Marlin: E1 Heating failed. Marlin 2.0

[blueeagle69]

Since moving to my SKR 1.3 and Marlin 2.0, i'm getting a lot of E1 Heating Failed messages, with only E0 enabled.

It normally happens when the the printer is heating and I home the printer.
I've tried with #define PROBING_HEATERS_OFF enabled and disabled, but I'm still getting it.
I've attached my configuration files.
Hopefully this will help.
Thank you.

I'm having a similar problem. I am running a SKR 1.3 and Marlin 2.0 on an Ender 3.
When I try to heat for a print with a target temp of 200 it waffles between ~188 and ~195 a couple times, then gives E1 heating failed. I only have one extruder enabled.
Config files also attached.
Thanks!

I will have an SKR 1.3 for testing soon, so I can test the thermistor readings at that time.

I was actually able to solve my issue in the past couple hours. The error saying E1 heating failed is an unfixed text error according to #12625 and should say E0.

As for the heating issue (at least my heating issue) I found this post on stackexchange recommending calibrating PID values. I found instructions here and entered the resulting values into my firmware and the problem disappeared.

Marlin has always displayed "E1" to users for the first heater even though internally it refers to it as "E0."

Good to know. I’m new to Marlin (as of today, although I spent like 10 hours getting it to work) so that post was all I had to go on.
