Update 09.01.2020: I updated the lead screw nut hole to accept a wider range of lead-screw nuts, before the diameter was 22.0mm and now in V2 its 22.6mm. I also added some minor tweaks overall. (check out the gif on the bottom of the page) If you like it, don't forget to leave a TIP for a cold or warm beverage: https://www.paypal.me/akoswonerth This is one of my upgrades after I installed the E3D Hemera Extruder/Hotend. The slightly heavier Hotend needed a little more support on the right side so i thought about upgrading to a second Z Axis. Inspired by CR83D's Dual Z: https://www.thingiverse.com/thing:3742027 I made my own version from scratch for the Geeetech printers: What you'll need: 1x Stepper Motor 1x Stepper Driver 1x Motor Cable 1x T8 Lead Screw and nut (Pitch 2mm, 4 start, 8mm lead) (400 steps/mm) 1x 8x5 Coupler (I use this one on all my printers: https://www.thingiverse.com/thing:1264447 ) For the second Z-screw mount: 1x M4x50mm - alternative: 1x M4x55mm threaded rod + M4 Lock Nut 2x M5x40mm For mounting the stepper Motor 4x M3x16 screws 2x M3 T Nuts Printed Parts: 1x Dual Z Back Plate - Lead Screw Mount 2x Small Spacer 1x Big Spacer 1x Stepper Motor Mount ( https://www.thingiverse.com/thing:2752080 ) I wired the second Z-Motor to the free drivers on my GT2560_V3 board, but if you don't have any free driver (A10T or A20T) you can still wire the second motor in Serial or Parallel to the first Z-Motor
