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
HW Config
- 1x Duet 3 6HC
Display
SBC
- 1x PI 4 2GB
Power supply
- 1x Mean well 400W 24v (RSP-500-24)
Steppers
