V3.5 Improvements

The new Orbiter v3.5 is based on the well-known Orbiter v3.0, with several refinements that further enhance its extrusion performance. The technical characteristics of Orbiter v3.5 remain largely the same as those of Orbiter v3.0.

The main change in Orbiter v3.5 is the redesigned front heatsink. The new fin shape reduces air turbulence and helps eliminate the annoying ‘mosquito’ fan noise (~-10dB). 

The front heatsink is designed to be compatible with both the LDO hotend design and the E3D Revo ecosystem.

Note: The E3D Revo hotend is 4 mm longer than the LDO hotend!

The heatsink and hub housing have been widened by 0.5 mm. This ensures that the left-side extruder mounting surface sits further outward than the stepper motor body, improving mounting alignment. As a result, the Orbiter v3.5 is 0.5 mm wider than the previous v3.0.

The front heatsink and filament guide are now combined into a single part, improving tolerance control of the filament path and its distance to the filament sensor. This also reduces the number of parts that need to be aligned, making the design less sensitive to manufacturing tolerances. 

The input ring geometry has also been redesigned to accept a small PTFE coupler, ensuring the PTFE tube is mechanically retained rather than relying only on friction.

As shown above, the filament sensor has been redesigned using the same sensor switch as the Orbiter v2.0 smart filament sensor. This results in more reliable filament detection, reduced friction in the upper section of the extruder, and more reliable runout detection without false events.

The new sensor board features two RGB LEDs instead of one, so the Klipper RGB LED configuration must be updated to define two LEDs in the chain_count.

Drive Gear Tension Lever

The retaining screw for the secondary drive gear tension lever has been changed from a standard M3 screw to a custom M3 shoulder bolt. This allows the tension lever to pivot on a smooth surface rather than on the M3 threads, as was the case with Orbiter v3.0.

Knurled Spider-shaft design

Another change is a new knurled spider-shaft design. Compared to the previous precision shaft (octagon-shaped), the knurled version is easier to manufacture and allows the drive gear to be press-fitted with better alignment. This improved centering leads to more stable extrusion and smoother print quality, reducing visible diagonal artifacts.

Broad, detailed and comprehensible book on Linux Kernel Programming
Format: Paperback, Format: Paperback
I got on my desk a copy of "Linux Kernel Programmin (2E)" by Kaiwan N. Billimoria and will shortly mention what this book is about. It is a book that you can read cover-to-cover to have a better understanding of kernel development, but I see also how it can be used as a reference when you are going to throw C code at your compiler and build a linux kernel. There is a number of scenario why you might want to do that: - You are recompiling the kernel for a new machine that needs better support - You are going to implement a kernel module and you need some context - You are going to work on the kernel yourself While all of those use-cases for the book are technically a fit, apart from gaining some higher understanding I see the most out of it if you are going to code on the kernel itself. There you have everything that is needed. You can go back and forth between your code and the book, and still learn by doing. What mostly impressed me is the breath of the topics: the chapter about writing a config file for the kernel enlists a total of seven (7!) different strategies to get started with a configuration file for your kernel. Also a lot of side tools are mentioned to help out with kernel development and debugging. Quite some module development can be in theory done without fully understanding the details of the kernel itself, but the deeper you reach, the more you will need the details that are well discussed in the book. Memory allocation, CPU scheduling algorithms, the book does not try to save words and describe in detail and plain language most things there is to know, not sparing plenty of references to other books and articles. Also, the material is up-to-date with the latest kernel.

For begginers and also experienced kernel developers!
Format: Paperback
There are a few aspects about the book that I really like. One is that every chapter provides a very detailed and immersive look into a specific part of kernel development. Another interesting aspect about the book is that it is based on a very recent kernel version (6.1), which is also an LTS version that will be maintained for a few years. I am not aware of any other book about the Linux kernel based on such a recent version. The first 3 chapters of the book explains how to configure and build the Linux kernel (both natively for x86_64 and cross-compiling for AArch64). After that, chapters 4 and 5 explains all you need to know about how to write kernel modules. And starting from chapter 6, the book introduces different aspects of kernel programming in very detail, from the scheduler to memory management and synchronization. Get ready, because it is indeed a big book, with more than 800+ pages! I really think the book targets both beginners and experts. For beginners, it will be a deep dive into major kernel programming concepts (make sure you follow along the exercises proposed by the author). For experienced kernel developers, the book is really a refresher. Though I work with the Linux kernel for 15+ years, I can still learn a lot by reading the book. An old dog can always learn new tricks, right?

Organized well. You can read it section by section. Fantastic information. Clearly presented.
I like this book better than "what to expect" because this one does a better job of what you'll ACTUALLY expect versus telling you the throngs of horrible things that could happen to you or your baby. I'd rather be informed than mentally prodded with scary information. On one hand, it's good to know what could happen, so the other books you've probably already ordered are good to skim through, but this book I recommend reading all the way through. Easy to read, you'll actually have TIME to read it because you can read the age your baby is instead of a book that's all mixed up and organized by diseases and threats. Clear photos and explanations and tips on how to make your life and baby's life easier and better. I've understood my baby's needs better because of this book. I feel really glad I got it because it was the only book that really helped my daily life with my newborn.

we loved this well-illustrated book
As first-time parents, we loved this well-illustrated book, recommended it to one couple, and recently ordered another for an expecting couple in our family. Rather than grouping content by topic, the book is ordered chronologically, starting with Day 1 and progressing throughout the first year. Don't expect to read straight through; there are lots of pictures, sidebars, notes, etc. This makes it easier to find and retain relevant information (as opposed to reading a 100-page section on "Diet and Nutrition"). Provides a thorough treatment of most of the common issues, fun discoveries and concerns you encounter as a new parent.
