Hey brains trust!

I'm working on converting an NVEM v5 board (says IMXR_NVEM_V6   2022-08-11 on the silk screen) to use Remora. I managed to get the firmware uploaded to the board, thank you Scott for the great vid. The board uses RT1052 chip and I was able to make a donor STLink into a DAPLink and upload the firmware by compiling the latest Remora-RT1052-cpp from source. I could initially see it working by toggling the eStop in software and seeing the LED light up on the board so I know it was responding to LinuxCNC at first. I basically just followed the steps in the video. 

I got the static IP set up, did the Halcompile of the ethernet component, and then successfully uploaded an unmodified full_config.txt with the upload_config.py script, I managed to get past needing to install the TFTP package via PIP successfully as it wasn't included on my machine by default. This is where I'm now running into issues. After installing the config, LinuxCNC will no longer allow me to get the machine out of eStop, where it did before. Clicking the button does nothing and the LED on the board no longer toggles. It no longer lets me upload new configs, and pinging 10.10.10.10 now no longer responds (it did before I uploaded the config. This happened once already and re-flashing the chip got me back to being able to ping, get the machine out of eStop and upload new configs, none of which I can do anymore after uploading the config. The chip definitely isn't bricked as I can erase, reupload and step over code using the makeshift DAPLink as a debugger. 

I've tried wiring up a serial connector for the little port in the corner, but I'm not even sure that works to begin with - I've only seen Scott do it to an EC500 board so this potentially could help in troubleshooting. Seems I can read serial with a loopback and I know the wiring pinout, baud rate, comms settings etc from the pic on page 1 of this thread, none of that has output any data to any of the serial terminals I've tried on both of my machines.

I'm using the latest LinuxCNC version which I believe is now using Debian Bookworm which now uses NetworkManager so some of the instructions used in the video are now slightly different. I've fiddled with firewall and port settings but I'm not sure that's it because uploading and connecting works the first time just fine - port 69 is definitely open for SFTP.

Hope that's a good enough starting point for troubleshooting, let me know what other details I can provide to help troubleshoot this one? It's an odd one!

Hello, please excuse me for the delay in replying but I have been sick.

Yes, I managed to adjust my PID but not exactly, I still have small ocillations at certain positions of my rotating B-axis.

I saw that there is an Autotune. But impossible to find any practical documentation on this program which apparently makes a PID setting automatically???

I'm looking at how to program an Autotune in python. Sending commands and retrieving data, tracking errors is quite simple with "Import Linuxcnc".

the regylge of a PID is very tedious in length. If an automatic program exists, I'm a taker.

If anyone has any information I'm interested.

Thank you

Here's an explanation of "Latching Relays", which is what my schematic shows. I made up some PCBs to make the connections easier.

To late...

Yes improvement, not the same error now.
DId you disconnect and reconnect? Or just unplug the LAN cable on one side and plug it back again.
Now it seems the Mesa is off or disconnected, so:
-check the cable is inserted fully on both sides
-check Mesa for red lights (on power on it probably does come on shortly)
-check the Mesa 5V power supply, anything under 4.5V and anything over 5.3V roughly is reason to change the power supply
-use another cable ( i had new out of the box cables not work, kinks and stepping on them will make them useless, etc)

All fixed.

new connection setup. And hey presto we are working again.

Thanks Tommylight !!!! life saver

Changes made. no improvement

Yup, exactly, set to 10.10.10.10.
If you used the Network Manager to configure the PC, use it again to change it to 10.10.10.11 or 10.10.10.100 , save, disconnect and connect again.
If you edited the /etc/networks file, edit it there.

I would guess you changed the IP on the PC ....
That error is almost always due to PC having the IP set at 10.10.10.10 (or 192.168.1.121), set it to anything else for the last 2 (or 3) digits:
10.10.10.11 is fine
192.168.1.100 is fine
etc.
Edit:
check with
ip a

so working away and everything is going great, until. went to cut some plate today for the air scribe, turn everything on and then, she no connect. Worked fine a few days ago.

This is the error and i can't find a fix. Help

Hello.
I hope it's ok if i use this Thread for my questions. I've the same machine with same hardware (Turret, Encoder, Heldt&Rossi, Baumüller, Sinumerik etc.) and doing actually the retrofit with 7i97t and 7i84u.
My first question is... I need a enable signal for X and Z on the Heldt&Rossi amplifiers. (see picture)
I would connect PIN 19 to ENA0+ and PIN 10 to ENA0- on the 7i97t. Am I right that this would work?

I would do this a but differently
Let the mains power come in and use some DIN rail terminals from Ocean controls. They have some Bus bar connectors to join a few together so that are all common. you'll need some green earth terminals as well
Grab something like this industrial power point but seperate the two pieces and flush mount to your enclosuere
www.tropac.com.au/10-AMP-250V-3-Flat-Pin-Switched-Socket
Use the switch as your main power switch and the power point for your router. Put a household breaker on a Din rail for circuit protection
So now you need to switch your router from your 7i96s.
You could use a Jaycar SSR (you also need the heat sink on this page)
www.jaycar.com.au/solid-state-relay-4-32...a-switching/p/SY4084
Or you could use a contractor from tropac but make sure it will switch with 24v DC (some are AC), you may end up with a 3 phase one
www.tropac.com.au/search?keywords=contactor
Between your mains power and the 7i96s, use an EMI filter www.jaycar.com.au/240v-ac-emi-filter/p/MS4001. Then run the mains power to your 5v and 24v power and 36 volt power.
For your estop, Jaycar's one has  1 x NO and 1 x NC contactor. set it up so that the NO side switches 24v to an input and the NC side is on the mains power to your stepper motor supply and your router power point. The goal is that hitting estop will turn the router off and disable motion. We also want to send a signal back to the 7i96s so it knows estop has been pressed. the 7i96s will be powered on all the time.

Hope you have followed thaf!


 

Good afternoon Rod,

Thank you for your guidance and instructions. I am very overwhelmed... I am going to study the solutions suggested by tommylight and Rob ( unknown ), I feel comfortable because they are simpler than this. As my knowledge progresses, might be I can take on this solution.

My friends are all programmers, none of them know electronics. I can only ask questions online, and study using online resources. I find that it is hard for me to get through some issues.

Thank you and best regards,

...behai.
 

Installed the THCAD2 and to no ones surprise, it works!
No evidence of the deed though, sorry.

You are welcomed, always.
And thank you for sticking with us, you are here for a long time, looooong ...
