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

Build Checklist

  1. Prior to first turn-on, verify that all axes move smoothly through their full range of motion, without interference with structure, bolts, wiring, or endstops.
  2. Before first turn-on, make sure you removed the D1 diode for powering the Arduino. This is the only thing that can fry your arduino.
  3. Upload Marlin v19.04 if not uploaded yet. Do you have Marlin v19.04? Make sure it's not v19.02 or earlier
  4. Power up arduino on USB only
  5. Power up arduino via 12V connection after verifying that USB connection works.
  6. Verify that the capacitors under the stepper drivers are rated for 35V.
  7. Check 24V and 12V coming from power supply/ Verify that the top of the power plug (closest to screw-down terminals) is 12V, and 24V for the bottom section.
  8. Go to Cura, load an object, and in control screen command line - use M119 to check endstop status to make sure that they are not triggered. Check 3 endstops for proper triggering. They should be OPEN in the Cura window when not engaged, and TRIGGERED when engaged. Note the Code Change Log for changes when simpler endstops are used
  9. Check for motion of X, Y, and Z using Cura.
  10. Check heater and heatbed using Cura.
  11. Once that is all good, adjust endstop height so bottom of blue probe is at the flat part of the nozzle above the conical part of the nozzle
  12. You're ready for first print.

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
