Steve's Extruder and Hot End
Current Hot End Photos
This hot end design is used on Rostock MAX by SeeMeCNC. It is useful for adapting to many other printers too.
History
Development began October, 2011. The Steves Extruder was created to be tough, versatile, and provide consistent extrusion rates. Plastic injection molded parts were initially ABS, then changed to Nylon for more durability. During SeeMeCNC's first H-1 3D printer indiegogo campaign in 2011, contributors gave live feedback as PartDaddy designed live on ustream. Many contributors gave input, like Dave S of WA state, regarding o-ring springs, and another contributor asked if it could do both 1.75mm and 3mm filaments. So the drive rollers are turned with both size grooves.
PartDaddy preferred both drive rollers were driven. The gear train was chosen because it would possible for someone to print. A NEMA 11 through NEMA 17 stepper will work with this design. Four 3mm x 10mmL pan head machine screws are recommended.
