Questions
How big is the FilamentMonitor PCB?
It measures 22 × 16.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FilamentMonitor use?
25 parts, built around the TCR2EF19,LM(CT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the FilamentMonitor KiCad files?
From the Duet3D/FilamentMonitors repository on GitHub, at the commit this page was made from: the board is Filament_Monitor_Laser/Filament_Monitor_Laser_v2.0/PCB/FilamentMonitor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FilamentMonitor design in my own project?
Its repository states no licence, so its author keeps all rights: ask Duet3D before reusing the design.
