Solved Heated Bed Max Temperature Issue
-
Hello, ever since updating to RRF 3.01RC3 on my Duet 3, I've been having an issue where my max heated bed heater temperatures (there are 2 heaters and sensors) are not being set correctly. I try to set a temperature higher than 125 and the board spits out a temperature too high for heater error.
I have copied the relevant section of my config.g below.M308 S0 P"temp0" Y"pt1000" A"Bed Right Rear" R2200 ; configure sensor 0 as PT1000 on pin temp0 M950 H0 C"out7" T0 ; create bed heater output on out7 and map it to sensor 0 M143 H0 P0 S200 A2 C-1 ; set temperature limit for heater 0 to 200C M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit M308 S2 P"temp2" Y"pt1000" A"Bed Left Rear" R2200 M950 H2 C"out8" T2 M143 H2 P0 S200 A2 C-1 M307 H2 B0 S1.00 M140 P1 H0 M140 P2 H2Thank you!

Try moving the M143 commands for the bed heaters after the corresponding M140 commands. Either the M307 command or the M140 command is resetting the temperature limit.

Great! That fixed it, but now my Duet Web Control graphs go up to 2000 degrees for some reason.
Here's the new section.
M140 P1 H0 M140 P2 H2 M143 H2 P0 S200 A2 C-1 M143 H0 P0 S200 A2 C-1 ; set temperature limit for heater 0 to 200CAnd here's what my temperature graph looks like.
Thanks!

Please post your whole config.g file, also config-override.g if you use it.

@lee7670 I'm also facing this issue. Please see below for my config.g. Any ideas @dc42?

@cryptelli I suggest you go back to the online config tool and generate a config to compare yours against. The ordering of the heater commands for instance.

@phaedrux Yea. Ended up doing that, problem solved.
