    Heated Bed Stuff

    I have an MK 1 plate, and a Borosilicate glass plate, and a 12v dc 30A power supply.
    What else do I need?
    I want to be able to regulate the temps to the bed, and it has to be simple, and cheap.
    What kind of thermistor, and temperature controller, how about wire type.
    I also need a diagram to wire it to the machine bed.
    Any help and comment will be well received.
    HAPPY NEW YEAR !!!!!!

    Here's the heated bed wiring diagram. http://reprap.org/wiki/PCB_Heatbed What that attaches to will largely be dependant on what controller you get. The RAMPS 1.4 Airduno based controllers can be had fairly cheap, though they may not be suitible for larger NEMA motors. You will also want something similar to the thermistor setup shown here to tape to the bottom, that goes to your temperature control header on your 3d printer controller. not my auction, probably better prices elsewhere, but shows the parts required. 100K Thermistor Install Kit for Heatbed PCB or Heated Bed for 3D Printers | eBay

    To be clear, this will be a stand alone manual system.
    In my searches for information this always comes up. From the RepRap site, I quote,
    "the MK 1 is easy to install. Solder two 12 awg wires to the MK 1 and connect to your dc power supply. The board naturally pulls about 7-10 amps and heats to a stable temp. of 110 C. within minuets". At the end of a suggestion note it states "Resistors, LED's and a thermistor are optional". Each popular site such as Maker, Ultimachine, Lutzbot have the same information. I am assuming the board means the plate itself.
    But nowhere does it say how to connect the Thermistor to the bed plate.
    For my independent, stand alone system, I am using, a PID/SSR/K type Thermistor, to supply the monitored temp. power and control.
    Everything I've read says I do not need the LED's or Resistor. I will be using Mach 3 and Kisslic as control systems, with no other electronic service circuits

    Most just tape the thermistor to the bottom center of the heatbed with some kapton tape.

    But, the one I have has a threaded hex fitting, 10 mm x 12 mm long , sliding fit onto a shielded cable containing two thermal shielded wires. Can I try to remove that threaded piece and then tape it on?

    Taping it on would be the most ideal option. But make sure to avoid overlapping of the tape. For more tips: Black ABS Filament with 1.75mm Diameter - 3D2PRINT
