README.md

Vcore3 500^3

Intro

Configure and document a Vcore3 from RatRig with a Duet 3 6HC. The Vcore3 is a core xy 3d printer with a kinematic bed on 3 axis. The purpose of this repo is not to have a 1 fit all solution but the solution that works for my use case, I've tryed to provide all the hardware components and their setup, this may not suit your case. If you have a suggestion please consider opening a pull request. In the other hand it may help you setup your printer in a fast way, use at your own risk. Parts of the g code are not mine and were extracted from the ratrig config, duet github repos, and other sources (references on the links and external sources bellow).

Pay special attention to the stepper direction and stepper step/angle, these are not standard.

Git structure

V1 branch

  • Tries to keep compatibility with the default RR HW
  • Can be used as a default config

Master

  • It uses my personal config
  • It supports or will support newer/better hw, pwm fans, camera, thermal camera, etc
  • Better HW monitoring
  • Better automation

Steppers

Replaced x y 0.9º nema 17 for 1.8º LDO steppers, these old 2.5A per phase at 3.1v. Pay attention to currents and number of steps while configuring your printer.

Note: the stepper except the pancake one have the following specs:

Duet 3 6HC - Pins

IO

Used IO pin headers

  • io_0 - display
  • io_1 - y endstop
  • io_2 - x endstop
  • io_3 - Duet filament sensor
  • io_7 - bltouch

Stepper motors

All steppers are 0.9º

  • z left - driver2 - motion backwards (looking from the back of the printer)
  • z rear - driver1 - motion backwards
  • z right - driver1 - motion backwards
  • top right motor - driver3 - Y - motion forwards (looking from the back of the printer)
  • top left motor - driver4 - X - motion forwards
  • extruder motor - driver5 - motion forwards

Outputs

Heating elements (24v)

Heating elements in use:

  • out1 - SSR Bed
  • out2 - Hotend
Fans (24v)

Fans in use:

  • out4 - layer fan
  • out7 - hotend fan
Lighting
  • out8 - dc ssr operated leds

Temperature probes

Thermal probes in use:

  • temp0 - Bed thermistor
  • temp1 - Hotend thermistor

TODO

  • Add printing tracking camera

  • All macros are untested until stated otherwise (some are cloned from duet repos, others are mine), list of tested macros:

    • Lighting (all)
    • Preheat (all)
    • PID tuning Bed && HotEnd
    • Preheat PLA / ASA / PETG
    • Musical Tunes
    • Diagnostics/Disallow unhomed moves
    • Diagnostics/E steps calibration

Electronics backplate

I've also set a exectronics backplate (to be a cut of alluminium or polycarbonate up to 4mm), you may find it in thingiverse.com.
