Ender 4 Dual Extrusion Upgrade Guide

For all your Ender 4 Dual Extrusion upgrade needs.

######Note: It's a good idea to print all parts required for the upgrade before disassembling and rebuilding your printer.

Take care when upgrading, and double check your wiring before turning on the power.
I'm not responsible if you mess something up.

#####Parts I used for my upgrade
Motherboard
(https://www.amazon.com/BIQU-MKS-BASE-Plate-Controller-Printer/dp/B01FVTQQ2K/ref=sr_1_1?s=industrial&ie=UTF8&qid=1523203781&sr=1-1&keywords=MKS1.5)

#####Additional stepper
(https://www.amazon.com/Stepper-Motor-Bipolar-64oz-Printer/dp/B00PNEQI7W/ref=pd_sim_328_6?_encoding=UTF8&pd_rd_i=B00PNEQI7W&pd_rd_r=T8ATDMXGHN2V4R3MXWD9&pd_rd_w=ejACE&pd_rd_wg=ZElyI&psc=1&refRID=T8ATDMXGHN2V4R3MXWD9)
12.99$

#####Extruder
(https://www.amazon.com/Iverntech-Printer-Extruder-Aluminum-RepRap/dp/B0774JZ9N5/ref=sr_1_3?ie=UTF8&qid=1523207619&sr=8-3&keywords=MK8+extruder)
8.69$ (x2)
I purchased two and replaced the plastic one that came with the printer.

#####24v Heater
(Chimera kits come with 12v heater cartridges. These are not useful in this mod, as the Ender 4 supply is 24v.)
(https://www.amazon.com/BALITENSEN-Ceramic-Cartridge-Heater-Printer/dp/B078SQ4BPR/ref=sr_1_5?s=industrial&ie=UTF8&qid=1523207715&sr=1-5&keywords=24v+heater+cartridge&dpID=41KrrGy9eGL&preST=_SX342_QL70_&dpSrc=srch)
8.90$

######NOTE: Make sure you mark your 24v cartridges, or keep them sorted from 12v cartridges you will get from Chimera kits. Do not use a 12v cartridge on a 24v system. This will blow the cartridge, and likely start a fire.

#####Bowden Tube
(https://www.amazon.com/Teflon-2PC4-M6-Fittings-RepRap-Printer/dp/B07BT3F1PP/ref=sr_1_1_sspa?ie=UTF8&qid=1523204022&sr=8-1-spons&keywords=M6+bowden&psc=1)
6.28$

#####Cooling Fan
(https://www.amazon.com/SoundOriginal-50x50x15mm-Humidifier-Aromatherapy-Replacement/dp/B0755BY9RH/ref=sr_1_1?s=industrial&ie=UTF8&qid=1523205243&sr=1-1&keywords=soundoriginal+24v)
11.49$

#####Chimera Hotend
I used the WINSINN Chimera Kit, which isnt the least expensive, but it comes with a lot of other options for changing and rebuilding the hotend.
(https://www.amazon.com/WINSINN-Chimera-Hotend-Extruder-Full/dp/B075CK4JRN/ref=pd_rhf_gw_p_img_3?_encoding=UTF8&psc=1&refRID=S0SB0QXJF6XAF1CQSYYY)
49.98$

There are other options as far as chimera setups go, an E3D Chimera will fit in the mounts that you will need to print, there is also the cheapest chimera set I could find which is the Wangdd22 hotend on amazon

######Wangdd22 Chimera (purchase at your own risk)
(https://www.amazon.com/Wangdd22-Printer-Chimera-Extruder-Multi-Extrusion/dp/B076DDZMS7/ref=sr_1_7?srs=14414428011&ie=UTF8&qid=1523203197&sr=8-7&keywords=3d+printer+hotend) 35.99$

Total Upgrade Cost: 134.32$
