BRL‑CAD Release 7.24.0, Archer Alpha

After nearly an entire year's worth of intense collaborative effort, the 7.24.0 major release of BRL-CAD is now available for download! This is the alpha release unveiling of Archer/MGED, a preliminary interface update to BRL-CAD's graphical geometry editor. Some highlights include an integrated graphical tree view, a single window framework, drag and drop geometry editing, information panels, shortcut buttons, improved polygonal mesh and 2D sketch editing, level of detail wireframes, NURBS shaded display support, and much more. As alpha software, this new MGED prototype aims to provide functional feature parity with the antecedent MGED interface while introducing changes. Prior to upcoming beta testing where the emphasis is predominantly on stability and usability, this alpha status solicits feedback from the community on capability and features. This release also includes various improvements to BRL-CAD's ray tracing infrastructure including CPU thread affinity locking for faster performance, more consistent grazing hit behavior, expanded volume and surface area calculations, numerous bug fixes, and more robust NURBS evaluation. Following BRL-CAD's interface deprecation policy (see CHANGES file), the Jove text editor is no longer being bundled. Various converters including the STEP, Patch, and 3DM importers received robustness improvements.

History of BRL‑CAD

In 1979, the U.S. Army Ballistic Research Laboratory (BRL) – now the United States Army Research Laboratory – expressed a need for tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no CAD package was found to be adequate for this purpose, BRL software developers – led by Mike Muuss – began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD. Development on BRL-CAD as a package subsequently began in 1983; the first public release was made in 1984. BRL-CAD became an open-source project on December, 2004. The BRL-CAD source code repository is believed to be the oldest public version-controlled codebase in the world that's still under active development, dating back to 1983-12-16 00:10:31 UTC.

Report: Ricoh SC569-00 Error Code Analysis Error Code: Machine Type: Ricoh Color Laser Copiers (Commonly MPC3003, MPC3503, MPC4503, MPC5503, MPC6003, MPC3004/3504/4504/6004 series)Error Type: Service Call Code (SC)Primary Definition: Toner Supply Motor Lock Error 1. Error Description & Significance

Fusing belt – Look for cracks, wrinkles, or sticking.
Thermistors – Clean gently with a soft cloth; check for deformation.
Pressure roller – For flat spots or contamination.

Initial Power Cycle: Turn the machine off and unplug it from the wall for at least 60 seconds to clear temporary electronic glitches. Inspect the One-Way Gear: sc569-00 ricoh

Definition: The fuser unit pressure release motor failed to move the pressure roller to its "home" (released) position within the required time. Report: Ricoh SC569-00 Error Code Analysis Error Code:

When this error appears, it typically points to a mechanical or electrical failure within the fuser unit's pressure release system. Fusing belt – Look for cracks, wrinkles, or sticking

Motor Failure or Blockage: The pressure release motor may be locked due to an excessive load, or the motor driver itself could be defective.

Hardware Replacement: If cleaning does not work, the One-Way Gear (D0BQ1375) or the Pressure Release Gear No. 3 (D1751377) may need to be replaced. How to Reset the SC Code

Listen for motor noise.
Observe fence movement.
If no movement → check motor/connector/voltage.

Step 5: Replace the Fuser Unit (Recommended for Production Environments)

For business-critical machines, individual component repair is risky. Replace the entire fuser unit with a genuine Ricoh OEM unit. After replacement:

BRL‑CAD Logo Competition!

The BRL-CAD open source project is interested in a new logo so we're holding a competition for inspiring ideas from the community! You have the chance to win cold cash, make friends, and obtain world-wide notoriety.There are cash prizes for first, second, and third place selections plus an optional bonus. Winning selections will be announced by August 15th. Pen and paper work just fine. Scan it in and e-mail it. You're welcome to use any tools or software to design the logo. That said, you can double your prize amount IF (and only if) you design a selected logo only using BRL-CAD tools. See here for an example of what I mean. If you're going for the bonus, submit a ".g" geometry file in addition to any image file(s) you provide. In case you're wondering, shoving an image into a .g doesn't count! With our steep learning curve, though, it's definitely not for pansies nor recommended if you're a newbie. The bonus is just for the added awesome factor. The BRL-CAD "mascot" is a moose. Feel free to incorporate that into your design or come up with something more abstract. Other keywords relevant to our project domain are listed in this file.
