Hey, I recently had this issue and found the best way to level my extruders. There are basically 2 steps. 1. Level the hotend/nozzle attachment to the aluminum block using calipers. Measure from the tip of the nozzle to the top flat surface of the aluminum block making sure to leave room for the top of the hotend to just touch the plastic on the extruder or just below it. Try your best to make sure both nozzles are level to the thousandths. Do this by making sure that you are contacting the same points on each side. 2. Level the block to the carriage. Attach the extruder/hotend assembly to the carriage and tighten the bolts as you would normally. Use the slicer to home the nozzles, then move the nozzles over the middle of the bed. If your platform is level this will be easier. If not level it the best you can. Doing this will allow you to use a piece of paper to find out which nozzle is higer or lower from the bed. When you figure that out, remove the hotend from the carriage and use small strips of kapton tape around the threaded hole on the aluminum block where it mounts to the carriage. Make sure that you have the same ammount of layers on both sides of the hole and apply 5-6 layers. Reattach the extruder and check that the nozzle is raised. Add or remove layers until its perfect.
