Enable Heater 2 and Hot_bed

Recommended Posts

In stead of messing with the code of Marlin, I started to swap out resistors 4.7k ohm was what I have been using this whole time. I tried 10k with no better results.

With each resistor I recompiled the look up table with the Python script from Rep Rap

22k ohm works ! It starts off around ~ -20 only 2 less then the last value in the table {1008, -22}

47k ohm works as well but it starts around -44

Testing the 22k ohm resistor, Using my fingers to heat up the resistor It only returns a result of ~9c which means I should be dead.

But I don't care, its working with out messing with any Marlin Code and no need to pre-heat the resistor.

I'll be testing the results of the 22k ohm resistor at 60c, 70c, 80c, 90c, 100c with my toaster oven.

( I have one of reflow solder hacks that controls the oven's temp with an external micro controller)

Thanks for everyone listening and reading to my troubles,

Brian

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
