Heater 2 disappears in Web Control after connecting
Using the configuration tool I have added a second heater that I want to use on 1 extruder (it's a pellet extruder).
Before I connect to the printer the second heater is visible but when the connection is made it disappears.
Seems that the board is sending something back saying something is wrong?
Please some help.
@leonknook only the heaters/tools that are configured will show up in DWC. Please can you post your config.g
This are my settings in the config file, as generated from the configurator but what is wrong.
Playing yesterday with the tools I could get everything ok with pid-tune and all, but today when I started that was all gone again. I did use the M500 to save the new situation in the firmware but it doesn't come back.
M305 P0 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120 ; Set temperature limit for heater 0 to 120C
M305 P1 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 1
M143 H1 S280 ; Set temperature limit for heater 1 to 280C
M305 P2 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 2
M143 H2 S280 ; Set temperature limit for heater 2 to 280C

What you see before you connect to the printer is the default layout before DWC reads in the configuration file. That layout happens to have heater 1 and heater 2, which is why you see it initially. To get a heater to show up on DWC, you have to assign it to something (usually a tool) which kind of makes sense because unless it's assigned to something, it can't be used.
So for example, if it's to be used on tool 1 and tool 1 also uses a second extruder you'd have something like M563 P1 D1 H2. Alternatively, if you only have one tool (tool0) but want to use both heaters, you'd have something like M563 P0 D0 H1:2
As Ian says you need to allocate the heaters to tools to see them in DWC.
Thank you all for the help. I will be back later on this. I'm totally stuck on the whole board. Wifi does not work anymore at all. Past day's there where many disconnections. M20 does not show files nothing. M21 says sd card mounted and OK. Because the board can't read files I get a rejected HTTP request. Replaced SD card for a new one, nothing. It seems all so simple working with this board, the configurator and what not. I red somewhere in the forum that if you can't read files the sd card reader is damaged, please replace the board. I think I will do that on warranty, so much lost time, should be 15 min work not more.
@leonknook if you connect to it via USB using a terminal program like YAT and send M122 with the SD card inserted it should have a line with the SD card status. Please report that here.

I received a new duet wifi and everything works fine. The sd card reader was not functioning.
In an other thread new problems with the router I used. The card is fine.
