Gonna leave it here because someone might find it useful and my googling didn't come up with the answers that I liked.

So. I successfully switched my TerraMaster D2-310 from RAID1 to SINGLE mode, where each physical drive corresponds to a distinct logical one. Despite multiple sources stating that such a switch requires wiping the drives, I found a method that worked for me. Keep in mind that results may vary, and this might not apply to all enclosures.

Here are the steps:

1. Power down the enclosure, disconnect it from your PC, and remove Drive 2 from the enclosure.

2. Connect Drive 2 to your PC motherboard using a SATA cable.

3. Turn on your PC and ensure Drive 2 functions properly, allowing you to read and write data.

4. With the enclosure powered off, switch the MODE setting on the back of the device to SINGLE mode. WARNING: Do not, DO NOT press the Reset button, as it will most likely wipe your drive!

5. Power on the enclosure with Drive 1 inside and connect it to the same PC where Drive 2 is already connected.

6. Windows cannot mount Drive 1 due to its signature matching that of Drive 2, which is desired.

7. Open Disk Management, locate your "Offline Disk," right-click on it, and select "Online." This action changes the signature of Drive 1, effectively removing it from RAID.

8. You can now navigate to the root of each disk and delete any hidden folders containing RAID information. I removed the 2 folders starting with a "." (dot).

That's it. Aside from other obvious benefits of NOT having to tie 2 drives together, I believe I will get better longevity of my second drive now because I will use it to back up only the important stuff once a day.

Ever since getting my benchtop CNC running, I have not been very happy with the lack of manual control over overrides and buttons.

This DIY Engineering video gave me a great idea: build one myself.

I wanted the smooth speed and feed overrides, so I decided to not go with HID device, but instead with a full serial control paired with a custom plugin on the UCCNC side.

Here is the Fusion design of the enclosure:

And here it is 3D-Printed.
Acrylic face engraved from the back side and painted.
And all buttons and controls mounted:

All I have to do now is wire the Arduino board, program the plugin, and test it!

Update:

Here is the video of the pendant in action:

1. PCB Design

Design notes:

• All resistors used were 10K
• Speed and Feed potentiometers are 10K
  Their pinout goes Wiper->ground = 0%, Wiper -> +5V = 200%
• Axis and Handwheel Increment rotary switches are 4-position and their pinout goes like this:
  Axis select 1-X, 2-Y, 3-Z, 4-A, C-Common (+5V)
  Handwheel Increment 1-0.0001, 2-0.0010, 3-0.0100, 4-0.1000, C-Common (+5V)
• All function buttons such as Jog +/-, M1, M2, etc are sending +5V signals to the digital pins D2-D12
• D13 digital pin is connected to a LED indicator and is used to tell the user that the Pendant is allowed to send signals to the plugin.

If you don't have a 3D printer and/or a CNC Mill, please contact me and I will send you a 3d-printed enclosure and the 3d-printed or milled acrylic face plate:

• 3D-Printed Black PLA Enclosure (shown in pictures): 30$ + shipping
• 3D-Printed Black PLA Face Plate (optional): 15$ + shipping
• CNC Milled and Engraved unpainted (clear) acrylic Face Plate (shown in pictures): 30$ + shipping

3. Arduino Setup

• Install the Full Firmata library onto your Arduino Nano (Or any other Ardiono that supports USB Serial Communication): StandardFirmata sketch used for Arduino NANO is also added to the release package

• Please note that you might need to install Arduino USB Driver in order for your Arduino to work on the target computer!

4. UCCNC Setup

• Download the latest LEETArduinoPendant from the releases and extract it to your PC.
  https://github.com/swindex/LEETArduinoPendant/releases
• Copy the LEETArduinoPendant.dll plugin file to the C:\UCCNC\Plugins directory!
• Copy the Solid.Arduino.dll file from the Solid.Arduino release folder to the C:\UCCNC directory.
• Please note that you might need to install Arduino USB Driver in order for your Arduino to work on the target computer!
• Launch UCCNC.exe, go to Settings->Configure Plugins, and mark the LEET Arduino Pendant plugin as Enabled and Call startup
• After everything is installed, Arduino is connected and UCCNC is running, press the "Enable" (+5v to D2-B-ENABLE ) button that will tell the plugin that the pendant is ready to send signals! D13 (LED+) will then have a continuous +3.3V signal alerting you of that!

Since my garage/shop has a limited workspace, I have long wanted to upgrade the big and clumsy computer I used to drive my little Prolight desktop CNC to something more elegant and convenient.

TL;DR: You can read about the printing settings and download files on Thingiverse: https://www.thingiverse.com/thing:4754968

After quite a bit of googling, and testing the UCCNC control software that i already have I decided to re-use my old Z83 mini-PC with Intel Atom processor.

Then I ordered a SunFounter 10.1" touchscreen monitor with a nice resolution of 1200x800 from amazon.

Since the display does not come with an enclosure I decided to design one myself.
A good opportunity to dust off my 3d modeling skills:

I try to not comment on things outside of my immediate area of knowledge or specialization.
But this one caught my eye and I thought it would be interesting to share with you guys.

So the news in a nutshell is Amazon applying discounts to products that third-party vendors are selling on its platform.

For example. Company "A" is selling its smartphone for $1000.
That is the price of the product on their online store and brick-and-mortar stores and other platforms like for example Amazon.

There have been purely electric cars long before the Tesla Model 3.

But Tesla has made it cool. Sort of like how Apple made the iPhone cool, Tesla made not just gas-free, environment-saving cars. It made cool high-performance vehicles that are fun to drive.

And nobody really cares that Chevy Volt has already been available for years for a comparable price. Couple of days since its unveil, the new Model 3 has already outsold the Volt. Not a small feat, considering, they are only going to start delivering in about a year!

But Tesla, like Apple, like Amazon is in many ways a disruptive technology.
