Remember, a box offset is small in up distance, about 3/8 of an inch, so you need to barely get the conduit to bend. Once you have the first bend done, just roll the conduit over 180 degrees, scoot the bender shoe back a couple inches, and put the same type of bend . This guide explains how to bend a box with a press brake, which tooling to use, correct bend sequence, common mistakes to avoid, and how modern CNC press brakes improve precision and repeatability.
