Development Status
Most marlin is applied to calculate the temperature accurately.
- Supports any number of thermistors, the only thing that limits you is the number of analog inputs your arduino card has
- The temperature output is in degrees centigrade.
Installation Instructions
- Using Arduino IDE
- Clic in green Clone or download button.
- Select download as zip.
- Follow this instruccions: Instructions for Windows or mac
Issue/Bug report template
Before reporting an issue, make sure you've searched for similar one that was already created.
Example with ramps schematic
Supported thermistors
All definitions in src/Configuration.h file.
Example configuration
- #define TEMP_SENSOR_0 80 // This is thermistor 0
- #define TEMP_SENSOR_1 0 // This is thermistor 1
- #define TEMP_SENSOR_2 0 // This is thermistor 2
- #define TEMP_SENSOR_3 0 // This is thermistor 3
- #define TEMP_SENSOR_4 0 // This is thermistor 4
- #define TEMP_SENSOR_BED 80 // This is not used thermistor
At this example we asigned to therm0 80 ( 3950 thermistor 100K - 4k7 Pull up and 10Uf Capacitor )(RAMPS STYLE).
In basic example selected thermistor is PIN A0 and therm0 (thermistor therm1(A0,0)).
therm 1 is an 3950 thermistor connected in A0 pin with 4k7 pullup and 10Uf capacitor to GND.

0 : not used -
1 : 100k thermistor - best choice for EPCOS 100k (4.7k pullup) -
2 : 200k thermistor - ATC Semitec 204GT-2 (4.7k pullup) -
3 : Mendel-parts thermistor (4.7k pullup) -
4 : 10k thermistor !! do not use it for a hotend. It gives bad resolution at high temp. !! -
5 : 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (4.7k pullup) -
6 : 100k EPCOS - Not as accurate as table 1 (created using a fluke thermocouple) (4.7k pullup) -
7 : 100k Honeywell thermistor 135-104LAG-J01 (4.7k pullup) -
71: 100k Honeywell thermistor 135-104LAF-J01 (4.7k pullup) -

10 : 100k RS thermistor 198-961 (4.7k pullup) -
11 : 100k beta 3950 1% thermistor (4.7k pullup) -
12 : 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) (calibrated for Makibox hot bed) -
13 : 100k Hisens 3950 1% up to 300°C for hotend "Simple ONE " & "Hotend "All In ONE" -
20 : the PT100 circuit found in the Ultimainboard V2.x -
60 : 100k Maker's Tool Works Kapton Bed Thermistor beta=3950 -
66 : 4.7M High Temperature thermistor from Dyze Design -
70 : the 100K thermistor found in the bq Hephestos 2 -
75 : 100k Generic Silicon Heat Pad with NTC 100K MGB18-104F39050L32 thermistor -
80 : 3950 thermistor 100K - 4k7 Pull up and 10Uf Capacitor 1k ohm pullup tables - This is atypical, and requires changing out the 4.7k pullup for 1k. (but gives greater accuracy and more stable PID) -
51 : 100k thermistor - EPCOS (1k pullup) -
52 : 200k thermistor - ATC Semitec 204GT-2 (1k pullup) -
55 : 100k thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (1k pullup) Use these for Testing or Development purposes. NEVER for production machine. -
