players on the server if they have had the same issue with a filler, quarry etc and speak to the server admin.
