Make sure the playfield is leveled correctly. The hyper loop is sensitive to the PF pitch. Mine used to go endlessly until I held a flipper down, which I believe dropped the voltage slightly on the magnets to slow the loop. Now it will go around 2-3 times before dropping down the diverter ramp. My game shipped with the #3 and #4 accelerator magnet connectors flipped so they fired in the wrong order. Also, search for the thread that recommends adjusting the height of the ramp going into the Death Star. There are issues with it set too high and too low. Set just right and the first coil will pick the ball up each time. Basically, get the PF pitch and ramp height dialed in then go from there.
