Z probe with FSR

Hello,

I tried to implement a Z Probe with FSR. But FSRs have analogical signals. Do you think I could use Thermistor Pin ( Hotend 2-Pin 0.23 ) to get the signal ?

If not how to implement FSR for an endstop pin ?
Thanks a lot.

Have a look over at the delta printer google group. There’s lots of information about using FSR for calibration.

Some people seem to be using an ATtiny85 to process the analog signal from the FSR and then output a digital signal to the Z-Probe connection. The ATtiny also runs software which works to calibrate the FSR at startup so as to avoid false readings.

Hope this is of some help.
