@deckingman Holy crap! ok, thanks. I guess I should RTFM.

@deckingman Ok, this is making more sense now. If I throw "T0" via console in DWC or S3D then selecting temp in GUI works. Am I just missing a button to select a tool in the DWC. I can click Heater 1 link and it cycles from active to stand by to off and then loops. I guess that is what needs to be done via GUI. Deckingman, I will put T0 at the end of my config.g file like you suggested, that makes sense.

Thank you all for the interactions and advice. Perhaps there could be some tweaks done to the DWC GUI, but it is just more me learning it.

Ok now how do I mark this as solved??

@bricor I am not experiancing what you are exactly. I am not able to set the temp in the Graphical User Interface of DWC and have the hotend start heating. I can set the bed temp. It doesn't matter if the bed is to temp or not I cannot set the hotend temp. I can only set the hotend temp via the console. If I use the Simplify3D console I have to send "T0" then the GUI buttons work.

OK so if I throw "M104 T0 Sxxx" via the console in DWC or S3D hotend comes alive. In DWC both the active and stand by temps are set to the target temp. In S3D both the Set and Off buttons function correctly. So how do I get S3D to work correctly from a cold boot of the printer without having to first send a command via console, and how do I get DWC GUI to work?

Sorry if I sound dumb, but I am just ignorant. I sent "T0" in both DWC and S3D and then tried to set hotend temp. Nothing happened.

In S3D or in DWC?

Short sweat background / config. I have a new Duet 2 Wifi, Duet Web Control 2.0.4. I have a CoreXY machine. I have an E3D v6. The hotend does heat up. The heated bed has no issues.

When attempting to set the temperature for the hotend in the Duet Web Control (DWC) it does not activate the hotend. I have attempted with the drop down's preset values, I have tried typing in my own and pressing enter. I am able to get the hotend to start heating by issuing a console command, i.e., M104 H1 S245 (this is the most reliable method) or by going to the "Control All" menu and setting a temp in the "Set all active temperatures" (this also hits the heated bed setting and gives an error that 245, etc. is too high for this heater - this is to be expected). When typing the temp I want into the hotend active temp I sometimes get a message to type in a valid number, again I am typing in 245 or 250 or 190.

I also have Simplify3D so I connected that via USB to see what it did. Long story short I kind of get the same problem accept I cannot use the M104 command, nothing happens. I set the temp and tool to T0 then click "Set" button, nothing, I then change drop down to T1 and without doing anything else the hotend pops on and heats.

I have not setup my panel yet so I haven't tried that method.
