Printed parts: * extruder body, * extruder idler * extruder large gear * extruder small gear

note that you should screw both hotedn screws simultaneously.. if too much resistance, unscrew and file a bit more.

align the gears.. if neccesary use M3x10 screws instead and add some M3 washers

4x Bolt - #6-32 0.5“ 1xBolt - #6-32 0.75” 1x Bolt - #6-32 1“ (isn't that too short? It hold only on half of the nut) 9x Bolt - #6-32 1.5” 15x nut #6-32 4x #6 washer

5xM3x8mm 1x M3 nut printed pully, motor

endstop !!!!

LC parts 150, 130, 154, 120,121 (131 not necessary now, but it's easy from this step on) 3x Bolt - #6-32 0.5“ 1x Bolt - #6-32 0.75” 1x Bolt - #6-32 1.5“ 1x #6 washer 5x nut #6-32

note about square and hexnuts note the position of the hole on the side, tighten the 1/2in bolt after the 1.25in bolt is in place (don't tighten the 1.25in bolt yet)

preassembled bridge, preassembled xcarriage stage1 LC parts : 2x 152,2x 153 8x nut #6-32 8x boltBolt - #6-32 1.5“

6x nut #6-32

8x boltBolt - #6-32 0.5” 2x boltBolt - #6-32 0.75“ (Brook uses 0.5” in his video, but he mentions (and I recommend) that it's quite short and you can use 0.75“, and washer instead) 2x #6 washer (optional, see above)

extruder assembly bridge with x-carriage base from stage 2

note the length of the bolts for bolting extruder, note the length of the bolts used to both parts of carriage note the removing (or adding after assembled) of the extruder motor discuss the possible ways of assembly

!!! z-endstop

4x spacer 4x 1” bolt (or alternatively M3x<something + nut>)

z-rods holes are quite firm.. you need to wiggle and turn the rods while inserting
