I have a PowerSpec 3d Pro (Flashforge Creator Pro) and I'm having a horrid time adjusting my extruders, they are not level, and I understand the procedure for leveling, however, when I remove the set screws, the nozzles will not go up and down without turning them back and forth. It seems others can just nudge their extruders in place to go up or down. I'm wondering if others have had this issue and how they solved it.
