Open Printer Settings - Extruder and configure your settings for dual extrusion:.In Repetier Host, open Printer Settings - Printer and set the manual extrusion and retraction speed:.Install Repetier Host with CuraEngine Slicer.Please input all values EXACTLY as shown in the images below, unless otherwise highlighted in RED text.
These instructions outline the steps for configuring Repetier Host and Cura for dual extrusion with the Prometheus System.You can download the Smoothieware Configuration here.īack to top Host/Slicer Setup 1) Repetier Host - Cura We do not currently have step-by-step instructions for configuring Smoothieware firmware for the Prometheus System, but you can make the necessary changes by referencing an MKS Base Smoothieware configuration used with the Prometheus System.Set 500 steps/mm (1/16 microstepping) or 1000 steps/mm (1/32 microstepping) for the extruder steps, 60 mm/s for the X-axis jerk, and 15 mm/s for the E-jerk:.Enable "cold" extruder moves and lengthy extrusion:.Set EXT1_TEMPSENSOR_PIN equal to EXT0_TEMPSENSOR_PIN.If you need to reassemble the hot end just unscrew the heat sink to avoid removing the thermistor or heater cartridge. NOTE: The thermistor is delicate so you should not attempt to remove the thermistor after heating the hot end.Re-upload the firmware to your electronics board.Copy the final values for Kp, Ki, and Kd from the PID Autotune and enter them into your firmware:.Connect to your printer and run M303 PID Autotune:.Upload the updated firmware to your electronics board.Set 500 steps/mm (1/16 microstepping) or 1000 steps/mm (1/32 microstepping) for the extruder steps, 60 mm/s for the X-axis jerk, and 15 mm/s for the E-jerk:.Marlin - Configuration.h: Disable the following lines of code using //:.Enable "cold" extruder moves and lengthy extrusion:.Configure your firmware for using a Single Nozzle (new Marlin feature):.Configure your firmware for Dual Extrusion:.Configure your firmware for the Semitec 104-GT2 Thermistor :.NOTE: If you are using Marlin firmware then you MUST use the Marlin RC BugFix version. The following steps outline the firmware configuration for Marlin and Repetier Firmware: A simple approach would be to buy some bungee cords and wrap one end around the ProStruder and attach the other end to the top of your printer frame. While we suggest mounting the ProStruders in a "flying" config for delta printers, we cannot provide detailed instructions for creating a flying extruder setup because every printer is different.Below is a picture of the Prometheus System mounted on one of our custom delta printers with flying extruders and short bowden tubes:.For delta printers, mounting the ProStruders in a "flying" configuration with short bowden tubes will decrease hysteresis and increase the quality of your prints. Secure the ProStruders to the frame of your printer and mount the Prometheus V2 Hot End to your carriage/end effector.If the above motor wiring does not work for you, try BLACK = 1A, GREEN = 2A, BLUE = 2B, RED = 1B. If the stepper motors turn in the wrong direction, you can easily reverse the direction by reversing the wiring: BLUE = 2B, RED = 2A, GREEN = 1A, BLACK = 1B. The wiring will be BLACK = 2B, GREEN = 2A, RED = 1A, BLUE = 1B. Plug the 4-Pin Stepper Motor Cable from each extruder into the pins for extruder 1 (E0 on RAMPS 1.4) and extruder 2 (E1 on RAMPS 1.4) on your controller board.This Heater MUST run on the rated voltage! Wire the Cartridge Heater and Thermistor to your controller board.Please ensure that these fans are always on! DO NOT connect the Cooling Fan to your controller board "Fan" output as this output is used to control fans for cooling the printed part. This will ensure that the Cooling Fans runs continuously at full speed to provide optimal cooling for the hot end and extruders. Wire the 25mm hot end Cooling Fan and the (2) 40mm extruder Cooling Fans directly to your power supply, red wire = (+), black wire = (-).Please check back regularly to see the most recent version.
