Overview

I'm building an arduino based kiln controller for driving our Kiln.


Goals/Features

  • Add mode button for Candling. (raise temp to 190F and maintain temp for 12 hours.)
  • Add mode buttons for Timed Firing (not sure how this might be useful, but then I know nothing of ceramic arts either. maybe glazing?)
  • Add mode button for Gradual Heating (slowly heat the kiln as opposed to full electric on.)


Materials/Links

Technical Details

  • Status: reading temp and displaying it on lcd display; I'm waiting on the SSR from ebay to start integrated kiln testing. The high fire Type K thermocouple arrived and is installed.


Usecases

1.Turn On / Clear

  • Press Init Button

2.Select Cone

  • Starts at 022 and goes to 8

3.Select Hold Time (mutually exclusive with the physical cone switch)

  • 0 to 9 hrs

4.Select Kiln Mode - default is Fast speed

  • Press Mode Button to switch between Slow, Medium, Fast, Slow w/ controlled cooling, Medium w/ C.C. (back to slow)
Mode Time Segments Description
Fast 1 Balls to the wall/As hot as the elements can get
Medium 4 1(0F-250F@200F/hr), 2(250F-1000F@400F/hr), 3(1000F-1200F@180F/hr), 4(1200F-1700F@300F/hr), Further heating at 200F/hr
Slow 4 1(0F-250F@80/hr), 2(250F-1000F@250/hr), 3(1000F-1200F@150/hr), 4(1200F-1700F@180/hr), Further heating at 80F/hr
Slow w/Controlled Cooling 8/9 Heating cycle as Slow. Cooling is a reverse of Segments.
Medium w/Controlled Cooling 8/9 Heating cycle as Medium. Cooling is a reverse of Segments.

5.Start Button

  • Verifies all selections are valid and begins Firing Cycle.
