Solved Extrusion Options Extrude/Retract Greyed Out - Please Help

[Ripeds_O3P]

So I made the jump to DWC 3.4.0. Updated the firmware to the latest version. Updated the files as well.

Auto-tuned the nozzle and bed heaters. Updated the config file with the new lines (Nozzle example: M307 H1 R3.938 K1.379:1.484 D7.52 E1.35 S1.00 B0 V24.1).

Now the extrustion control options are greyed out (unusable) for extrude/retract when I hit 205 on the nozzle. It worked at 160 celcius on previous versions. And I'm at a loss on what the issue is.

Did I do something wrong during the PID tuning? This is probably a dumb question, but hey, I may as well have been born yesterday on the subject of firmware. Is the target temperature meant to push it to a high temp close to the limit of the heater to get good data from the sensor back? Or is the target temp the bare minimum that allows the extruder to function while also testing the sensor?

Or is there some other setting I messed up on? Another line of code that needs changing/defining after auto-tuning the nozzle heater?

I've quoted my config.g file below:

If it's easier to download and read, here's my config.g

@ripeds_o3p

If I recall correctly, I had to create and select a filament as well as select the tool by clicking on it in DWC. It puzzled me for a bit too!

You should also add a T0 to the end of your config.g to ensure a tool is selected at startup.

@phaedrux That fixed it! Thanks! ^.^

Added a note in the config to remind myself what it does.
