Xol Toolhead Bill of Materials (BOM)

Read ALL of the sections below to understand your hardware requirements, there's some bits here that aren't on a standard Voron build BOM. The chances are that something was missed, but if you have a good mix of M2, M2.5 and M3 hardware you'll probably still end up with a working printer.

Carriage

Required Hardware

Qty	Item	Notes
5	M3 Heatset Insert	Standard Voron spec: 5mm Outer Diameter x 4mm Length
6*	M3 x 6 BHCS	Only 4 required if using MGN9H carriage 2x MGN12H carriage rear 2x Carriage front 2x probe module
8*	M3 x 8 SHCS	only 4 required if using MGN12H carriage 4x Join carriage front to carriage rear 4x MGN9H carriage mounting
4*	M3 Hex Nut	Only 2 required if using MGN9H carriage 4x Carriage rear
2*	M3 x 26 Pin	Belt mounting system for 6mm belts 24mm, 25mm and 26mm pins have all been tested. 26mm is the strongest if pushing limits
2*	M3 x 30 Pin	Belt mounting system for 9mm belts

Optional Hardware

Qty	Item	Notes
2	M3 Heatset Insert	If not using m2.5 heatsets for toolhead feet attachment

Probe Hardware

Follow probe instructions for required hardware. Where possible, self tapping screws have been replaced with heatset hardware, usually M2.

* If using Voron Design TAP RC8+ it is recommended to replace the two M3 x 50 SHCS with M3 x 50 BHCS to improve build plate clearance.

Toolhead

6	M2 x 12 SHCS	Part cooling fan and duct mounting
2	M2 x 8 SHCS	Part cooling fan and duct mounting - top rear screws

Fans

ℹ️ Understand your electronics and voltages
Do you have the correct voltage at your toolhead or will you need a converter?
If using the recommended parts you need 5v, 12v and 24v at the toolhead.

Qty	Fan Type	Recommended Fan	Notes
1	2510 Axial Fan Hotend Fan	Delta Electronics 5v ASB02505SHA-AY6B	Purchase Link This fan is highly recommended in heated chambers No other 2510 fan comes close to the performance of this fan.
2	4010 Blower Fan Part Cooling Fans	Delta Electronics BFB0412HHA-A (12V) Purchase Link BFB0405HHA-A (5V) Purchase Link	24v GDStime fans are fine and many have used them successfully. The Deltas, however, have better durability in heated chambers and always hit their performance claims. Its not uncommon for other fan manufacturers to overstate performance, GDStime included.

Additional notes: Delta's 5V and 12V variants provide the same airflow, pick whichever suits your setup better. If you only have 24V available, you can use a 24V-12V buck converter like K78L12-500R3, or run an additional wire in your umbilical for 12v+.

Optional Hardware

Qty	Item	Notes
1	M3 Heatset Insert	Sherpa-Mini K-plate attachment
1	M3 Heatset Insert	DFA Custom bottom
2	M3 Heatset Insert	*If not using M2.5 hardware for HE Mount "feet"
1	M2 Heatset Insert	3.5mm Outer Diameter x 4mm Length X End stop
1	M2 x 10 SHCS	X End stop
1	3 LED Neopixel harness	If using LED ducts and faceplate Can be self-made for best wire fit, or re-use StealthBurner harness with a short extension to reach toolhead board.
