In depth look at whats available for extruders, build types and installs.
lots of information and research to help guide you through the buy or build
process. The forum is building a hi-temp 3d printer that utilizes a pellet extruder built from plans and acquired parts.
This info from mahor design
Firmware configuration
Thermistor
#define TEMP_SENSOR_0 1
Steps per millimeter of the motor (1/16 recommended)
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 305}

The extruder from high temp is different, it has a different screw and barrel so this info is for referance only to establish a working setup, once established I will post
.137 to .187
Laminator Configuration
Filament settings
- Diameter = 1.75
- Extrusion multiplier = 1 *
* Depending on the type of plastic or pellet size, the flow may vary so it will be necessary to adjust it using the extrusion factor.
This is the progress i made with the build i made from the high temp printer plans
This was a BIG achievement
This is with a .4 head and the recommendations are using a .8
That will be my next attempt
also i am using some pellets that have not been conditioned, there are recommendations on handling the
the media, i think that will make a big difference also
