Overview

Features

  • Eco edition - insulated heatbed for 30%-60% lower energy consumption while printing with heated bed
  • Upgraded to 24V control system
  • Silent stepper drivers - uses TMC2208 in legacy mode instead of A4988
  • 500W heatbed for 1 minute bed heatup time
  • Added built-in GFCI electrical safety breaker as a standard feature
  • Still uses the Titan Aero extruder with 3 mm nozzle
  • Auto bed leveling with babystepping correction

Fabrication

Code

  • Endstop_reversing was reversed on X and Y compared to pre v19.02 versions, where we now use default after going to plain endstop, and not the endstop breakout board. Optimizing bed coordinates and bed probing in Marlin. Marlin v19.04 can be used with v19.02 and should be the 8" bed standard from now on.
  • Mintemp reduced to 1C from 5C - to allow near freezing performance. Kept above 0, as 0 means disconnected. Thus, thermistor lockout is still present
  • Changed 408 to 425 steps per mm for Titan Aero - #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 80, 425 }
  • Change probe location from 20 to -20 - #define X_PROBE_OFFSET_FROM_EXTRUDER -20
  • Changed X and Y bed limits to 8" - #define Y_MAX_POS 204 //changed from 175
    1. define LEFT_PROBE_BED_POSITION 40 // changed from 20
    2. define BACK_PROBE_BED_POSITION 160 //changed from 150. All together ~40 mm off each edge
