Hey everyone,
Over the past three weeks, I took some time off—not just to relax, but to prepare. Prepare for what’s ahead. Because the T250 is finally ready to be shown to the world.
The design has been built and tested by over ten Alpha testers, and their feedback made its way back into the printer. THEOS got a major polish too—many of the early quirks have been ironed out, a...
2025-05-12 15:20:27 +0000 UTC View PostOver the past week, I've mainly been focused on making improvements to Klipper. I absolutely fell in love with the real-time bed-level scanning that the BDSensor provides. Seriously, when it works, it's incredible! It nails the tolerances so perfectly that the first layer sticks flawlessly, even without any adhesive—yes, even at full-blown BSO speeds! Honestly, this is the first printer I've ...
2025-04-07 16:04:01 +0000 UTC View PostOver the past week, I focused on enhancing the resolution and quality of fine details in certain prints. Printing Minatures on an FDM Printer is hard. You're facing issues like:
Cooling: Precise cooling is crucial to quickly solidify each extruded layer, preventing deformation.
Pressure Control: Maintaining consistent pres...
2025-03-31 15:28:02 +0000 UTC View PostHey everyone! Sorry things have been a bit quiet from my side this past week. I was still recovering from COVID, and trust me—running a loud CPAP printer right next to you with a pounding headache isn't fun.
So I was focusing on some enhancements to the THEOS firmware. Over the past few weeks, I've noticed that the BD sensor occasionally produces false-positive readings during the secon...
2025-03-24 16:51:43 +0000 UTC View PostLast week was Carnival in my hometown, so productivity took a bit of a hit—too much celebrating, and I ended up getting sick. But that didn’t stop me from printing!
For the next few weeks, my focus is on real-world prints to fine-tune the setup and slicer profiles with actual user feedback. Expect a bunch of short videos showcasing high-speed prints, starting with this puzzle:

2025-03-10 15:16:17 +0000 UTC View PostToday, I want to share some of the insights I've gained over the past few years about Input Shapers and their impact on high-speed printing. And to make things easier, I’ve prepared something for you:
Over the past three days, I’ve printed a variety of test objects to show the effects of different I...
Many people in our community showcase how they achieve a high-speed, high-quality 3DBenchy. While I genuinely appreciate seeing these fast Benchy shredders, I’ve learned that the 3DBenchy isn’t the best model for tuning a high-speed printer. Consequently, I stopped using it once I began fine-tuning my T250 slicer profiles.
So what's my issue with it? Here's a sliced benchy on my curre...

Over the last four or five weeks, I’ve been asked twice whether the side blowers are truly necessary for the T250, or if removing them would be a good way to save some money. The answer isn’t as straightforward as it might seem, but it’s definitely worth discussing—so I decided to cover it here on Patreon.
To explore this topic, I’ve set up the following test scenario:
A new month brings another confession. I seek forgiveness for spending numerous valuable Patreon euros on low-quality Chinese products. However, I have found something that might be intresting for all of us.

2025-02-12 17:32:01 +0000 UTC View PostOne of the most frustrating issues I’ve faced over the past few years is the “mcu: timer too close” error. It occurs sporadically whenever a high enough CPU spike happend for a long enough time.
Today, I want to break down why this error happens, share what I’ve done to fix it in THEOS
Dear Supporters,
Over the past four weeks, I worked on integrating some pretty advanced klipper features into THEOS. Some of them you already saw here on Patreon in Action. Below is an overview of the latest developments:

2025-02-07 14:54:17 +0000 UTC View PostLast week, my productivity took a hit as I spent most of my time nursing a Covid infection with tea and binge-watching shows. However, by the weekend, I began to feel better and was able to resume work on the printer.
One long-standing task on my to-do list was to develop a holder for managing the toolhead cables. I’m quite proud of the solution I developed: a clip positioned at the fro...
2025-02-03 15:36:45 +0000 UTC View PostOver the last days I was struggling getting non-linear pressure advance working on my T250. For those who don't know about it it's basic a way of defining a PA value that behaved stronger at lower flows and gets less and less the higher the printing flows get. It's completely bleeding edge, no documention, no best practices but im confident that with non-linear PA the boundaries of high speed p...
2025-01-24 18:32:43 +0000 UTC View PostAbout a week ago, I calibrated my T250 to a level where I felt confident fine-tuning a quality profile for it. I began my initial prints and noticed a fuzzy orange skin effect along the outer perimeter of all the prints:
My initial hypothesis was that the issue was related to VFA. I knew that lo...
2025-01-21 18:02:01 +0000 UTC View PostI was incredibly lucky with my Z-Motors—the embedded leadscrews were 100% straight, resulting in flawless prints without any print bed-related artifacts. However, some of my alpha testers weren’t as lucky. Taking their feedback into account, I decided to design an option for Oldham couplers to accommodate those with bent leadscrews or who use motors without integrated leadscrews.

Today, I am starting a new series where I will make a confession and seek forgiveness for past mistakes—especially for the numerous valuable Patreon euros I spent on low-quality Chinese stuff. But as always, when digging, you might find a lump of coal or perhaps a diamond. In this series I want to share one Diamond I found every month! Lets get started:
Over the last 3-4 days, I’ve run into 2-3 sporadic MCU shutdowns with the Error Message: MCU shutdown: Timer too close. The reason for that error is in most situation a bottleneck caused by the Host CPU. I suspect the combination of speeds exceeding 1000mm/s, High Precision Stepping enabled, Polynomial Input Shaping, PA synchronization, and microstepping set above 16 is simpl...
2025-01-10 16:31:14 +0000 UTC View PostToday I want to share with you one Step of my tuning process of my new T250 3D Printer.
One of the biggest headaches we all face: achieving consistent extrusion—or any extrusion at all—when pushing speeds over 300mm/s.
The reason why most printers struggle here is because the pressure of inside the hotend is too big causing oozing in both sides of the hotend, one side you see as...
2025-01-08 15:33:01 +0000 UTC View PostAfter more than a day of programming, I successfully ported Dmitry Butyugin's advanced Klipper features to my own Klipper fork. It was somewhat challenging because his developments were based on a very old version of Klipper, and numerous changes have been made to Klipper since then. As a result, I had to rewrite significant portions of his code to ensure compatibility. But enough of the progra...

2025-01-04 20:08:22 +0000 UTC View PostDear Supporters,
Over the past two weeks, I’ve made significant steps forward in developing our 3D Printer Operating System, THEOS. Thanks to your support, I’ve implemented new features in Klipper, enhanced configuration options, and expanded device support. Below is an overview of the latest developments:
Hey everyone,
The year may be winding down, but the new THEOS features aren’t! I managed to squeeze in some coding time over Christmas to overhaul the Klipper Config Parser and add a handful of new capabilities. These upgrades will make printer configuration much easier going forward. Here’s a quick rundown of what’s new:
