Ok. Glad that worked for you. Ill can't recall why I chose 13 which is why I left the comment there. Most of the example configs I found (1, 2, 3, 4, 5) used 1 for default.
In my case my resistors for R4 and R5 are labeled 1002. I never found that info when setting the thermistors initially. I guessed and used the best guide around I could find and saw that a majority of people were using 1 (default) or 13 but nobody chose 11. If that bug report is the latest and greatest I'll update the blog post in a few days and include this information. It appears I'll have to change mine to 99; however, it's printing fine now so I may leave it.
Edit: Should I also choose the bed as 99 in my case instead of the 11 I had it set for?
I won't close this immediately.
Nope Its always 11 because the skr 1.4 board uses 472 resistors giving it a 4.7k pullup and the wanhao i3 thermistor is a 100k 3950
You mention in your config that you aren't confident in your thermistor settings. Have you had success with the values that you use here?
There was some helpful information in this bug report regarding how to tell what thermistor you have.
On my Melzi, my R4 and R5 resistors are labeled
472
so I was told to select a "thermistor with a 4.7k pullup, probably a type 11" which is documented as being for most Wanhao i3's. You used type 13 for one of yours.Anyway I did a test run today and tried warming the bed up to 60C. It got to 52C then struggled to climb harder, so I think it triggered thermal runaway protection. Not sure what to check next. The temperature matched a reading from an IR thermometer pretty well, so it seems more like a power issue than failure to measure the correct temperature.
Edit: Second test was successful with type 11 thermistors.
