unable to extrude despite at temp

ageis

So I have the hotend at 215 and the bed at 65.

But the extrusion controls are disabled. Usually in the old firmware I can extrude around 180.

See screenshot!

Here is my config: I dont have any filaments defined in the filaments section

@ageis activate the tool by sending T0

best to add T0 to the end of your config

deckingman

@ageis Try what @jay_s_uk said first, but from your screen shot, it looks like the tool was indeed active. If that is the case, then the command which controls extrusion temperature is M302. According to the docs, it should default to 160 for extrusion and 90 for retraction using the S and R values respectively. Try sending M302 without any parameters to see what gets reported back. If it's something other than 160/90 then look for an M302 elsewhere, for example config_override.g or perhaps in the slicer start code or a macro that you might have run prior to attempting to extrude.

Thanks Jay it seems to be working now.

Maybe it needs to be fixed in the reprap config tool. I am very sure I used it because I upgraded from a very old version of the firmware to the latest. I remember generating a new set of config files based on an older config.

droftarts

@ageis There's an option in the config tool to select the first tool on startup, which is not on by default. It adds T0 at the end of config.g.

Also, the commissioning guide explains you need to enable the tool to extrude: https://docs.duet3d.com/en/How_to_guides/Commissioning#h-6-check-heater-functionality
When the tool is active, it will be highlighted blue in DWC. The heater can be active, even if the tool is not active.

Ah good to know. I wasn't aware of that.
