    I'm trying to work with a filament that has an extruding temp of 170c to 180c but my printer won't even attempt to feed filament below 190c the parts are actually coming out fairly nice but i wanted to see if they could be improved upon especially when printing taller prints as 190c makes the material a little soft how do i get the extruder to run at lower temps?

    You need to edit the firmware and reduce the minimum temperature limit (in CONFIGURATION.H) if you want to print that cold.
    I do, because I have a Volcano adapter and it lets you print colder... I think I have mine set at 165 or 170.

    http://guide.robo3d.com/Wiki/ROBO_3D_Firmware_Release_Notes


    Min and max are in this snippet:

    #define EXTRUDE_MINTEMP 185


    // When temperature exceeds max temp, your heater will be switched off.
    // This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure!
    // You should use MINTEMP for thermistor short/failure protection.
    #define HEATER_0_MAXTEMP 290 //robo
    #define HEATER_1_MAXTEMP 275
    #define HEATER_2_MAXTEMP 275
    #define BED_MAXTEMP 110

    My bad the initial snippet I posted for MINTEMP was incorrect.
    The above are correct now.

    I inlcuded MAXTEMP just so you can see where those ar eset as well.
