Description
Unfortunately I couldn't find a spool holder with load cell that fits to the holder of my 3D printer (Ender 3 S1 Pro). I don't know if this design also works on other printers.
I use a HX711 with 12,7x12,7x75 mm load cell (i use the 10kg load cell but any should work) and three screws (M4, 10 - 12mm). Because I created the holder with data from the internet before the components were delivered, there is also an 80 mm version.
I also added a holder that can be attached to the middle section to store the electronics.
Full code for integration the spools into Home Assistant via a Weemos D1 mini and ESPhome at "esphome_code.txt". The code needs a few custom settings at the beginning.
Component list:
1 x DHT11 (to measure humidity and temperature in the printing room)
2 x HX711 (to measure two spools)
1 x Relay Module (to control the light on the printer)
1 x Button (to switch the power supply (tasmota))
if you need further information leave a comment.
Thanks for the files that I could use for this remix.
