      I am working on tuning an IDEX. I am at the point where I am working on the offset values between my T0 and T1. I started a print to test my Z offset and when it calls for T1, the T0 is doing all the moves while the T1 is doing the extruding. I dove through my config and everything looks fine which means I just don't know what I'm looking for. Maybe its in the free/post files...I dunno. Any guidance would be greatly appreciated. TYIA!

        you have the 2nd tool offset configured in the X axis not U axis. also the mapping for the Axis is missing, you have to map the X axis to be the U axis in line 117

        like this (taken from the docs)

        M563 P1 D1 H2 X3 F2 ; tool 1 uses extruder 1 and heater 2 and maps X to U, use fan 2 as the print cooling fan
G10 P1 Y0 U0 Z0 S0 R0 ; set tool 1 offsets and temperatures

        X3 means that X is mapped to the #3 Axis

          @Superbrain8 Thank you very much. I looked over that a few times and still missed it. All I had to do was add the X3 and its fixed. I shouldn't have missed that. Thank you again!
