Extruder Stepper not responding

mlbuxbaum123

I am having issues with my extruder stepper not responding to anything.
Board: Duet 2 Ethernet (2Ethernet)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.2 (2022-09-13)

I finally got x, y, and z to home properly, but now the stepper for the extruder doesnt move. Any ideas i should look into? Even in DCW the extrusion control menu is grayed out.

@mlbuxbaum123 post your config.
If the extrusion control is greyed out, do you have a tool selected?

@mlbuxbaum123 There are lots of possible reasons but with the very limited information provided, I can only make an informed guess. The most common reason is that by default, extrusion is prohibited until the hot end is heated. The next most common reason is that no tool is selected. The third most common reason is that the tool has not been configured to use the correct extruder drive. I could continue but you get the idea. For testing purposes, without any filament loaded, you could try sending M302 P1 via the console which will allow cold extrudes. https://docs.duet3d.com/User_manual/Reference/Gcodes#m302-allow-cold-extrudes

If that doesn't allow you to extrude, then you'll need to post your complete config.g file.

(This all assumes that you've checked the wiring and tested the motor).

how do i post config file the right way?

However, it is only possible to extrude the filament at a hot end temperature of 160°C. The retraction of the filament only from 90°C.
All that only when the tool is activated, i.e. click once on the name of the HotEnd in the DWC.
Before that, the entire function is grayed out.

-- Original Text --

Es wird aber erst bei einer HotEnd Temperatur von 160°C möglich das Filament zu extrudieren. Das zurückziehen des Filaments erst ab 90°C.
Alles dass erst wenn das Werkzeug aktiviert ist, also einmal auf den Namen des HotEnd im DWC klicken.
Vorher ist die gesamte Funktion ausgegraut.

You can also use the code snippet tool on the forum to make it easier to read. It's the </> symbol by Bold and Italic. Makes the code look like this

@mlbuxbaum123 config looks good. just add T0 to the end of your config on its own line

mlbuxbaum123

@jay_s_uk at the very end of the config file? Below the M911 S10 line?

jay_s_uk

@mlbuxbaum123 yep

deckingman

@mlbuxbaum123 Actually, your config.g does not look good.

This line "M563 P0 H1 F0 ; define tool 0" is missing a drive number. Try this

M563 P0 D0 H1 F0

@deckingman YES !!!!!! that worked ! Just had to reverse direction of that motor in the config file as well !! THANK YOU !!
