Hello Joel - Et Al (The team)

Firstly.... Many thanks for your work and publishing openly. I am not a coder, just a user with a few bit skills

I got interested having seen a post on the RPi forum.

So...

I am currently using Picnc on Machinekit, which is working well for me, but may well be suffering bitrot???? Hmmm

Looking for a way forward. I have had a brief tinker with this ( Not impressed with Etcher so far !!  failed some 5 times on Win & linux  on 2 SD cards, had to resort to Win32 DiskImager to get a working?ish  result... 2 SD cards 4 machines Hmmm)

Thought I would mention it. I'm sure I'm not the only one.Sorry for the critique but us humble users are a bit ... Variable-Different?

So to a more positive note... My compliments on a good choice of bundled apps with your distro to suit a user base inclined to Mech & Tech.

I'm rather looking forward to this distro :)

Cheers

MrGreg

Sorry to hear your disk install was giving you grief.

Which card and win release are you using?

This is our first image release that we tested by cloning onto several versions of the class10 Sandisk 32GB sdcard.  In general, damaged sdcards from power outages can cause failed/corrupted  writes, and some brands may need zero'd if drm software has fiddled with the boot sector region. We used a ram drive overlay root for precisely this reason.

The recent win10 bug repeat with the user file store issue could also have something to do with how etcher is extracting the archives.  I will have our "windows user" look at it again before we release rc1.

Cheers,

~J~

chkflash.exe for SD and USB will also check goofy PNY cards

@tara

That site looks dodgy as a $3 bill, I hope you at least used the original publishers site for the download.  I'll see you at the regular meetup anyway... :-)

Does anyone know if these tools work like AltraMayor's F3 in linux for surface testing sdcards on Win7/10 ? ( I will add an F3 build/help page, so people at least are able to properly diagnose failing cards on a linux machine. )

First card tried:

Sandisk Extreme 32G ( nearly new)

OS (s) Lununtu18 + Etcher

Tried compressed and uncompressed

Win7 + Etcher compressed

Another Win7 box + Etcher compressed

All failed

SD card 2

Samsung Pro 32G ( moderately used for RPi OS)

Lubuntu 18 + Etcher uncompressed

Failed

Win7 + Win32 DiskImager uncompressed

Success

I will double check the Sandisk card with Win32 DI and uncompressed image to see what happens when I have time
