Ender 5 Dual Z - Version 2

thingiverse

Update 6-10-2020 --- Added Ender 5 Dual Z - Rod Bracket - Upper v2 - Adjustable v6.stl. This adjustable bracket was used to keep the rod-to-rod spacing the same due to my frame not being square, causing binding at the top. This can only be used on the top; using it on the bottom will throw off rod-to-leadscrew alignment. --- Update Done --- This is Version 2 of this mod: https://www.thingiverse.com/thing:3784970 This mod requires replacing the top left and right extrusion with 2040 to allow space to mount the top rod brackets, also giving the added benefit of raising the extruder up 20mm for easier viewing and more Z travel. Be mindful of belt routing when mounting the rod brackets; a linear rail mod might be able to be used instead of replacing the extrusion. Version 2 was created to allow the bed to be centered and rotated. Centering the bed will allow for a larger bed in the future, while rotating the bed allows ease of unloading/loading and viewing the print. Please note that the inside version was not tested by me due to very little room for the leadscrew because of the stock metal bracket; however, a new motor mount was created for the inside version, but the stock motor mounting plates can also be used. If someone tests the inside version I would appreciate some feedback on it. This mod was made to stabilize the bed, addressing side-to-side and up/down movement common with a cantilever bed. Bed supports help but do not cure the problem; I had waviness in my walls as well as bed sag with heavy prints until this mod was added. You will need leg spacers if you plan on using a regular size stepper motor; if you have a pancake like the stock one, the spacers are not needed. I moved my electronics enclosure to free up room at the bottom; the Z carriage might hit your electronics enclosure if not moved. If it does, I think you will only lose about 5-10mm of Z travel but this is not verified.
