so for some reason, i cant seam to get the nozzles on my dual aligned with each other. the one on the right is maybe about 1mm or so lower than the left and the screws wont tighten any more to raise it. i have removed the heat sink from the carriage to make sure that there wasnt any blockages inside and double checked the heating block to make sure that the screw that buts up against the nozzle is level with the top, which it is. i even used digital calipers to measure the distance between both heater blocks and their nozzles and they were the same, but just looking at it i can see that the right heater block is slightly lower than the left. so besides loosening and retightening the left extruder to see if it will sit lower (both of the tighening grub screws protrude farther from this one as it is), can anyone think of anything else i can try or have had any experience with this issue?
