  1. Found a house with space for a studio. Been a long 3-4 years with little to no pottery ;[

      Looking forward to being able to post some stuff here again :D  Few months and I should be set up. Have two weeks off work the end of next month as the factory is shutting down so plan to be moving in by then.

      Isn't it nice when a factory shut down works to your advantage.    The company my husband worked for shut down at Christmas for two weeks every year.  Most people used some of their vacation time,  one year they shut down  for over a month.  My husband was promised a job when they reopened  so we decided to take a long vacation in New Mexico and Texas.  We did a no maps, reservations, computers  trip and the areas we were in didn't have cell phone service.   We found ourselves at the strangest little towns and tourist attractions.  Now that he is retired I hope to do it again.   Denice

  2. A lot to me is just more than my old commercial kiln would click the relays. I am using mechanical relays so I guess it is much easier to hear it. Do you think as long as you can keep it cool then there is not much to worry about with SSR's? In this picture you can see my test, it does wobble a little on the climb so could be much better but it is pretty close. It does get worse as it goes up and I have never tested past 900c so some tuning is needed. I just had no idea how so bodged this way. The big rise/drop is because I didn't code going from on for 60's to off for 60's right and it stuck on so I pulled the control wire. That setup was one big safety issue in the corner of my bedroom. Only tried once, it gave me a headache.
  3. I read a few things on pid tuning and was very confused on what to do, the one you posted looks a little easier for kilns specifically. I just ended up using the pid code to read the temperature difference from setpoint + actualtemp with p=1 i=0 d=0. Does 2 seconds not get the relay to cycle on and off a lot? Maybe that has a lot to do with my pid use I ended up deciding every 60 seconds if the power should be on for 1/6th of the 60 seconds up to 6/6th. That got things to work pretty well and only turn on and off once in 60 seconds.
  4. The only rule I can find says information is presented at your own risk.
  5. Are you deciding if you should turn the relay off or on every 2 seconds? How did you come up with the PID values to use?
  6. In Shanghai airport on my way to Australia for Christmas and the only thing that I can seem to access is this forum ;D. Not blocked by their fire wall.

  7. Here's the MAX31855 circuit diagram if needed. I also have a board layout but probably cheaper to just buy the module from adafruit
  8. I found sometimes the MAX31855 spits out NAN when reading the thermocouple. Were they the kind of errors you were getting? @jbruce Have you seen the MAX31856 chip that can be used with all thermcouple types? https://www.adafruit.com/product/3263
  9. Was there an issue with element corrosion? People always say it is a bad idea to combust things in electric kilns but I dunno how many have actually tried. I would be interested in the story.
  10. I hope you find a good job,  I have looked at two different pottery jobs in the past.  One paid by the piece,  it was mostly slab work.   The other was a job to make slip mold originals.  Neither of them paid a living wage  and required a lot of driving.   We don't have very many pottery factories in Kansas.  I am sure with all of the potteries in Stoke-on Trent you will find the perfect job.    Good luck.    Denice

  11. After 1.5~ years working as a receptionist and saving money I have moved to Stoke-on-Trent to find a job in a pottery factory :lol:

      Found a job as a belt attendant, lots of moving and stacking pots in the decorating department :lol: not the most exciting work but better than answering the phone.

      YAY! Fanfreakingtastic! Best of luck to you.

  12. I find if I wiggle my head from side to side they can appear from the glowing mess as your brain picks up the outline of the cone. No easy answer, they are just difficult to see. Do you use any welding glasses for eye protection / decrease light and make it slightly easier.
  13. Ok, if it is saying 10psi input I guess that should be for propane. I don't think natural gas ever comes at 10psi. The only reason I was worries is if you are supplying the burners with a low pressure they wont get 60,000BTU as that is related to the size of the burner orifice and the pressure of gas you are supplying. I had no issue using a single control valve before a flat regulator on a 4x burner gas kiln. Actually found it much harder to get an even turn/twist on each burner.
