RailCore II - ZL Option

thingiverse

Optional Printed Parts to upgrade a RailCore II to a RailCore IIZL The full RailCore II project is here: https://www.thingiverse.com/thing:2407174 The ZL option implements 3 point automatic bed leveling - physically leveling the bed using your Z probe and 3 independent Z steppers. This option requires a Duet Controller and a Duex2 or Duex5 expansion. Details on the bed leveling as implemented are here: https://www.duet3d.com/wiki/Bed_levelling_using_multiple_independent_Z_motors Using 3 independent Z steppers under the bed, each driving its own leadscrew, we've implemented 3 fully independent Z towers. These allow the controller to use a Z probe near each of the towers, and automatically level the bed. Parts needed for the ZL option (and parts not needed from the standard RailCore II Build) are listed in the BOM Here: https://docs.google.com/spreadsheets/d/1KvlSNYHE20HYjQlURdH50Pn_V7t8TfuNNLnhcvI4Nos/edit?usp=sharing Fusion 360 CAD model for the ZL version is available here: http://a360.co/2DoeHFu <b>PLEASE NOTE: This is early in testing, and may change</b>
