+//--NORMAL IS 4.7kohm PULLUP!-- 1kohm pullup can be used on hotend sensor, using correct resistor and table
+//
 //// Temperature sensor settings:
 // -2 is thermocouple with MAX6675 (only for sensor 0)
 // -1 is thermocouple with AD595
 // 0 is not used
-// 1 is 100k thermistor - best choice for EPCOS 100k
-// 2 is 200k thermistor
-// 3 is mendel-parts thermistor
+// 1 is 100k thermistor - best choice for EPCOS 100k (4.7k pullup)
+// 2 is 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup)
+// 3 is mendel-parts thermistor (4.7k pullup)
 // 4 is 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !!
-// 5 is ParCan supplied 104GT-2 100K
-// 6 is EPCOS 100k - Not as accurate as table 1 (created using a fluke thermocouple)
-// 7 is 100k Honeywell thermistor 135-104LAG-J01
-// 8 is EPCOS 100k - 1Kohm RESISTOR PULLUP ONLY! SEE therm table, should give twice resolution from 150C to 200C - EXPERIMENTAL!
+// 5 is 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan) (4.7k pullup)
+// 6 is 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup)
+// 7 is 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup)
+//
+//    1k ohm pullup tables - This is not normal, you would have to have changed out your 4.7k for 1k 
+//                          (but gives greater accuracy and more stable PID)
+// 51 is 100k thermistor - EPCOS (1k pullup)
+// 52 is 200k thermistor - ATC Semitec 204GT-2 (1k pullup)
