• 🔹 Heater Assembly – Efficient heating with safety measures

• 🔹 HMI Module – Interactive display and button interface

Electronics & hardware kit;

Electronics are easy to use and are the way-to-go for a plug-and-play system. However, they are expensive and only cost-effective in larger quantities. Therefore, I worked together with Blurolls store to offer kits worldwide for a price lower than you can source yourself!

Currently, we only sell through the direct store of BLUROLLS, but later we will also stock the kits in the USA and Germany, and sell through AliExpress.

Remixing;

I encourage you to play with the designs and code to add whatever you find missing for your setup! Some Ideas I have already seen online are mounting for MK/XL/Mini enclosure, different (touch) screens, print removal via the servo, or added functions on the OLED/ buttons. 

You can find the full source code in the files below, along with the PCB schematic and pinout. If you have adapted something, please make sure to post it as a remix for others to find! :)
