I think he was asking more for this:
First mods:
Glass/Tile bed - Easy level- Improves bed level, reduces lifting on ABS, improved stick, easy to clean and more rugged than kapton tape.
Enclosure - Easy level - Improved layer adhesion, protects machine from dust, improved stick.
Calibrations - Easy - Improved extrusion flow, improved circles, better quality, better stick.
Intermediate mods:
Replace Z rod - intermediate - Reduces banding, increased accuracy.
Replace stepper driver for extruder - intermediate - Sanguino board only. Improved extrusion, reduces moire effect.
GCode extruder fan - intermediate - improves PLA lifting, improves overhang printing, improves bridging
Replace extruder jigsaw parts - easier nozzle removal, required for upgrading hotend.
Replace bed heater - faster heatup times.
Advanced mods:
Replace X/Y carriage: Improves quality (better movement), improved printing at higher speeds.
Upgrade hotend for higher temperatures: Improved printing of Nylon, improved printing at higher speeds.
LCD SD card or Rasp pi: Print without PC attached.
This is just an example and I could be wrong about what would be easy or hard and weight of the benefits, but I believe this is what he is asking for. There is a great lack of summarizing/consolidating this information. Especially on this forum (and the wikis are either outdated or incomplete). There really needs to be a place where this information is compiled. That can be the sticky, and each individual mod can be unstickied. At least, thats the way I see most popular forums are structured.
