Work with Ender 3? #7

Closed scubieman closed 5 years ago

scubieman commented 5 years ago

I tried using this with ender 3. The park button works but the unload and load button does not.

I did try preheating the nozzle.

It works on my CR-10S so I don't see why it wouldn't work there. It's all standard Marlin stuff.

If you switch to the terminal tab after clicking the button(s), do you see any errors there? You may have to suppress temperature messages on that tab to see anything useful. Maybe open the UI up in two browser windows so one can watch the console while the other clicks the button.

I'm not sure what your firmware considers "too long" for an extrusion. The default unload length is 500 and the default load length is 50. If neither button works, then even 50 might be too long.

In the settings for this plugin, try using a smaller unload and load length. Start at 25 or so and work your way up.

You could also try an alternate firmware like TH3D UF to remove that unnecessarily low limit.

I don't see that this could be a bug in the plugin, so I'll close this for now, but please do follow up if you find some settings that work for your printer.

Jim. I know closed.

Found that this one only allows 200 MM of extrude/extract. but 400 MM of filament is in the tube. So I need to run twice. Just a FYI.
