Ender 5 Dual Z 2020 (Bed Support)

Last crawled date: 4 years, 1 month ago

Hello, Thanks for stopping by to look at my project. This is for the Ender 5 and it will move the Z to the sides rather than front to back. You can use your existing plate or buy a new thicker plate and drill/tap M4 holes in the bottom of the plate like I did. Up to you. This mod also allows for expansion of the bed mount screws which happens during heating. (Keep the warping to a minimum.) You can just cut your own extrusions and use your own corners or open build corners like I did.
In addition to this, I raised the Z height by buying (2) 2040 extrusions thus raising the XY top portion of the machine. I moved the Y motor (short extrusion mount) to the top of the frame to match the additional 20mm frame height.
For this project I will assume:
You will purchase or already have lead screws and anti-backlash nuts from Zyltech.
(Important, the mounts currently are only designed for these backlash nuts which are much larger in diameter than the stock nuts or the ones you normally buy. I may at some point design an optional mount for the stock nuts.)
You will purchase or already have an extra motor or 2 new motors to drive your dual Z.
You will purchase or already have 2 extra 10LMUU bearings and 4 new 10MM X ??? Shafts. 4 10MM Rod supports.
You will purchase or already have screws and T-Nuts of your choice.
You will purchase or already have extrusions. I selected Misumi part numbers which are cut to length. You can buy or use any extrusions you like in addition to using printed corners or open build corners.
You have knowledge on how to change your e-steps, add another z motor if needed through your firmware.
You will need to align and test the movement of your set up before you "home all" or you could have one motor bind and that's not a good start. So put it together, measure for consistency and move a mm at a time all the down and all the way up to adjust for any issues.
You will need to print, prior to tearing down your printer:
2 Each T8_Lead Screw Mounts
4 Each 10LMUU_Mounts
2 Each Bedsupports_Right
2 Each Bedsupports_Left

If you buy the wrong thing, please don't blame me. This is why I called them "suggested" sources. You may want to reuse parts or use a different pitch or motor. Use your thinker don't be a stinker. ;) Questions? Do ask please. I'll help as much as I can.
Special thanks, credits, considerations:
@rgrugan : Without his support, this project wouldn't have been posted. His solid E5 ED3V6 mount really made this printer precise. https://www.thingiverse.com/thing:3946974
@snakep : His linear rail mod is awesome! https://www.thingiverse.com/thing:3782865
Good Luck! :)
