I got the firmware to run on stm bluepill. It only works with the clones that have 128kb memory, so you need to check that beforehand. I dont know if I can get to small enough to add sd card, but it works with the static config. I think I wrote over the usb bootloader though, so i will have to look into it. spi pin out is PA7/6/5/4/3

Ok the good news is I can get the firmware down to 116kb, so thats cool

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

Will depend on the type of output the encoder has, there should be a blurb in the box...or just throw up the model number and I can advise.

I think Old Mate is referring to the potoo board the MCU board is on.what is a bluepill remora shield

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

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

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.
