If you want to print fast, I recommend looking at V2
NEW: step file for V1 (May 2023 version) added
MAY 2023 UPDATE TO V1
Reinforced arms
M3x4mm heatset insert supported - if you use heatset inserts use the round holes on the face that the screws enter, otherwise put the usual hex nuts on the nut traps on the other side
full set is now indeed a full set(thanks @Ixian_67258)
tighter grip with arm and bed carrier
Simple, budget(-ish) and effective triple Z implementation for the ender 5 that doesn't block access to the front of the printer like pretty much every dual Z mod
I've done a speedboatrace on it with a corexy motion system @20000mm/s^2 here and the bed barely shakes (unlike my first speedboatrace attempt with just super struts)
What to print:
I recommend printing full_set.stl since it has all the parts on one bed and orientated correctly to avoid supports. It is located in May 2023 latest version/full_set.stl
There are also files for individual parts if you need just one of the parts
Features:
Independent control of all 3 lead screws - if you add a stepper expansion board you can do Z tilt adjust(klipper recommended)
Very rigid if you use a denser infill
Uses original Ender 5 bed carrier and rear Z system
You probably have most of the parts lying around anyways
Bill of materials:
2x NEMA 17 steppers - I used these and were the right length
2x T8*4 350mm lead screws and nuts
2x 8mm 370mm linear rods
8x M3*8mm socket head screws
2x 5mm to 8mm couplers
2x LM8UU linear bearings
10x M4*8mm socket head screws
10x M4 drop in T nuts
Stepper motor extension cables - length depends on where your electronics are
