Common Failure Modes (CFM)

a.k.a. Continual F***ing Muppetry?

 

I expect every industry has its own "Top Ten" of CFM's. I'm not too proud to admit my own Day Job organisation has perfected CFM to a high degree. Here's my own Top Ten off the top of my head (which is now a peculiar shape from the sheer number of times head has hit desk)

1. Alerts and warning messages by emails to single individuals (not role-based distribution groups) - even after individuals are long-term sick or have retired/resigned/been removed from the business
2. Role-based distribution groups that cannot be updated - because the Human Remains department now regards info about individuals (the long-term sick or have retired/resigned/been removed from the business) as classified personal information.
3. Alerts and warning messages by emails - that cannot reach intended recipients because their mailboxes are full.
4. Alerts and warning messages by emails to role-based distribution groups - but nobody reads them - "somebody else" will do something
5. Processes that are completely undocumented
6. Processes that are documented - but the docs are in "safe places" that can't be accessed (because "security", or 12 different places for documentation depending on department/project/team/location etc etc that are private to them)
7. Requirements, specifications, designs, etc that were written and put in personally-named folders, not project-based, then when said person leaves their folder is archived or deleted and knowledge is lost.
8. Servers that have had no service packs, patches, updates etc for years, and/or are not monitored then run-out of disc space.
9. Network infrastructure that is so slow it take more than 24 hours to replicate 24 hours of data
10. Remote site network infrastructure/comms failures, but Infrastructure Team is unaware that remote sites are off-line, because remote sites have to fill-in online forms, but cannot do so because...

Any offers on other common CFMs?

i recognise at lot of there, but my top ten would also include

• Monitoring systems that send so many alerts that at the end of each day I just delete the 500+ emails... including the two alerts I should have done something about
• Write only documentation, The system specialist  produces reems of well docoumented information, that nobody else reads.
• Corporate inforced changes of documentation systems, Lotus notes--> word dokuments-> sharepoint->Confluence, each move leaving thousands of dead hyperlinks between documents 
• Teams chats that after a while contain loads of very useful information, that is not indexed, catorigised, and then deleted by someone as the chat is 'not in use anymore'
• Certifkat provideres who misunderstand GDPR laws, and insist that all supports cases must have a personal owner so that information on certicates reaching end of life get sent to a personal postbox that is no longer relevant.
• people who send very long complicated passwords as screenshots that can not be copy/pasted

Beautiful picture, I think the static grass is very realistic. So often static grass is better than green sawdust only because it is 3 dimensional. Here it looks like it is actually growing.

Here is another comparison print.  This is just about the maximum size the resin printer could cope with, the rough edge on the left is where the print met the raft. The two designs are not quite the same. The size of the arches was not quite right on the resin test print, There was also an error in the 1st statue enclosure on the left hand side. I corrected them on the same day I received my Bambu and this was the first test print made using one of my designs on that printer. In my effort to fit the whole design in such a way that the walls did not touch the raft, I tilted the wall a few more degrees and this resulted in resin print version of the new design becoming too warped to use! ( and it took 14 hours to print!)

I thought I would just post a picture of these prints in the building they were made for, which is still a work in progress

It's just the way the jobs market is nowadays. Everything is short term contracts or you want to move on to something else for more or better hours.

 

When something good does come up you get thousands of people applying for it as they are all on Indeed!

I work in IT where almost all applications never get beyond a HR department who have no idea who is suitable for the job, but only look at certifications and age/sex (even though they are not supposed to do that in Denmark).

I have been headhunted to the last two jobs I have. Never talked to a HR robot, just to the IT chef who wanted to hire me. On both occasions when I actually got to see the job advert for the post I had just be asked to take, I could see that I would never have had a chance of even getting to an interview, if I had applied for the job,

Surely you just move the Z measurement a few mil off the plate before rotating the print to the optimum angle. I print nothing on the plate on my resin printers, 1 usually raise by 8 mm, rotate then support. I also invariably use a raft under the supports,

That's what I did, but the highest end was warped in the Z axis, so the wall was not straight. I will end up using a new fdm back wall with resin vaults, and resin statues in the alcoves.

That's BS. I find the containers OK, but can't find a lid to suit.

 

Of course if I throw the container out, the lid pops out from hiding, leaving me with a lid, with nothing to put it on!

Tupperware is a perfect example of quantum mechanics: In any box, there may be a matching box and lid, but you only know for certain if you look for it.

This also means that if you have a box without a lid and you spin it, them somewhere in the universe a tupperware lid starts spinning by itself.

Thanks, that’s helpful. I guess I’m more interested in the Bambu alongside other FDM printers. I’m totally happy with the workflow for resin, although I can see how much more faff it is, and I definitely see me always using resin printers more. The speed is sort of attractive, but ultimately I start a print and leave it, so it doesn’t really matter. 
 

essentially I only ever use my resin printers for railway stuff at the moment because the finish on FDM is so massively inferior, and it’s whether the Bambu printers have closed that gap, for things like buildings where you’ve got lots of straight edges and hard corners where resin will not be optimal. 

Here is another comparison print.  This is just about the maximum size the resin printer could cope with, the rough edge on the left is where the print met the raft.

That could be a perfect example of a torture test for FDM printing. Smooth curves will always be the hardest thing to print.
Out of interest what layer settings and nozzle did you use ?

I've seen some remarkably good results from FDM when printed carefully with 0.2 nozzles rather than the normal default 0.4.

As I said I have only just got the Bambu. This is printer with the filiment that came with the pinter and uses 0.4 nozzles, Please excuse my ignorance. Is changing the nozzle size just done in software og do I need to change some hardware in the printer?

As a precis to stop the “well for detail buy a resin printer” comments - I have multiple resin printers and I have an FDM printer, so obviously I need more!

 

I’ve been impressed with what I’ve seen from the Bambu Lab X1/P1P (I believe they’re the same hardware, but no enclosure on the P1P and it foregoes some of the bells and whistles), anyone using one?

 

I confess I’ve never messed about too much with my FDM printer, it works fine for what I want it to do (which is basically never railway stuff), but the Bambu Lab printers really look like they’re blurring the lines (often literally) between FDM and resin. Obviously at a fundamental level the technology is still the same, but with the speed and the finish they seem to achieve it’s a tempting proposition!

I have a Elegoo Mars 3 Pro resin printer for about 4 months, and have just bought a Bambu Lab X1/P1S.

The Bambu is streets ahead in ease of use. It is much faster, there is no need for cleaning or curing, The P1S has a webcam, so I can see how the print is going from my PC. It is also on my network.  The build volume is quite a lot larger than the Elegoo, and the bed is self-levelling. I have not yet had any failed prints on it.

The Elegoo has only a USB and is very fussy about USB sticks. Only about 1 in five of those I own can be recognised by it (and that does not even include the one that is packaged with the printer!) Just look on the internet and you can see that this is a common fault.

My limited experience (I have done about 30 prints on the Elegoo) is that it can produce much finer results for some types of structure than the Bambu, but there is a lot of fiddling involved. I find it hard to prevent warping at the edge of prints sometimes.

Here is a picture that shows the strengths and weaknesses of the two printers the design is the same, I used Autodesk Fusion 360 to create the design for a vaulted roof in the entrance to a model of Hatch Court. The fusion file is exported as an STL file. For the resin printer I use LycheeSlicer to produce the file. Because of the size the print had to be angled diagonally to fit the print volume and this results in a lot of wasted supports.

The Bambu print was sliced in Bambu Syudio, which is very easy to use. It was just printed flat on the bed of the printer, so no wasted plastic.

But the print results show clearly why I use the resin printer for this type of object.  They are the same size even they do not seem to be so in the photo. The Bambu has a lot of lines visible. I am not sure that I would say it blurs the difference.

I forgot to say that the Bambu print took 1.5 hours and the Elegoo print took 12 hours + 1 for cleaning and curing. My practice is to use the Bambu for test prints and then the resin for the final production

One of the manufacturers really has to bite the bullet and produce a full range of "generic" short(ish) bogie coaches suitable for the (approx) 1900 to 1920+ period.

 

I know that the newish manufacturers concentrate on accuracy, but someone has to do them and the different liveries will take skill.

The problem is that everyone want a 'generic' range of coaches, that happens to be a precisely accurate model of the particular coach they need!

You can resin print track bases (we’ve discussed that on Hayfield’s thread I’m sure), but obviously Martin is pushing ‘plug track’ utilising both, and the stability and build volume from an FDM base will be advantageous. 
 

I’ve got an Elegoo Neptune (because I had a Saturn/Mars/Mars 2 and the brand was a known quantity), and it’s been a good printer. Sorely tempted by a Bambu P1P.  

I have a similiar printer setup I have an Elegoo Mars3 Pro and have just bought a BambuP1S. I can recommend it. First impressions are that it is so much easier to use than the resin printer. There is no washing and curing to start off with. The Bambu has auto plate levelling which saves a lot of time and effort.  It even has a built-in webcam so you can see how a print is going!

Here er a sample print for a model of Hatch Beachaumps court that I am building mainly from card. I need to print the inner wall of the entrance hall The grey print is from the elegoo using ABS like resin. It is a rough test print is check sizing. It took about 10 hours to print. The green print is from the Bambu FDM using the basic filament that came with the printer it took under two hours. The design has been modified between the two prints to correct sizing and some missing details.

Somehow the FMD printer seems to be able to print in midair. It printed the window frames fine. The resin printer has to have a lot of supports, and print at angles to be able to print the frames in midair. Just look at the difference in the slicer plans designed!

It costs about twice the price of the Elegoo. But is going to be used more, I think. The running costs will be lower. Especiallybecause you don’t have to buy IPA to rinse the prints. You can see more banding in the Green print and the door frames are more ragged. I suspect I will do test prints in FDM and use Resin for the final 'production' print
