I am still without a third FSR for my auto calibration Z Probe system! I need 3 because 3 points define a plane and also that is what my heated bed rests on, I have the FSRs installed with a quarter inch rubber foot on top of it as an insulater and it also acts to direct pressure to the correct area of the FSR.

At the moment money is tight and I cant afford to order a new one..... hopefully soon so things can progress on the RosBot-Kossel!
