Remora - Rpi Software Stepping Using External Microcontroller via SPI

Well I finally got vtk working and installed for rpi 64bit.
Now I have a mostly working probe basic ui!
Some of the conversational gcode pages are blank.

Just a few more odds and ends and my mill will have a much better control scheme.

Scotta, i would love to buy one and try, do you know if it works on the turbo board?

Is there a disc img i could get for my rpi4...? please and thank you. I've had no luck with 64bit so far

I used the supplied 64bit LinuxCNC image for rPi and added Remora and it's working on my 3D printer( Creality Ender 3 ).

I got the 64bit image from here:
It is based on Linux raspberrypi 5.10.25-rt35-v8 with PREEMPT_RT and LinuxCNC 2.9.0~pre0
drive.google.com/file/d/1WPtmXieDDmWi0Aj...z03/view?usp=sharing

For Linux users, I have a script which handles extracting the image to the uSD, setting up a custom hostname, enabling SSH, sets locale to us pacific and will create ssh authentication creds.

From here, get script-zipdd, script-config and wpa_supplicant and put them in your Downloads directory. Edit the script-zipdd file and change the word "donkey", on two lines, to "lcnc" so it finds the lcnc image in the zip file and run script-zipdd from the Downloads directory.
github.com/dlarue/Lubuntu-Donkey

I have a USB adapter for the uSD so I added the sdb option for alternate devices other than mmcblk0 SD card readers. KNOW YOUR DEVICE NAME!

./script-zipdd ./lcnc_2.9.0pre0_rt64a.zip linuxcnc-ender3 sdb

After it finished, I added Remora to the uSD before booting the rPi but you can do it later if you want. Here's what I did:

- mount rootfs
cd /media/userID/rootfs/home/pi
git clone github.com/scottalford75/LinuxCNC-3D-Printing
git clone github.com/scottalford75/Remora
cd Remora
git checkout TMC_testing
git pull
cd ..
cp -a Remora/LinuxCNC/ConfigSamples/ender3 linuxcnc/configs/

- mount controller(SKR v1.4) uSD card
cp Remora/Firmware/FirmwareBin/LPC1769/firmware.bin /media/userID/uSD-Device-Name/
cp Remora/Firmware/ConfigSamples/SKRv14_TMC2209/config.txt /media/userID/uSD-Device-Name/
sudo umount /media/userID/uSD-Device-Name/
- insert uSD into the controller and power on

- boot the rPi and run sudo raspi-config and expand the filesystem and reboot. Once logged into the rPi, install the required linuxCNC modules:
cd ~/LinuxCNC-3D-Printing/PIDcontroller/
sudo halcompile --install PIDcontroller.c
cd ~/Remora/LinuxCNC/Components/Remora/
sudo halcompile --install remora.c

- run LinuxCNC

Yes, working with the turbo version. The picture is with my SKR v1.4 turbo.

Happy to send one of the prototype boards. PM me your details.

Ive looked all over how to PM

Hi, sorry. Feel free to email me. My email address is my github username @ gmail.com

Well lets give it a go.... i just got the 1.4 turbo

Great to hear. Please let me know where the documentation is lacking so that I can help where needed.
