BLV 3-Point bed levelling

thingiverse

These are the bed mounts for my 3-point levelling system/kinematics for the BLV. These have been designed to work with the bed I designed, which can be found here: https://www.thingiverse.com/thing:3875857 I have made a jig for easier placement of the aluminium extrusions that hold the rails. I have made this so on side with 1 z-screw, it is to be located 205mm from the front extrusion. Opposite side front extrusion for rail is to be placed 80mm from front extrusion (corner piece) and back rail extrusion is to be placed 230mm away from the front rail extrusion. Any questions, please feel to ask....I will try to provide answrs with diagrams but can't guarantee how quickly I will respond. Add this line in your config.g for correct positioning: M671 X-15:365:365 Y175:50:300 S15 Please note, I have provided my bed.g file but I have set the the probe points with offsets for my probe, which will likely be different to yours. As such you will likely need to adjust the x and y positions for each of the three test probe locations accordingly (usually I'd recommend inline with the leadscrew on the Y-axis, and about 10mm in from edge of the bed on the X-axis. Extra items needed (assuming you have a BLV MGN Cube and wish to change to 3-point levelling for the bed): 1x 2040 extrusion of length matching your existing two, 1x mgn12 linear rail matching length of existing two, 1x lead screw, matching length and pitch of existing two, 1x stepper motor matching your choice for the existing two, 1x nut for leadscrew, 4x M3 nylock nuts, 4x M3 x ~8mm to mount to mgn12 carriage, 4x M3 x 20mm screws to mount leadscrew nut, pack of 10 M3 x8 screws, similar amount of M3 t-nuts to mount the linear rail. 6x M5 x8 screws 6x M5 t-nuts ...Possibly a duex2/5 if multiple extrusion also desired (for Duet2 Wifi/ethernet setups).
