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

Hi scotta

So can I reverse the signal for the rest of the hardware? Limit switches are also NC type. As well as tool sensor and 3d sensor. If so, how? I checked the outputs and they live. well thank you

Hi, unfortunately no. The board you show is a USB board, not the Ethernet version which the Remora firmware supports.

Hopefully soon. As per my earlier post, I'm working on the ability to upload a custom configuration file into the board that will allow you to do exactly what you asked.

Any idea which hardware versions of the board should work?
I've seen 1.1, 2 and 2.1 during my search.
