Remora - ethernet NVEM / EC300 / EC500 cnc board

Sorry I would like to try your code out but I have got confused by the long forum thread and discussions about mixed boards and processors and I have two simple questions

1. I have one of the EC300 STM32F2 boards with a PWM chip. From your posts the HEX file for the STM32F2 NVEM board should work on it as is?

2. In the post dated 20 Nov you mention "All IO on the NVEM and EC300 is working." but the repository at github.com/scottalford75/Remora-NVEM no new commits for a couple of months - am I looking at the right repository?

Thanks for the good work!

Hi, yes a very long thread moving from topic to topic. Not so easy to digest.

1. If your EC300 has the F2 chip then yes the NVEM bin file is what you need. Note that it has not been tested on the old EC300.

2. There is a new repo for the RT1052 based boards. github.com/scottalford75/Remora-RT1052

I managed to spend some time with the EC300 and the Remora firmware and was able to get the basics working. This was once I figured out the HAL input numbers were the "data bit" numbers in the uploaded config file and not the EC300 text labels!

I also had to add:

loadrt lowpass count=1
loadrt abs count=1
addf scale.0 servo-thread
addf lowpass.0 servo-thread
addf abs.0 servo-thread
setp scale.0.gain 0.1
net spindle-cmd-rpm spindle.0.speed-out => scale.0.in
net spindle-cmd-rpm-abs scale.0.out => abs.0.in
net spindle-speed-DAC abs.0.out => remora.SP. 0

to the HAL file to get the spindle to output 0-10V for a 0-1000RPM range.

The only thing lacking is a spindle encoder module to handle more than just an index pulse.

Hello  scotta I
I bought EC500 from China market to use Mach3,They said my EC500 is version 5. As a saw there are some changed in board layout. (see the pictures). This such thing not working with Home and limit switch, another big issue makes me can live with it is Probe command "G31" not working! I dont got any support from that company! 
Very interesting witch your working, Does has any firmware can run LinuxCNC on this board now?  I go through page to page and get some Infor that till now only work with older version of ec500 using STM32 processor, And RT1052 is on develop?
Thank you for your great work 
Best regard.

Hi, yes your board should be supported by the work to port Remora to the RT1052. I'll have an EC500 for testing in a week or so. Welcome to LinuxCNC!

Just created the dev branch.

Found this when down the rabbit hole of getting Remora SKR running on a cheap fan less Linux PC SoC
There's a ton of potential with this rt1052, I'm thinking servos..

— Four FlexPWMs
– Up to 8 individual PWM channels for each
– 16-bit resolution PWM suitable for Motor Control applications
— Four Quadrature Encoder/Decoders

Your quick start instructions for getting the toolchain setup are stellar. Thank you so much!
Cannot wait for my CIMSS device to arrive.
