For those who want to have a heated bed and print with ABS, why not put the FSR's into a hot end setup?
FSR's built into a groovemount designed to be used with an actively cooled hot end, used as an autolevel calibration probe:
I am using a groove mount FSR setup I found on thingiverse: [www.thingiverse.com]. The slighlty modified firmware available here: [github.com]. This setup
uses two FSR's built into the groovemount and the tension can be adjusted with two springs. I am using a fan cooled E3D hot end, so the top of the heatsink should be relatively cool, and
not transfer too much heat into the plastic. This way, the hot end ittself is doing the probing. You can pre-load some of the resistance on the FSR's with adjusting the spring tension i.e. adjust some of
the sensitivity. I have not tested this out yet, so wish me luck......
