FSR Groove Mount

thingiverse

Groove mount using FSR (Force Sensing Resistor) for automatic bed leveling. Rather than placing FSRs under the bed as originally proposed (http://reprap.org/wiki/FSR), I decided to put FSRs on the groove mount. Two FSRs are placed between the two parts of the groove mount. This method allows to probe with lower pressure on the hot-end and can be used with any bed (even heated beds). I use springs to keep both lower and upper parts together and fasten them to the effector, which protects the nozzle against crashes. A demo video on my kossel:https://www.youtube.com/watch?v=wzcnmsPo-1o Instructions Put two FSRs on the bottom part in the holes provided for this purpose (I used epoxy glue). Assemble with the top part and fasten to the platform with springs (to protect the nozzle agains crashs on the bed). The FSRs must be connected in parallel to an analog PIN. You can use it with the fsr branch of Johann C. Rocholl's Marlin firmware https://github.com/jcrocholl/Marlin/tree/fsr or with my fork:https://github.com/Edlep/Marlin
