The last few months have been spent calibrating and tuning the four different temperature sensors available on Recore A5 and A6. To aid with the calibration, a dry well calibrator was created that is controlled with Recore and with results plotted in OctoPrint. Below is a video explaining how it was done. This post adds…
The development of Recore is moving along. The latest revision of the hardware is A6. The rate of change on the hardware development side of Recore is slowing down. That means it is almost perfect. The biggest changes from A5 to A6 are: External r_sense resistors for the TMC2209s. Better ESD protection for CE compliance…
There is now a new video out documenting how Recore A5 is tested and calibrated. This blog post will act as a supplement to the video, giving some more detail and offering the material as a readable reference. Functional testing The testing procedure for Recore is done by the board itself. This is convenient because…
The new 3D-printer control board (Recore) that was started in 2019 is now mature and ready to start shipping to customers. We are now at revision A5, but the A4 was also working fine, it was just a few minor tweaks related to testability mostly. But this blog post and accompanying video will be centered…
This calls for celebration! The Manga Screen 2 that was Kickstarted in August 2017, has finally been shipped out to the backers. All Kickstarter campaigns seem to get delayed, and this one was no exception. Manufacturing always has a tendency to take much longer than expected, and 9 months is not unusually long. The feedback…

The Kickstarter for Manga Screen has been postponed again and again, but now the first promotional video of the new screen is finally hitting the streets! It’s a trailer for the Kickstarter, showing one of the applications that it can be used for. The application is called Karma-button, an app for giving creds to others…
Automatic bed leveling helps improve first layer height above bed. That is very useful, because if the first layer does not stick, the rest of the print does not matter. It also lowers the bar for first times to get started, and it saves a bunch of time for old-timers that have moved their printer….
Redeem is quickly becoming the standard in 3D printer firmwares with self documenting G-codes and pre-processing path planner. Up until recently, two fairly standard features have had somewhat sub-par performance: PID auto-tune and automatic bed calibration. A recent poll on the Thing-printer G+ page revealed that these two things were on the top of list…
The instructions for flashing a BeagleBone Black has long been in dire need of an update, and that day has finally come! The etcher.io (Etcher by RESIN.IO) is a beautifully designed app that runs on Linux, Windows and OS X alike and it does one thing: Burn images to SD cards. Since Kamikaze is based…
