LinuxCNC-PC - Remora - OrangePi3 LTS - BTT SKR V1.4 Turbo

Category: Computers and Hardware

Go for it!
Despite Tuxcnc being right about the time and effort, humanity would not reach very far if it did not try stuff that may or may not be "standard".

If you have a 7I96, it can support up to 4 MPG encoders directly on the isolated inputs
with the right firmware ( 7i96_inmd.bin )

Hello everyone,I am new to LinuxCNC and would like some help with the installation process.I would appreciate guidance on:
  • The recommended Linux distribution for the latest version of LinuxCNC.
  • The installation steps for a fresh system.
  • Any prerequisites or dependencies I should install.
  • Common installation issues and how to resolve them.
  • Whether there are any official installation guides or tutorials for beginners.
Thank you for your assistance!

LinuxCNC-PC - Remora - OrangePi3 LTS - BTT SKR V1.4 Turbo

Category: Computers and Hardware

Well I’m always up for a challenge!
I reckon I can get this running as reliable as ever.
This was the best solution I could think of, as usb isn’t an option. Then realised, this has the potential of actually being quicker and more reliable than usb.

LinuxCNC-PC - Remora - OrangePi3 LTS - BTT SKR V1.4 Turbo

Category: Computers and Hardware

I have all the hardware, so buying supported/prebuilt hardware, is more expensive…
 

You're wrong.
You will waste a lot of time (that's also money) and you will reach a wall that you can neither get around nor jump over.
Short time ago I have removed four Remora EC500 from working machines, because this project has no future.
I spent many hours with this hardware and not solving some troubles (stupid 3,3V differential outputs not fitting motor drivers and not working spindle encoder).
I bought four Chinese 7i92, because it was cheaper and better, and now I have many time for other projects...

Yes I believe you are.
PC → Ethernet → Orange Pi → SPI → SKR

Again, read. Through my repo. It explains everything! In depth!

LinuxCNC-PC - Remora - OrangePi3 LTS - BTT SKR V1.4 Turbo

Category: Computers and Hardware

Am I understanding correctly, the Pi in this project exists purely for bridging ethernet udp <-> spi?
I am always interested in new ideas. Sometimes new ideas hatch breakthroughs.

Actually this is cheaper. I already have it running on GRBLHal, and I fancied a challenge.

Plus, this could open up a lot of extra windows and doors!

Category: Computers and Hardware

Nonsense.
This will be not cheaper and not better than chinese 7i92 + cncshield (~60 US dollars on Aliexpress).
I have small table milling machine controlled by ESP32 + W5500 + cncshield (hal2udp project) - it is cheapest solution and work well.

Yeah I am wokring on trying to find a wiring diagram or more details on the wiring and electronic side to be able to do that. Again, I know a guy on here did something similar, but his was a bit different than mine. 

This was his post he had: www.forum.linuxcnc.org/27-driver-boards/...cix-5x10-cnc?start=0 maybe the auther,  randypetersen  could help out?

You can not test servos and other hardware from a virtual box, but you can from a live session when booting from USB.

Gantry oxyfuel / plasma type machine from scratch

Category: General LinuxCNC Questions

The idea of starting with and virtual environment is just because i still have no dedicated machine, and to not to loose time learning and testing various GUIs to see how I will be doing the workflow of the production of the pieces , configurations and other stuff which is not really related on 
testing servos and other hardware things. This will permit me to get more comfortable with the software.

LinuxCNC-PC - Remora - OrangePi3 LTS - BTT SKR V1.4 Turbo

Category: Computers and Hardware

Ive started a new project.

I want to control a mini 3 axis cnc ive built, with LinuxCNC. The problem I hit, i have a BTT SKR v1.4 Turbo board, a PC and an OrangePi3 LTS SBC board.

The Plan:
Install LinuxCNC Debian on the PC. Install and configure Remora on the PC. Connect to the OrangePi3 LTS through ethernet connection. This in turn, will be connected to the BTT SKR v1.4 Turbo board via SPI. The SKR board has the latest LPC1769 supported Remora firmware installed on it.

Follow this repo for my progress. Feel free to collaborate!
