Hi
Is there a wiring diagram for a 600 ppr ABZ encoder to be used on a lathe. Sorry if this is a silly question!

I will be using a Nucleo64 STM32F446RE with a cnc shield v3

Awesome, here is the repo to get the firmware and linuxcnc component

github.com/cakeslob/Remora/tree/nucleo_static

This is the sample config for the highspeed encoder, it is not a complete lathe encoder config, I am still trying to do threading on the lathe. I have a new encoder but I still need to figure things out
github.com/cakeslob/Remora/blob/nucleo_s...q/remora-xyz.hal#L68

here is the documents
github.com/cakeslob/Remora-docs/blob/nuc...rdware/nucleo446.rst


Here is highspeed encoder pinout, it is referred to as QEI encoder, the other encoders are for lowspeed low res stepper encoders

what is a bluepill remora shield

I just fit the tiny cheap dev board on to an RPI shield thing so its a small setup. I thought it was neat.

Would this be a simple way to get Ethernet going, basically a Ethernet to SPI bridge ?
github.com/multigcs/LinuxCNC-RIO/tree/ma...PI-Bridge/WT32-ETH01

I have one in my bag of tricks and if kzali wants to test, or anyone in Sydney I can lend it out.

Cant do this anymore bye all wrote:

this will work with remora

Sweet !

but i think remora also supports W5500 modules (or similar) via SPI !?!?!

Hi Cornholio
Thanks for your offer! I already have WT32-ETH01 however I am new to LinuxCNC. I need to order an encoder, preferably from Aliexpress, trying to understand which one to get!
Your advise will be much appreciated.
I think private messaging is not working at the moment- would love to be in touch in Sydney to learn more.
