    I needed to buy a replacement quickly for the Thermistor for my hexagon hotend. I know they use a 100k Thermistor, but I not sure what type? PLEASE HELP.

    Pretty much any type would work as long as you know what it is so that you can set the firmware correctly. That should be the same type as stock.

    Yes.

    No. I use the MetalStud type which is largely indestructible.
    Can't use it with the hexagon though. I only use E3D hotends.

    You can reuse the one they have since you have to desolder/remove the existing thermistor and resolder the new one on.
    Make sure you put the plastic sleeves on the legs the thermistor or it will short out on the heater block. Also heat-shrink over where the solder joint are. It should look just like it does now when you are done.

    If you go through Robo they might sell you one with the connector and soldered on already.

    I am sure EPCOS is a type 1 in Marlin and that is what Robo uses by default, yes:

    //// 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)
    // 20 is the PT100 circuit found in the Ultimainboard V2.x
    // 60 is 100k Maker's Tool Works Kapton Bed Thermistor
    //
    // 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_0 1 //robo

    Not likely unless Robo sells the one with the connector already soldered on.
    Call them. They have 24x7 support.

    You might want to google search your area where you live and see about finding some local MakerSpace or Maker groups. Then you can meetup with local folks who do this same sort of stuff and get help that way (and usually meet nice folks).

    I couldn't say. They are hardware (like home improvement hardware) people. This is more electrical/electronic work.
