Electronics
Stepper Motors
The Jason Mendel uses, including the extruder, 5 NEMA17 stepper motors. Two of these motors, the Z axis motors, are connected in series to the same stepper driver of the electronics. The extruder stepper motor needs a minimum holding torque of 40Ncm (0.4Nm). More information can be found on the Stepper Motor page.
Controller Electronics
Ramps v1.4 is recommended for the Jason Mendel. Required features: 4 stepper drivers, 2 thermistor input and 2 heater output for the extruder. For more information see Ramps
Extruder
The extruder used is a standard Greg's Geared Extruder with an E3D Direct Feed Hotend. The gears for the extruder should be made of nylon.
Heated Bed
The Jason Mendel includes a Heated Bed which allows for the use of materials such as ABS which can experience significant warping if printing on a cold platform.
Materials
The Jason Mendel is capable of printing ABS, PLA and Nylon. It is recommended to apply a layer of Blue M3 tape to the bed prior to printing.
