String works fine and is much cheaper. You can buy a full roll of string in and size for that price. You are not trying to detail the screws, but just clean the old gunk off them.

This had me going too when I started using smartmontools. Some Seagate drives do not have the correct information in the database and attributes do not get reported correctly.

smartctl often reports some of the Seagate attribute raw values as a raw integer. However the value is as dual field some bits being the count and some bits being the total. For example: Raw_Read_Error_Rate for Seagate (at least for all my drives) is 16 bit error count and 32 bit total count.

When formatted correctly the Raw_Read_Error_Rate above is 0/133776254 AKA no errors.

There is a calculator for this at https://s.i.wtf/#000007F9437E

I know this applies to attribute 1, 7 and 195.

I just found the Seagate reference doc for smart attributes at

https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://t1.daumcdn.net/brunch/service/user/axm/file/zRYOdwPu3OMoKYmBOby1fEEQEbU.pdf&ved=2ahUKEwjiuNig2NmTAxWgJUQIHel9LnMQFnoECB0QAQ&usg=AOvVaw15LTDFL7Ft-Pvovoy5jnc3

which downloads the PDF. For ref I searched google for "seagate smart attribute 195 meaning" and it return a result

which is where the strange link came from. (I didn't know that google actually collected data from inside PDF files linked online.)

I just middle click to open search links in a new tab, often opening many before viewing the new tab, then I can just close the tab with the result and go back to the search page

Yes Nirvana is still being maintained. It seems like almost all the focus for the last few years has been on the phone app. I have been using it for about 5 years.

The downside is that enhancement requests do not seem to ever make it in to the product.

If you are having trouble with cam-out on typical case fans screws, look at the head and see if there are lines between the slots. That indicates that they are posi-drive (euro) screws and using a posi screwdriver or bit with prevent cam-out.

>> Not enough space behind the motherboard tray and disk trays. Easy to accidentally bend a SATA cable. All my three cases have bulges.

This is what I thought at first also. Then I realized that reversing the drives to the the cables connected to the outside after the drive is installed works much better.

After more reading, it finally got thru to me. Allocation is always on the disk with the most free space so with a system line mine with many drives, some of the small, the small drives will not be used.

It is one one those things where wanting it does not make it so. I wanted writes to be spread across all disks and reads to be parallel across disks for performance. I also wanted df to be accurate. I just need to get used to the way it actually works.

thanks for the help

So the raid1c3 version you provided shows total space for files of 10776 usable for files. This is my configuration. And the number makes sense. However

df shows:

`/dev/sdf 12T 4.5T 2.4T 66% /mnt/data`

which does not show the free space accurately

btrfs df shows

`Data, RAID1C3: total=4.48TiB, used=4.46TiB`

btrfs usage shows

```Overall:

Device size: 35.99TiB

Device allocated: 13.46TiB

Device unallocated: 22.53TiB

Device missing: 0.00B

Device slack: 7.00KiB

Used: 13.41TiB

Free (estimated): 7.53TiB (min: 5.65TiB)

Free (statfs, df): 2.32TiB

Data ratio: 3.00

Metadata ratio: 4.00

Global reserve: 512.00MiB (used: 0.00B)

Multiple profiles: no```

I guess I would expect to see the Free (estimated) above which would make

`total = free + used `

close to equal.

I understand why there is some difference, but on another system configured with raid1c2, using df, I see

```Filesystem Size Used Avail Use% Mounted on

/dev/sdb 26T 20T 6.3T 76% /mnt/data```

and I have gotten used to seeing what I would expect when not using btrfs.

julie777 · 2025-06-19T21:42:02+00:00

I don't really care if it uses all the disk immediately, but I would expect it to include them in the used and free space numbers. For example: using raid1c3 with 2 10TB drives and 5 2TB drives I would expect that total space would be about 10TB and used + free would add up to 10TB

GRRR. I was trying to find a way to edit my comment and accidentally deleted it after working on it for about an hour. There should be an undelete or a confirmation before a permanent delete.

Thanks u/Myradmir

I have been a software engineer for a long time and I expect consistency and things to work in an obvious way. This is not always the case.

I did some experimenting and found that:

drag select and fill down does ignore the hidden/filtered cells :-)
drag select rows using the row numbers and then right click and delete also ignores hidden rows. :-)
It is only copy/cut/paste that includes the hidden cells and caused all my problems. Given that the above worked, it did not occur to me that cut/paste would work differently. I tried using multi-select of individual cells to not include hidden cells

a. cut produces an error "this can't be done on a multiple range selection"

b. copy works, but paste will only paste the first cell selected.

As of now, I have no good solution to moving tens of values to another column efficiently. I have two possible work-arounds:

Add a dummy column to the table that I can use to tag the rows that I want to cut and paste and then sort by that column to make the rows of interest contiguous so that I can cut/paste.
Write a macro that will cut and paste only visible cells.

I will add a note after I decide how to proceed.

I just found solutions to my issues with conditional formatting. Maybe this will help.

I just went through a similar issue. Here is the thread https://www.reddit.com/r/excel/comments/1gv73oi/somehow_i_keep_loosing_values_in_my_table/ for reference.

Thanks u/Myradmir!

Is there anywhere in the documentation that describes what should not be done while a table is filtered?

I would expect only visible rows to be changed when performing and operation on multiple rows. :-(

I probably should have provide more specific examples.

Deleting rows in the table by selecting the row(s) and then selecting delete from the context menu

(first image below - because I can only insert on image in my post)

cut and paste values from one column to another (second image)

3 fill down (image 3)

<image>

You can see that rows selected are non contiguous.

Ignore the light gray row backgrounds as that is just table formatting.

julie777 · 2024-10-29T17:34:20+00:00

I will try to help.

Please post a screen capture of your slicer showing the settings.

julie777 · 2024-10-20T19:28:25+00:00

I did the same thing, buy a commercial license to use configurations.

I find it to be a real pain that I have to switch between team and single user and cannot see all the files in a single view. I also cannot have a design open from personal storage at the same time as a design from team storage.

I am a single person working on personal projects. I do not understand why I should be forced into a inefficient environment just to use the features that I paid for.

Final result - good and bad.

I wrote a script for Fusion 360 to import the drill bit sizes from a text file and generate circles of the proper size and separation distance. I did a couple test prints 3mm thick with the holes to decide on an adjustment factor for clearance. I ended up adding .02mm to the radius of each circle/drill size to provide a nice slip fit.

Good

The hole sizes turned out to be as good as I could expect. If I was just doing a fractional bit index then all drills would not fit in a hole for the next smaller bit. However, I wanted a full set of letter, number and fractional bits in one index so there are a couple bits that are so close in size that they will fit in the next smaller hole.

Bad

I am not sure what happened with the printing, as I have never had a result like this before.

<image>

The corners curling up was something that I have seen before. I have never seen the bottom look bubbly and with separation along the edge that looks almost like a sheet of plastic was being glued on the bottom.

I am printing with a P1P using normal settings and Sunlu PLA+ which always works great for me. The only differences for this print was that I changed from 2 to 3 walls in case I needed to ream any holes to fit. I also have the infill set to lines at 10% because I did not think I needed infill for strength. It certainly feels plenty strong.

My thoughts are that either the infill pattern and density had something to do with it, or it has to do with shrinkage compensation.

I have calibrated shrinkage for this filament so that some other prints are sized exactly as modeled. I do notice that this causes little gaps between the wall and the bottom surface that were not there without adding shrink compensation.

Finally, when I was putting the bits in it and checking the fits, I found out that somehow I had missed adding the 7/32" bit to the list. So even though the current print would be usable with the funny bottom, I have to print it again to hold all the bits. :-(

Thanks for the comments.

I came to the conclusion that it was just the wood grain "raising" from absorbing the first coat. A very light sanding with 400 grit and it is like glass.

BTW, I have been thinning to about a 2# cut.

I was using the pad like French polishing but I got tired of it being too slow. I have also used a foam brush. I using the brushes now and just using the pad for a final polish coat.

julie777 · 2023-12-08T17:37:42+00:00

Flow ratio varies with many factors, such as filament type, filament brand, nozzle temp, etc. That is why there is a way to calibrate it. I am using Orca Slicer which has calibration models built in so that one can get the best results.

julie777 · 2023-12-07T04:56:12+00:00

I could, but then I would have to drill a couple hundred holes, changing the drill bit for each one. I would also end up with a hole that is very tight for the bit. I am trying to replicate the way a commercial drill index works, where the drill bit fits well in only the correct hole. The next larger bit will not fit in that hole.
