2	Motion Components
3		MGN12H linear rail - 200mm	3	NEW FOR V4: V4 uses MGN12H for the X axis.	Amazon - Usongshine		RobotDigg		For all linear rails, endevour to order two carriages per rail. This is cheap insurance incase one of your carriages is not moving smoothly.
4		MGN9H linear rail - 200mm	2	Ensure to source as high a quality as feesibly possible. RobotDigg 440C advised.	Amazon - Usongshine		RobotDigg		Remove all transport oil from rails using a solvent (IPA, brake cleaner, etc.) and inject a lubricant into the raceways to lubricate. EP1/NLGI1 ideal.
5		GATES-LL-2GT 6mm timing belt	4M	Main timing belt for CoreXY motion system. 5M + 5x pulley bundle available from Mellow.	Filastruder		Mellow Store	TriangleLab	GATES highly recommended. Poor quality belts may stretch and snap over time.
6		2GT pulley (5mm bore, 6mm belt, 20 teeth)	3	Used for A/B drive motors. One used for Z endstop.	Filastruder		Mellow Store
7		2GT toothed idler (5mm bore, 6mm belt, 20 teeth)	2	Used in X/Y joints. E3D/Mellow style ideal due to a 7mm width to allow for minor travel.	Filastruder		Mellow Store		All idlers and bearings should be sandwiched by a shim on each side. Non-E3D/Mellow style requires 1mm of shim on each side.
8		F695-2RS bearing	20	Used in X/Y joints, idlers and A/B drive for allowing smooth motion of the belt. 2RS have rubber seals to prevent the bearings getting contaminated. ZZ has less friction but no protection from contaminants. If in doubt, go for 2ZZ.	Amazon		Mellow Store
9		TR8x4 200 mm leadscrew	1	Leadscrew for Z drive. May substitute TR8x2	Filastruder - will need to cut				You may substituted a Nema17 with integrated 250mm leadscrew for this, the coupler and the Z Stepper
10		TR8x4 POM nut	1	Allows leadscrew to drive the carriage. May substitute TR8x2, and or brass nut	Filastruder
11		5x8mm Plum coupler	1	Accounts for axial deviation to minimise Z banding. Not required if using a motor with an integrated leadscrew.	Filastruder		TriangleLab
12		Motor mount plate	1	OPTIONAL, replaces printed_parts - lead screw motor mount.stl and is stiffer	Zyltech		Funnsor	Amazon	Note, must use an M4x6 screw or M3x8 plus washers to get the right position of the leadscrew. Do Not use M5 to attach to the 2020. This also interferes with the bottom Z upright spacer, so you must use the optional corner brackets to secure the bottom of the z uprights
13	Frame - all frame components are listed as Misumi codes premachined for blind jonts and Black Extrusion. "HFSB5-2020-XXX" (black) or "HFS5-2020-XXX" (silver) should be used if using corner cubes or you wish to drill/tap yourself which will save a lot of money
14		HFSB5-2020-130-TPW	2	Z carriage.	Misumi				Tapped M5 both ends
15		HFSB5-2020-130-AH40-BH90	1	Z carriage. 5mm learance Hole 40mm from each end	Misumi				5mm holes horizontally 40mm from each end

22		HFSB5-2020-300-TPW-RCH-AH60	2	Back vertical extrusions.	Misumi				Tapped M5 both ends, 5mm hole horizontally 10mm from right end, 5mm hole horizontally 60mm from left end
23		21x15x12mm rubber foot	4	Feet for the printer. This specific size is needed to ensure skirts fit correctly.			LiKeWin Global Store	RobotDigg	The holes for these are 4mm. An M5x16 BHCS should be used to secure these to the frame, however be careful not to squash them.
24	Electronics and Control
25		Mainboard and drivers - SELF SOURCE	1	At least four driver ports required. Boards designed to be used with Enders can also be used (SKR E3 Mini, MKS Robin E3D, etc.).	Amazon		Makerbase Official Store	BIG TREE TECH Store	Double check that the board has the appropriate number of outputs for what you will be wiring in.
26		Raspberry Pi 3B+	1	Runs Klipper and your desired front-end. Memory capacity is not important, get whatever is cheapest. 3B+ is more than sufficient	Amazon				Raspberry Pi Pico is not compatible with Klipper. Pi Zero not recommended
27		IEC320 C14 inlet	1	Allows for AC connection to mains power, placed in upper right skirt.			EARU AUTO		AC components should be sourced from a reputable supplier.
28		FYSETC mini12864 LCD RGB TYPE B	1	Main LCD for Minima skirt. Fysetc have different colour options available which may be cheaper.	Amazon		FYSETC Official Store
29		Omron D2F-5L SPDT microswitch	3	Microswitches used for X/Y/Z homing. (KW10 may work as well)	Mouser			Digikey	OMRON recommended. Remove the lever or order D2F-5 for the Z switch
30		Meanwell LRS-200-24 PSU OR Meanwell LRS-350-24 PSU	1	Powers your printer. LRS-350-24 required for DC beds - Note, it has a noisy fan. Consider the fanless UHP-350-24	Mouser			Digikey	Source from a reputable supplier.
31		Meanwell RS-15-5 OR Meanwell RS-25-5 OR Buck converter	1	5V power for your Raspberry Pi. RS-25-5 has a higher power output for running external 5V devices such as LEDs. Buck converter can also be used, but not ideal.	Mouser			Digikey	AC components should be sourced from a reputable supplier.
32		Solid State Relay (3A) Cyrdom ED24C3 3A SSR	1	Required for controlling AC beds.	Mouser			Digikey	AC components should be sourced from a reputable supplier.

40		4010 24V axial fan	1	40x10mm cooling fan for the hotend's heatsink.	Mouser Delta 5V	Sunon (rattles)	Noctua (may not have enough blow)	Digikey 5V AFB0405HHA-A	24V is easier, but the best fans are Delta and they only come in 5v or 12v. The 5v we can pick off the Pi power supply
41		4010 24V radial "blower" fan	2	Part cooling fans for the V4 toolhead.	Mouser Delta 12V (2 in series)		GDStime	Digikey 12V (2 in series)	Double check the size and voltage prior to submitting order. for 12V fans, we connect them in series. This isn't idea because if one fan fails the other can as well. Not a big deal TBH
42	Extruder

47		120x120mm silicone heater mat	1	Bed heater should be < 130mm on a side to allow for proper mounting. AC or DC options available. 100w-200w advised. Earth the metal of the bed if using AC and add RTV around the edge to further secure it in place.			Keenovo	AliEpxress	Source from a reputable supplier.
