+## Sourcing Guide
+- See "VORON 1.6.2" at [sourcing guides](https://vorondesign.com/sourcing_guide?model=VL) page (1.6.2 is same as Legacy according to nemgrea)
+
+
+## Assembly
+- Voron Legacy [Brief assembly Guide](https://forum.vorondesign.com/threads/brief-assembly-guide.176/) by Sanity Agathion, a Voron forum admininstrator.
+- Unofficial assembly video series: [Voron Legacy](https://www.youtube.com/playlist?list=PLm2OH_myqt7a_PT0lViufZZBrC22PzAQH) by [Fugatech 3D Printing](https://www.youtube.com/@Fugatech3DPrinting) on YouTube
+  - Uses drop-in not slide-in T-nuts, so if using slide-in ones, take care to insert them before locking them out via assembly. See unofficial assembly manual below for image and description of where to insert them.
+- [Voron Legacy Unofficial Manual by Poikilos](https://docs.google.com/document/d/1mR3VX70ok1uY0DY2WcfInHhRfALJT7SdbVQVug27Xh0/edit?usp=sharing)
+  (WIP)
+
+### Known issues
+(Differences mentioned are from actual measurements of motors, making belts centered on gearheads' teeth, etc. Belts are in blend file in Poikilos' Voron Legacy folder on Google Drive, along with these fixes)
+- (CAD folder) Make motor shaft of A & B motors 0.152 mm longer so they are 24mm from the screw surface like motors in the 1.6.2 BOM
+- Move A (right) gearhead (20T pulley) down by 2.35 so it is 3.45 less than end of motor shaft
+- Move B (left) gearhead (20T pulley) up by 0.10217 so it sticks out 1.25mm more than end of motor shaft
+- Add (1) M3X40 socket head screw to each side of rear of X Carriage (2 total)
+  - Add (2) threaded inserts for them.
+  - 1.25mm of the threads are underutilized, so make socket head holes that much deeper.
+- Inductive Probe object is unnamed (Fixed in FreeCAD file).

+  - Alternate leadscrew block for anti-backlash POM nut (2 shank holes, spaced further apart).
+    - Fits ["Ender 3 V2 Z axis T8 POM Anti Backlash Spring Loaded Nut Elimination Gap Compatible with Voron 2.4 Ender3 pro 3D Printer 8mm Acme Threaded Rod"](https://www.amazon.com/dp/B088FPNVVF?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1) from POLISI3D Store on Amazon.
+      - Be aware, these are consumable (will eventually tear apart and lose the threads)! Regular brass ones are recommended in the sourcing guide.
+  - Alternate 206mm bed screw spacing parts (for reusing bed from A8 clone such as A3S)

+      - No 320 motors exist though, so use a regular stepper motor, flexible coupling (See unofficial sourcing guide below), and ~300mm lead screws such from A8 clone such as A3S.
