Mein Fabrikator druckt jetzt schon eine ganze Weile recht zuverlässig mit dem E3D V6 Hotend als Bowdenumbau. Etwas überdimensioniert, hat er damals ein Smoothieboard erhalten um die drucke ein wenig feiner und sicherer gegenüber dem Ramps zu machen, jedoch ist das Lautstärkelevel durch die A4988 sehr nervig. Daher die Idee das final nochmal umzubauen und das herumliegende Chimera-hotend mit zwei Titan Extrudern einer Bestimmung zuzuführen.
Als Board kommt wahrscheinlich ein Megatronics, bestückt mit DRV8825 aus der demontierten MPCNC, zum Einsatz.
Die neue Frontplatte sollte die Hitze des Chimera gut abführen und sieht auch recht wertig aus trotz des leicht stumpfen aber scheinbar unzerstörbaren Sorotec Fräsers. ( Versehentlich 5mm doc Vollnut bei 900mm/min für gut 200mm)

Designing and Building a Dual-head 3D Printer
I had the opportunity to try out at least 5 different printers. All of them had sifgnificant backdraws like missing heatbed, price and noise. They all did there job anyway and my Fabrikator is working pretty much „fire and forget“ all the time. Nevertheless I´m tempted to create my own printer just for the sake of adding it to my collection of valuable experiences.
I came up with T-Bot first iteration closely related to prusa´s I3 framewise. I didn´t liked the Z leadscrews standing out that much and too far away from the linear slides so the second version focused on making this a little more aerodynamic.
I am aiming for a precise as possible head and bed positioning mechanics with dual extrusion the bowden way. I have good experience with bowden so I don´t see any significant disadvantages at the moment.
The second version with the new z and x mechanics.
There are E3D V6 mounted on the gantry at the moment but it should be stable enough for light milling operations.
The frame is designed with 16mm MDF in mind but I probably change to a different material (not OSB). Thats why I have to redesign most of the frame parts as the new material is somewhat thinner.
I already have most of the electronic components in mind. The first prototype might be powered by components I have laying around but the finished version is meant to be state of the art 🙂
Watching Thomas Sanladerer´s channel really helped me out making decisions at some points in the design process so thank you for your effort in making great videos, if you ever read this.
