jcosmo 5 Posted September 9, 2015 in Marlin Temp sensor setting for Ultimaker Original Heat bed Hi, I'm fiddling with custom firmware for a slightly altered Ultimaker Original. The UMO has the standard Ultimaker Heat Bed upgrade installed and if I upload the 'standard' firmware included in Cura 15.04, then the heat bed functions correctly. I've not yet managed to find what the correct TEMP_SENSOR_BED setting should be to build by own firmware that will work. Any hints? //// 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 (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 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (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) // 71 is 100k Honeywell thermistor 135-104LAF-J01 (4.7k pullup) // 8 is 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) // 9 is 100k GE Sensing AL03006-58.2K-97-G1 (4.7k pullup) // 10 is 100k RS thermistor 198-961 (4.7k pullup) // 11 is 100k beta 3950 1% thermistor (4.7k pullup) // 12 is 100k 0603 SMD Vishay NTCS0603E3104FXT (4.7k pullup) (calibrated for Makibox hot bed) // 20 is the PT100 circuit found in the Ultimainboard V2.x // 60 is 100k Maker's Tool Works Kapton Bed Thermistor beta=3950 // // 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) // 55 is 100k thermistor - ATC Semitec 104GT-2 (Used in ParCan & J-Head) (1k pullup) // // 1047 is Pt1000 with 4k7 pullup // 1010 is Pt1000 with 1k pullup (non standard) // 147 is Pt100 with 4k7 pullup // 110 is Pt100 with 1k pullup (non standard) #define TEMP_SENSOR_BED ????WHAT????

jcosmo 5 Posted September 9, 2015 in Marlin Temp sensor setting for Ultimaker Original Heat bed I think I've answered my own question - seems that a '20' is what I wanted. For some reason I had in my head that a 20 was associated with the UM2, not the UMO, and had disregarded it. 1 Share this post Link to post Share on other sites
