Would anyone have valid Remora NVEM v5 config samples available anywhere? I do not have an EC500. I do not have an EC300. I have an NVEM v5 and so far no examples will work at all. Attempting to use the hal and ini files from github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic do not seem to work as they all seem to be for the EC500. Any attempt  to use the config samples from github.com/scottalford75/Remora-NVEM results in compounding errors and will not run axis at all. Perhaps all I need to do is edit the EC500 hal and ini files? Is there any guide that will instruct me as to WHAT in those files I need to edit to get it to work? When I run the axis ec500 config and toggle the Estop and power on I can see the activity lights on the ethernet port start blinking so I know there is at least an attempt to communicate with the controller, but I am pretty sure that most else is different in the configs between the EC units and the NVEM units.

Honestly at this point I am sure I have an acute case of information overload and have wiped out and reinstalled remora more than a few times.

Thank you for presenting other approaches to the subject. It allows me to better understand the general principle of operation of various concepts and HAL structures
I will test your suggestions (it will take me some time) and I will definitely describe it on the forum so that it will be helpful for other and so that they do not bother you with nonsense like me hehe )

Is there any free cadcam software for mill ?
I know NativeCAM and librecad-freecad for cad something else ?

Thank you very much Hakan, I have attached the result as a file 

 

The ethercat master doesn't have the right contact with the network interface.
Do "sudo service ethercat restart" and show here the lines from "sudo dmesg" from this restart, some 30 lines or so, check time.

Hi guys

I couldn't resist and bought a new board, this time I opted for a 3-axis EC500,
it has LEDs that indicate the I/O status, I think it's more complete.

I tested it with Mach3 to make sure it was working well, given the previous ones,
and it worked on all three axes.

When loading the firmware, it got to 29% and timed out and everything froze,
the DAP wasn't receiving signals.
I reread page 115 of the thread that talks about how to unlock and after having
bridged BOOT_MO and 3V3 I managed to delete and write the new firmware!!

Now all 6 axes work.

Thanks again to Scott and to whoever made all this possible.

Hi
I connected to a small laser gantry structure the EC500 with Remora
and a small demo video .
I have to say it works great!!!
Thanks!

THANKS!!! WORKS!

Now i understand, because they are isolated you need to connect the common pin to a GND reference point to the voltage that will be applied to the input 1-11 pins. I connected everything as you said and it works flawlessly. !!!!

This feels like a bigger achievement than getting my Master's degree haha.

The isolated inputs will not work as expected unless you connect the
input common (TB3 pin 12)

For sinking inputs (pullup to a positive voltage to activate), input common should be
connected to  GND/power common. If you are using 5V from the 7I96S, this is the
stepgen connector GND.

And yes if you use a 24V supply and sinking inputs, the 7I96S input common would
connect to the 24V supply common (negative)
 

Thank you very much.

I don't understand how this is different from what I am trying. here is the setup:

Switch NC to 5V from one of the pins (would it be okay to plug it in the stepper motor DC 24 power supply?)

Switch C to PIN 1 TB3.

IN this case I am missing the TB3 common pin - will it work if I connect it to the GND from the MESA where I am getting the 5V will it work? It is not working as it is right now.

Eitherway if you say it is safe I will connect the DC power supply 24V to the limit switch NC then C switch to TB3 pin and I can connect the Common TB12 pin to the Power supply DC GND.

If you use NC limit switch contacts and sinking inputs, wiring would be:

7I96S input common (TB3 pin 12) = GND (24V common)

+24V --> Limit-Switch C --> Limit-Switch NC --> 7I96S Input (TB3 pin 1 through 11)

In hal, the input must be inverted.

You can use 5V instead of 24V but it's not as reliable long term with mechanical switches

 

The following results:
- ip a returns the result that the adapter is running without errors:
enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP

- the permissions are also correct:
crwxrwxrwx 1 root root 238, 0  3. Mai 16:22 /dev/EtherCAT0

nevertheless the link is DOWN and I cannot start a test configuration

OK, that's opposite of what the 7I77 enables do (they are on when enabled)

Probably easiest is to add a external relay, driven by a field I/O output
and wire the NC relay contacts to all drive enables.
 

hey i am having some trouble wiring switches to the board here is what I tried:
I am using pnc conf
I read that the inputs are opticallyisolated so I can put a lot of voltage on the input pins (haven't tried yet only 5v)

the mechanical switchers have NC NO and C

I tried connecting NC to 5V and V to pin1 doesn't stop during homing
inverting just began the turn on with an error about the switch limit


I tried connecting NC to GND and V to pin1 doesn't stop during homing
inverting just began the turn on with an error about the switch limit

I tried connecting NO to 5V and V to pin1 doesn't stop during homing
inverting just began the turn on with an error about the switch limit

I tried connecting NO to GNFand V to pin1 doesn't stop during homing
inverting just began the turn on with an error about the switch limit

FInally i tried attaching NC to 5V, NO to GND and C to pin one and it worked but then the mesa card would get restarted ( apparently its shorting something when i hold the button too long


i saw some other people connecting NC to 24V and then to pin 1, but it should work with 5V as well and it doesn't. i tried pin 0 as well in case the pin was not working. 

i am getting the 5V and gnd from the STEP 3 pins. 

I am very interested what exactly is it that I am doing wrong. 

THanks
 

I created a diagram so that the offset value can be visually confirmed.

Yes, the machine is on, it jogs and the icon for homing is grayed out, when I get to my shop next week I will upload pictures. Absolutely appreciate you guys are really awesome. Super helpful and responsive! Much appreciated! If there’s anyone in this forum that is for hire, let’s talk.
