Error: Heater 0 fault: temperature rising too slowly
-
Whenever I start my bed heater I get Error: Heater 0 fault: temperature rising too slowly: expected 2.30°C/sec measured 0.57°C/sec
How do I change this value? Do I need to change the heater?
This is a 120V bed heater running through a solid-state drive. It is giving 120V to the heater.

Perhaps this is a "PID Tune" issue, and if so, how do I do that?
-
Sry, this was too easy and I gave up before I needed to. I found this code and am running it now...
m303 h0 s100

@the-chairman If this doesn't fix the problem you may have to tune it manually. If so see "Setting the Model Parameters Manually"
-
@jrcl Thanks... I think I missed a "u" argument which would have used the result, so I might have to rerun it or go your route.
-
@the-chairman That is for Marlin firmware and you are using reprap. To my knowledge the U argument is not supported by Reprap 3.3. While both based on G-Code they have some subtle differences so try and use this g-code dictionary as much as you can!
There are a few choices when manually tuning but to my understanding using R, C, and D are the easiest as you can calculate them with a stopwatch and Duet Web Control (DWC).

@jrcl Again, thanks. It has finished the auto-tune and gave me this message:
Auto tuning heater 0 completed after 3 idle and 5 tuning cycles in 998 seconds. This heater needs the following M307 command:
M307 H0 R0.532 K0.167:0.000 D13.56 E1.35 S1.00 B0
Edit the M307 H0 command in config.g to match this. Omit the V parameter if the heater is not powered from VIN.I didn't see a "V" parameter in that line of code and am not sure what VIN means in this context, in any event. I easily found the line of code in my config.g and have replaced it.

@the-chairman I'm not an expert but this would be used if you used the VIN terminals on the board to power your bed, which you would know. Seeing as you're using a 120V bed with an SSR you probably aren't using those.
-
@jrcl Does VIN stand for Voltage In, then?
-
Thanks to everyone here the printer is printing... I am waiting on terminals to finish the CR Touch install and I'm pretty much ready to play with it.

@the-chairman Typically but the scope in which it applies can vary
