So I run the new firmware bin and hal. I didn't move on. Sensors do the same.I can't turn their signal to true / false

Hi Domi,

The work I'm currently getting close to finishing will allow for configuring inverting inputs on the NVEM board itself. The upload-config.py file uploads a config.txt file to the board. It's very close to working. Until then you will need to use HAL on the LinuxCNC side to invert the pin.

Use the NOT component to invert the input. (not tested)

eg
loadrt remora-eth
loadrt not count=3

addf not.1 servo-thread
addf not.2 servo-thread
addf not.3 servo-thread

net X-min-inv remora.input.6 => not.1.in
net X-min not.1.out => joint.0.home-sw-in joint.0.neg-lim-sw-in

etc

How can I test the outputs on the relay so far? I also threw a probe screen v2 but estop is broken. But the question of Estop control is not possible.Isn't it the one we have the STOP input involved and ESTOP the MPG output?

You can test the outputs by manually setting them using the HAL configuration window / utility. In the Test HAL command input box

setp remora.output.0 1 or 0

For the e-stop you will need to use the estop_latch component.

Ok, so I've got the e-stop config working. To make it simpler I have updated the firmware to invert the STOP input as this is a NC switch. Please update to the latest firmware.

I've also made a specific config for ethernet-nvem to be specific for this board.

github.com/scottalford75/Remora/tree/fea...gSamples/remora-nvem

The e-stop HAL is below and I've tested on the bench.
Code:
# load the real-time components     loadrt remora-eth     loadrt estop_latch     loadrt and2 # estop and comms enable and feedback     net nvem-estop             <= estop-latch.0.fault-in             <= remora.input.4     net user-enable-in         <= and2.0.out                         => iocontrol.0.emc-enable-in     net remora-status        <= remora.status                    => and2.0.in0     net estop-status        <= estop-latch.0.ok-out                => and2.0.in1          net user-enable-out        <= iocontrol.0.user-enable-out        => remora.enable     net user-enable-out                                             => estop-latch.0.ok-in     net user-request-enable <= iocontrol.0.user-request-enable    => remora.reset     net user-request-enable
