RailCore II - ZL Option

thingiverse

Optional Printed Parts to Upgrade a RailCore II to a RailCore IIZL The full RailCore II project can be found here: https://www.thingiverse.com/thing:2407174 The ZL option features 3 point automatic bed leveling, which uses your Z probe and 3 independent Z steppers to physically level the bed. This option requires a Duet Controller and a Duex2 or Duex5 expansion. For details on the bed leveling as implemented, visit 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 have created 3 fully independent Z towers. These allow the controller to use a Z probe near each of the towers and automatically level the bed. The parts needed for the ZL option and those not required from the standard RailCore II Build are listed in the BOM Here: https://docs.google.com/spreadsheets/d/1KvlSNYHE20HYjQlURdH50Pn_V7t8TfuNNLnhcvI4Nos/edit?usp=sharing A Fusion 360 CAD model for the ZL version is available here: http://a360.co/2DoeHFu Note that this is an early testing phase and may change.
