Rance,

? ? ?Take a photo of what you are trying to do and post in the 'Photos" section.? Maybe we can see something that way.

Rance,

Since you have Win7, if the 'Windows' tab shows it as open, go to the bar on
the desktop of open programs. It too should list the different panes within
JMRI that are open. Right click on the one of the loco and pick 'Maximize',
that should make it take your whole display. Then you should be able to grab
the corners and resize it to something that fits the display. Then close it.
That should keep that last size and location and use it next time you open
it. At least I think that's what I do, my fingers know the steps better than
my memory.

If this is the case, the last step is removing the file that retains all the
size and location details for everything in JMRI. It would then start with
the system defaults and that would work. But that is like a nuclear option,
you lose all record of every window within JMRI. The file is named
UserPrefsProfileConfig.xml but as I say, that is a last resort.

It sounds like the hardware is fine, because it was used with the desktop machine OK (It was the same CAN-USB4, cables, etc, right?)

Since single events can be lost, it’s probably not a matter of internal queues getting too big, etc.

Does JMRI seem to be constantly awake? I.e. if you ask it to change a turnout, does that always happen promptly? Or are there occasional long delays?

There might be an issue with the USB subsystem. I’ve seen a bad cable or device generate a _lot_ of not-really-visible USB traffic while the machine tries to cope. What other USB devices are attached? Powered or unpowered hubs? If you have a USB keyboard, does it ever drop keys?

Hi Dave

OK I see it now. The masts that have the NX associated with them are held until a route is set from them. All quite sensible.

Thanks for everything on this

Larry,

Also look at the idea of 'kernel', it is a tool to keep a set of cars
together. I think it was designed for unit trains and passenger car sets.
You might be able to then use an extra digit for those cars to keep them
identified.

I have a large yard with a standard ladder on both ends, so all tracks can be accessed at either end.? My tracks are defined as FIFO, so we set out from one end and pull from the other.? Pretty straight forward I hope.

Now, I want a have a periodic deep cleaning of the yard.? I want to pull every car off, dust and clean tracks, track maintenance, etc.? Once completed, I want to return all of the cars in their original spots.? If I do this for an industry with spurs and spots, it's no big deal.? Not as many cars and all cars have a specific spot.??

Does OpsPro keep track on the specific order a car is in a yard?? Would I have to take a picture of the all cars in order, so I can put them back in order???

All help appreciated.

Thanks,
Larry

Simply add ”-2” (or -1, or whatever) to the road number, e.g., 102766-2. JMRI won’t display the “-2” on the manifest.?

Thanks Ken.
I'll have to take a look at that.? For my long distance train that doesn't get broken up, it's not much of a big deal.? But for locals where the individual cars will be set out at either spur spots or a yard track, we still need to know which car is which.

Rance,

Are you saying you see the loco listed in the roster, but it won't open. Or
is it not showing up in the roster list?

Things to check. First Help->System Console, this will show any internal
errors happening when you try saving the entry. Second, Debug->Rebuild
Roster, this will rebuild the index of the locos in the roster directory.
Third, Help->File Locations, do the paths for everything, like the roster
make sense. Fourth, after you asked it to open the loco entry, check the tab
'Windows', does that show an entry for the loco? If that does, that says it
is open, but somewhere off your viewing screen. Depending on which type of
computer, there different magic keystrokes to get it back to where you could
see it.

See if any of these help you out.

Larry,

I don't recall if Ops allows letters in the road number. I'm thinking like
the early days of the ABA locos, they used trailing letters. If you watch
most container cars they put an A, B, C... on the different segments of
those too. Might be one easy way out. I think Dan did something for this
sometime along the line.

Andy,

I've found the quality and speed of the SD card a bigger impact that the
version of Pi. I found it by convenience one day. I had asked my wife to
pick up a spare card so I could make backup images. She happened to pick one
of the fastest available at that time. When I tested with it, I was amazed
at startup speed etc...

Thanks Matt.

That worked.? By giving them a suffix number, the manifest shows exactly what I needed.

Another question.? How do you all handle cars with duplicate road numbers?? We have lots of cars on this train with duplicate numbers, and renumbering would be a huge undertaking.? I thought of creating one car with a total length of all the cars, so the manifest would show only picking up one car, but the length would be correct.? Note: this is a long distance train from staging to staging, so there is no need to break up train at either end.

We've just starting using a Raspberry Pi running JMRI for controlling the Faller roadway on an N gauge club layout - Wickwar.

We've managed to successfully control the roadway at a couple of exhibitions - and the use of JMRI had proved itself very popular with public and club members alike (Thanks go to the JMRI team!!)

However, at the last exhibition I noticed that although events from the Pi seemed to be fine, it seemed that some incoming message to the Pi were missed, hence the layout editor track plan and sensors were not updated with new information.

I created a new Pi image from scratch based on the "Raspbian Stretch with desktop and recommended software" April 2019 Release. Kernel version: 4.14.

JMRI is also 4.14 (what a conincidence....)
Interface is using a Merg CAN-USB4 to a CBUS system.
I'm NOT using the Wi-fi on the Pi - I opted instead to offload that job to an old domestic wi-fi router to avoid any potential loading issues at exhibition. I believe the wi-fi side is working fine.

I originally created the image and ran it on a Pi 2. After seeing the problem I upgrade the Pi (but not the SD card) to a Pi 3 thinking it might be a load/performance issue. The problem remained the same (missing events).

I originally developed the JMRI layout on an Ubuntu machine (now version 19.04), using various JMRI versions, although now using the same 4.14 version. I've used this on the layout with no problems, again connecting with a CAN-USB4.

Subsequently I've run the 2 systems (Pi using RealVNC and Ubuntu) side by side (each with it's own CAN-USB) connected to the same network
each running JMRI using the Merg Console to monitor events. There was only a few inches between the connection points to the layout.

The consoles showed quite clearly some events missed by the Pi system. This occured even when the network was very lightly loaded
i.e. with an event missed in isolation (separated by seconds from other events).

Clearly there are lots of variables involved and I've only scratched the surface in describing the details of the
layout and computers systems. I guess what I'm really after is a few pointers on what might be causing this, as it's
rather fundamental to progressing further!

I'm hoping to try to simplify the problem down, (I have very limited access to the complete layout) but am struggling to know where to look first.

Any ideas welcome!
Thanks
Andy
