Yes, exactly.
Sorry for my lackluster explanation, i had a friend waiting for me back then.

Yes I checked spi status. There was no problem. I also added Blink module to check if firmware is flashed correctly and working. I too had octopus pro board. But I wanted tmc5160 drivers working so I bought skr3. I can see signals in hal meter, but in GUI I am getting No signals what ever

Don't know the answer to that question.

Linuxcnc is the execution of a number of halfiles by halcmd.
Check /usr/bin/linuxcnc for how it is done, it's a bash script.

You can execute the hal statements in the ec3a.hal file withMaybe you can puzzle something together.

So I attached a schematic with the pinouts in my previous post. I'm interested in learning what the process is for creating the firmware for a situation like mine where I do not have a daughter card. Do I load on of the provided files and modify the pinfile?

Swap the wires of one winding?

If your motor driver isn't powerful enough to power both motors together, just connect two drivers to the same input, connect each motor to a driver, with one of the windings of one motor reversed.

The drivers should be as identical as possible to ensure they perform the same.

OK.

The X and Y axes shall powered by 57VAC (all the drivers have an internal rectifier).

Should the Z axis have its own isolated winding, or should it remain powered from one half of the 57VAC supply?

The z axis does not move often, it uses less power than the other axes.

Have you tried to open the HAL configuration after the axis gui comes up and add in the pins you want to monitor. I would have the SPI status and enable pins there to check and see if your SPI connection is stable. I initially had a problem with the board I was using not getting a good flash and I had to use the BTT tool they talk about in their wiki to rewrite the original firmware before I could load the Remora firmware.bin to the root of the SD card and then it finally loaded the firmware correctly. I also ran into some issues with the firmware constantly resetting itself if I tried certain settings in my config.txt file. This is what I currently have in the conifg.txt file which may not be helpful since I'm running an Octopus v1.1 board.

Z400, Z420, Z600, and probably Z440, Z620, Z640, Z800, Z820 should all do just fine, those 3 at the start i have tested over 20 by now. Also HP 8300 SFF are pretty good, i have maybe 6 or 7 in daily use on machines.
Dell Optiplex series are also good, 7020, 9020 and 980, these i have in daily use, several of them for several years, but they do tend to heat much more than HP ones.

If you try to connect remotely via VNC after logging in with your username from the console, you'll get a gray screen. You'll need to log out from console.

Since the drives can handle it, i would stick with PCW's advice.
Do not worry much about drives getting hot, if you can hold your hand on the cooler they are still far from what they can handle, and just in case, if you touch them and a piece of your skin remains attached to them this would be when you start to worry.
50-60 degree Celsius to us humans seems like it is burning, 80 feels like it burns the soul, not the hand.

If I disconnect both cards (7i33 and 7i37) and type the command, it says nothing but OFF... 
Though Linux says connected

 

Hello, sorry for the late reply; I've been dealing with some personal matters.

I finally decided to go with the 7i97T and the 7i84U. I also bought the 7i74 and the 7i73 for future expansion. The first two boards alone are already overkill for my current needs, but I got the 7i74 so I can eventually add the 7i73 for a pendant controller with a screen.

I'm thinking of setting that up from the beginning since the PC won't be very accessible once everything is running. Having a handwheel for moving the axes and a few shortcuts or macros seems like a really good idea.

With just the first two boards, everything should be up and running. I expect that counting shipping and everything else, it should all arrive here in Argentina around the 15th of September.

So now, I'm starting to look for the PC to run it all. I saw the HP Z400 that @tommylight recommended for @andy. I can find it here for fairly cheap, refurbished. It comes with an Nvidia FX3800 for video output. Is that a good PC for this use case, or should I be looking for something else?

Thank you guys for all your help.

On updates, the status page becomes the splash page with important information for any changes made. It's the easiest way for us to make sure you are aware of and know to make those required changes with links of where to get additional information on them.

It is actually monumentally helpful for those who are running apt installations and who run apt update and have new releases get installed so they don't have issues and no idea why they have issues and where they are coming from.

On the same page is the error box on the right that reports actual errors in real time. If you have an issue that is affecting functionality, you will receive normal error pop up dialogs and the history of them will display in that box for trouble shooting.

I can see your perspective and will add a blurb regarding the intent of the splash page to avoid the issue for anyone in the future. You are the first to have an issue who reported it so while unfortunate, we appreciate you being it to our attention.

I can see remora input or joint cmd in HAL Meter. But nothing happnes in GUI. If I press limit switch, I can see remora input in HAL Meter but there is no msg regarding limit switch in GUI.
