Galileo driven Z-Drives

The source components are from the greatproject and design ofJaredC01 (see Voron Discord)

Mind that these components are by design of the author a TIGHT FITSome pressing in of the bearings is expected and IMHO intended.I used a long exagonal key driver (M10) to press them in by my body weight..

You can reach out in Voron Discord i'moc_geek V2.1064 V2.1820

This is goint to be my second Voron 2.4 buildand il will be equipped with Galileo Z Gearboxes and Galileo Extruder (and few other mods :-) )

I made some chages to his design (was tailored for Voron 2.2 in ~ 2020)

• Fixed the hole height of M5x40 screw to grab 5mm on the M5 post insert nut
• The Mount has a larger center hole (now ID is 8.6mm) to allow the bearing removal and avoid D shaft rubbing plastic
• Reduced the 4xM3 holes in the Mount to ID 3.4 mm (from 4.2) for a snug alignment to the Gearbox shelve
• The Mount (aka Foot) is now 10 mm taller to better suite a V2.4 build bottom height (it does not change the belts lenght)
• Stepper Spacer has now a hook (with M5x20 BH) to the inner frame extrusion so stepper Motor weight does not load on Gearbox. A hole for the M3 pass through screw has been added to the spacer for mounting the Gearbox shelve
• Added skirts for V2.4 300mm including a rotating gear (pressure) mounted on the D-Shaft protruding out of Mount front (~ 3mm)

I developed all those changes inFusion 360TheCAD file is too large to store herei uploaded it on Google Drive (lates update 11st July 2021)Z Drive f3z archive

Z Gearbox BOMQuantity is for ONE (1) Gearbox

• 10T metal Spur Gear x1 - <https://www.aliexpress.com/item/4000299898525.html>
• 5x4mm Heat inserts x8 (Voron BOM)
• 60mm Long 5mm OD D-shaft (Voron BOM)
• 16T "Prusa Stile" Pulley with Base H=6mm (thinner than POWGE) x1 - e.g. <https://www.amazon.it/gp/product/B07T5CYBJW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1>
• 1.0mm shim M5 washers x2 (or 0.5mm if you wanna play finer)
• F695 2RS Bearing x4 (Carrier and Gearbox)
• F625 2RS Bearing x1 (Mount)
• M3x12mm SHCS screws x4 (to close the gear Shelves)
• M5x16mm BHCS screws x3 (gears to carrier)
• M3x18mm SHCS screws x4 (connect to the Stepper)
• M3x20mm SHCS screws x4 (connect Mount to gear Front Housing)

Mounting a Z-Drive to the frame requires:

• M5x40mm SHCS screw x1 (Mount part to Frame from where the rubber foot is)
• M5x16mm BHCS screws x2 (Mount part bottom two holes to Frame)
• M5x20mm BHCS screws x1 (Accent Spacer to Frame)

See in theAssembly folder there are some notes on how i did put these things together :)

These are the assembled GearBoxes

I modified the spacer so that it hooks onto the frame and sustains the Stepper weight.Also it sists in the center of mass of the assemblyThis is reccomended works very well

I amended the Mount (foot) to be 10mm taller and better suited to the Voron 2.4 (the change does not change the belt lenghts)

This is a list of what i ended up installing in this build :)

Frame and Panels:

• 4mm thick polycarbonate panels (including the bottom deck to view through the electronics)
• Doors with hinges
• Handles 2x on top and 2x at bottom sides (it's 50Kg this thing...)

Control Electronics and cabling

• Duet Mini 5+ Wifi
• Duet 2+ expansion (to reach 7 drivers)
• Prepared for an additional Duet 5+ (not yet installed for ERCF MMU unit - future) via FD-CAN bus
• Duet Tool Board 1LC (v1.1 with included accelerometer) mounted on the tool head side and connected via FD-CAN bus
• Heluflon FEP wires (AWG 18, 20, 24)
• MDPC-X sleeve (used out of the chains)
• Wago 221 connectors
• Chamber temp / humidity sensor (DHT21)
• Ambient temp thermistor
• Various cable management brackets (made in Fusion360) and cables routing guide out of the cables hole in the back

Mechanics and movement:

• OMC Steppers-online motors
• 1.8* on Z axis (4)
• 0.9* on X-Y axis (2)
• LDO pancake for Galileo Clockwork Extruder
• Galileo gear-boxes for Z movement (required redesign of the entire skirts)
• Galileo Clockwork (Coupler Edition) for Extruder
• MGN-12 single rail on X axis
• AB-BN 30 tool body with 5015 work cooling fan
• Hall effect end stops for X/Y
• MGC5 spherical Z joints
• Klicky probe (instead of the inductive Z sensor) for bed leveling and final Z0 setting
• Pin mod on all bearings / idlers (5mm pins replace M5 screws - requires specific printed parts)

Air Filtering

• Nevermore Micro recirculating active carbon filter (dual 5015 fan located under the heated bed; also serves as quick chamber heat distribution in the pre-print phase)

Lights:

• WS2811 (aka neopixel) addressable LED strips with controllable brightness and color for each LED on each strip
• 15 LEDs on front, 18 LEDs each side top

Others:

• Purge bucket with scrub
• Align stands for the steel flex plate (two embedded in the Purge bucket body)
