Working in Progress !!! Feel free to help if you want FlyingBear Ghost 4S Dual Extruder DIY Instructions : 00. This is not an official trademark guide, everything you do is at your own risk. You may understand what you are doing. The mainboard is a FlyingBear version of the Makerbase "MKS Robin Nano" (same hardware and pinout). You can find a lot of information on their GitHub page. I'm working on: 1. The 3D model of print head, 2. BLTouch leveling implement, 3. A prettier interface, 4. Wifi function (unstable for now). Read the "HowToDo.txt" and "HowToWire.jpg" first I took "nntuan" sources pictures for the interface: https://www.thingiverse.com/thing:3799741 0. You will need some spare cables and parts before starting: A 3D printed in ABS or PETG dual hotend PrintHead. You can design yourself and share! Print it before starting! 1x "2-pin JST male-male" 20cm cable. 1x "2-pin JST male-female" 150cm cable. (for the printing cooling fan) 1x "4-pin JST-XH female" connector 1x TMC2208 Stepper Driver 1x Extruder Motor dual extruder hotend fan extender large black sleeve small black sleeve printed part 3D printed parts Assembly Steps: 1.

Put the card in the printer port. e. Plug in the printer and power it on! f. The screen should display the firmware upgrading progression, if not unplug immediately and verify the card files g. When update is finished move the print head and bed to the center of axis and verify it moves in the right directions 5. EVERYTHING IS DONE! ENJOY! 6. If you want to downgrade to single extruder and stock firmware a. Replug the cables as indicated in the original manual b. Put the stock firmware on SD card and upload it
