just curious, what is this?
I love motors and sensors

FSR's are resistors that change their value depending on the amount of force applied to the central area. I use 3 of these in a tripod formation under my bed to implement auto-levelling of the bed. See this video that shows exactly what occurs:

Cool, thanks, I wasnt able to visualize what you had meant by actuator, I see the contact point now. Makes sense in context. Auto leveling is great. I did CNC work a ton in the past. With my replicator I just get it close enough and then create a raft to build from. Seems to level work well with pla. But its a nightmare with ninjaflex, a level bed is essential.
Thanks for contributing. I have a good collection of FSR's, nice to see them put to use.
