The imminent 3.2beta release of RepRapFirmware includes support for filament monitors connected to Duet 3 expansion and tool boards. This post describes how I added filament monitors to the two Hemera tools on my E3D Tool Changer.
Since building my first Hemera tool controlled by a Duet3D Tool Board, I have built a second one and made some improvements.
My large Kossel variant has been running for several years now. It is reliable and produces good prints. I have however replaced the extruder drive and the power supply by different models, and added a filament monitor. I will now … Continue reading
