Bed Hoist for a 3D Printer - Final Version

thingiverse

A System for Z-Axis Movement with Hoist Action. For Example, for the D-Bot, Core XY etc. This is a Replacement of Version 3 of my "Bed Hoist for a 3D Printer (D-Bot, Core XY)", https://www.thingiverse.com/thing:2846764. Texts and So On Are Renewed. Version 2 on https://www.thingiverse.com/thing:3427719. In This Version the Wave from Version 2 Has Gone. I Call It Now "Final" Instead of "Version 3" Because It Is Essentially the Same, But Without That New Wave, Which Was Caused by Using the Wrong Hardware, Mostly the Bolts I Used to Function as Axes. In the "Notes" I Describe the Several Phases in Between. "Final" Does Not Mean That There Won't Be Any Changes, Preferably Improvements, Just That I Now Think That These Changes Would Not Be Necessary. Compared to Lead Screws, This System Is Much Simpler and Quieter. As Accurate Also, I Think. I Made This Thing So I Can Use It with My D-Bot_Linear_Z-Guide, https://www.thingiverse.com/thing:2779260, But It Is Independent of It. No Good Using It in a System with Wheels for the Z-Axis, Because Without the Support of the Lead Screws the Bed Angles So Much Downwards That This Cannot Be Compensated for With the Usual Bed Supports. Just Too Much Play in Those Wheel Systems, Whatever I Tried with 3 or 4 Wheels. So Be Warned. No Such Problem with the Linear Z-Guides. By the Way: These Guides Work So Much Better than the Original Wheels That I Only Would Need 1 Lead Screw, If I Would Want to Go with That. Only, as I Found Out Again When Comparing, the Bed Goes Down Without Power, Something the Worm Gear Is Good at Preventing, Among Other Things. Edit (March 28, 2020): At the Moment This Is Not True Any More, Since I Found a Motor/Leadscrew Combination of Robotdigg.com, Part No. 17HS3001-400N. They Claimed That the Quality of the Lead Screw Was Better than the Usual, So, Despite the Price I Tried It and I Like the Results. I Don't Have Any Commercial Interests with Them, So Please Inform Us If You Know of Lead Screws of Good Quality and Hopefully Better Prices, Preferably Without Motors, So One Can Experiment More Freely.
