Revision to Connecting thermistors or PT1000 temperature sensors

Tony

[code]M305 P1 X501 R4700 ; heater 1 uses a PT1000 connected to thermistor channel 1 which has a 4.7K series resistor[/code]
 
Note: '''PT1000 sensors connected to thermistor inputs have lower resolution than PT100 sensors connected via the RTDPT100 daughter board'''. The accuracy of PT1000 sensors should be very good on the Duet 2 Maestro and generally good on the Duet 2 Wifi and Ethernet. However, it may be poor on the Duet 06, Duet 085 and other SAM3X8E-based electronics.
