The Franken-10 extends the existing X-rail, where the hotends travel on both sides, so there is additional space for the inactive extruder to park. This is made to keep the build-volume as big as possible.
- Single-Extrusion: 300x300x400mm
- Dual-Extrusion: 280x300x400mm
- Duplicate-Mode: 150x300x400mm (your model can only use the half width)
You can still print in single extrusion mode, with your existing slicer and profiles. If you want to print with two filaments, there are this options:
- Single-Extrusion
- Dual-Extrusion (two colors or two filament-types)
- Duplicate-Mode (the same model printed at the same time)
Of course, 24V would heat up the extruder(s) and the bed a little bit quicker, but this would lead to additional costs (PSU and 24V-Heated Bed). If you want to do this upgrade, you can do this. The SKR PRO-Board supports Voltages from 12V - 24V without modifications.
There are no programming skills needed. Although, you need to completely disassemble your control-box and soldier a few cables.
Also you need to print the parts yourself on your printer.
You don't need to drill anything in your existing CR-10 Frame or something like this.
The Firmware is based on Marlin 2.0.x with Thermal Runaway Protection enabled.
You can use any slicer that supports two extruders. Franken-10 comes with preconfigured PrusaSlicer-Profiles, which I recommend.
