UPDATE: Version 2.0 August 19,2018
Long overdue update with some requested features. V2 Requires 1@30mm M3 screw and one M3 nut. Overall length now reduced to 42mm (Should fit the Ender 3). Standard height 13.5mm before extension. If you need increased height WJ_Lift_Ext_V2 will by default extend the height by 5mm. Most parts shouldn't need support, however part WJ_Wedge_V2 could have support added if needed.
Hex screw now can extend and retract the wedge (Counter-Clockwise raises, Clockwise Lowers). Please feel free to request changes to fit your need.
UPDATE: Version 1.5 August 16,2017
Made some minor modifications. I was finding that inserting the Jack was tight. So I have modified it to be another 2mm shorter in height and 5mm shorter in length.
Voila! No bed sag! My CR-10's build plate had sag in the middle. Just enough to throw off my bed leveling process.
I love the Jailcee W-Jack design but I needed a few modifications.
- Now uses M3 screw and nuts
- Total height of the jack reduced by 1.5mm
- Built in tracks for less possibility of side slip.
1@M3x30mm (shorter may work)
NOTE: Be very cautious of the electrical work in the center of the build plate. The wedge jack should fit forward of that area comfortably. Please see the build photo for placement.
ABS recommended due to heated bed temperatures. PETG may also work. An insulator between the heat bed and wedge jack may be appropriate.
Support for jack_wedge/WJ_Wedge_V2 may be needed. All other parts do no require any support.
