I have dual extruders setup in S3D and in the Astrobox control, selecting either nozzle one or two, the printer will only extrude from nozzle/extruder one. USB directly from S3D, the printer prints normally.
Why isn’t astrobox sending the input to the E1 slot. It sees the different temperatures that each hot end is at, but thinks there is only one motor/extruder.
