# Vcore3 500^3
|
|
## Intro
|
|
Configure and document a [Vcore3 from RatRig](https://www.ratrig.com/3d-printing-cnc/3d-printer-kits/all-3d-printer-kits/v-core3configurable.html) with a Duet 3 6HC. The Vcore3 is a [core xy 3d printer](https://www.reprap.org/wiki/CoreXY) 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
|
|
|
|

|
|
- - Lighting (all)
|
|
- - Preheat (all)
|
|
- - PID tuning Bed && HotEnd
|
|
- - Preheat PLA / ASA / PETG
|
|
- - Musical Tunes
|
|
- - Diagnostics/Disallow unhomed moves
|
|

## 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](https://www.thingiverse.com/thing:4792093).
