Here’s a neat trick for your next 3D-printer build or retrofit: a Z-axis sensor using a DIY strain gauge made from SMD resistors. We’re betting it could have plenty of other applications, too.
Out of curiosity, I bought a strain gauge sensor module after it appeared on sale. This write-up is fuzzy, since I decided to write based on a quick inspection of it. Have fun reading my little post ...
Strain gauge sensors measure the strain (displacement) of an object under an applied force. When they are adhesively attached to the object under stress (an applied force), they deform with the object ...
