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...
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, ev...
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.
Hey 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...
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 v...
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:

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...

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.
