 ====== Jewelry Kiln ======
+This kiln is working, but has no active users, so we are in the process of learning its idiosyncrasies and making a proper doc.
+  * Model: unknown/custom electric kiln
+  * Controller: [[https://www.auberins.com/index.php?main_page=product_info&products_id=4|SYL-2352 Ramp and Soak PID Temperature Controller]]
+  * [[https://www.auberins.com/images/Manual/SYL-2352P%20Manual.pdf|Controller manual]]
+====== Tool anatomy ======
+{{:tools:jewelry_kiln:jewelry_kiln.jpg?nolink&600|}}
+. Controller
+. Breaker switches
+. Alarm lights
+. Temperature probe
+. Latches
+. Viewing port
+====== To do ======
+  * open & inspect electronics panel for safety
+  * order & install alarm buzzer-lights
+  * apply a better door seal
+==== 4/18 "does it work" test ====
+T value = time until next step
+^ Step ^ Set Temp (˚F) ^ T value ^ Check time ^ Check temp ^ Notes ^
+| 1 | 80 | 15 | 10:33 | 75 |
+| 2 | 300 | 15 | 10:48 | 295 | 213˚/15min = ~14˚/min |
+| 3 | 0 | -121 | 11:03 | 265 | it definitely works |
+==== 4/18 "is there an alarm buzzer" test ====
+  * AL1: Set ALM1 to 1000˚
+  * AL2: Set Hy-2 to 10˚
+Asked the kiln to try to ramp to 2k˚ in 15 minutes. The alarm relays are firing, but no alarm light or buzzer sounds, so we need to get one (or two).
+^ Step ^ Temp (˚F) ^ T value ^ Check time ^ Check temp ^ Notes ^
+| 1 | 80 | 15 | step skipped ||
+| 2 | 300 | 15 | 11:40 | 300 | AL2 light on, no buzzer |
+| 3 | 2000 | 180 | 12:00 | 550 | proceeding to "can we get to 2k" test |
+| | | | 12:03 | 600 |  |

+| | | | 2:32 | 1454 |
+| | | | 2:51 | 1492 |
+| | | | 3:45 | ~1570 | hovering around here, jumping rapidly up and down. the area around the kiln is warm. this is about the functional limit of this configuration. |
+| 4 | 80 | -121 | stop
+==== Forge curing schedule ====
+There's a forge which has been lined but needs to be heat-cured.
+^ Step ^ Temp (˚F) ^ T value ^ Notes ^
+| 1 | 100 | 60 | ramping up 100˚/hr |
+| 2 | 200 | 60 |
+| 3 | 300 | 60 |
+| 4 | 400 | 60 |
+| 5 | 500 | 60 |
+| 6 | 600 | 60 |
+| 7 | 700 | 60 |
+| 8 | 800 | 60 |
+| 9 | 900 | 60 |
+| 10 | 1000 | 60 |
+| 11 | 1100 | 60 |
+| 12 | 1200 | 30 | holding for 1/2 hour for 1/2" of material |
+| 13 | 80 | -121 | stop |
+The official kast-o-lite packet says to ramp down 100˚ per hour, but people online seem to skip this step.
+==== misc notes ====
+  * it's possible to store several simple programs; there are 30 steps total
+  * it's possible to set a schedule which is impossible for the machine to achieve
+  * telling people in plain english how to set alarms for each type of project is important
+  * the alarms don't stop anything and are not a safety feature so much as an alert
+  * it's possible to observe and change the schedule while it's in progress
