@discip, try this, it works for me [Bigtree3DPlugin.zip](https://github.com/bigtreetech/Bigtree3DPluginSuit/files/6873572/Bigtree3DPlugin.zip)

I have Windows10 and Ultimaker Cura 4.9.1 and it works well. The plugin also worked in older versions of Cura. Did you copy the "Bigree3DPlugin" folder to the "plugins" folder?

How are you physically involved? X-axis - Engine 0 Y-axis - Motor 1 Z-axis - Engine 2 Z2 axis - Engine 3 E0 axis - Motor 4 If so, please...

If you eject the filament (activate motor E0) the motors Z will move? One, both or none?

I did not notice any errors in the configuration that would cause this problem. You can take a good look at the board, if there is no short circuit on...

If position motor 4 were shorted to the Z axis, you could remap the extruder to position motor5 in the pin set and use this position for the extruder....

More people have a similar problem See #54 #88

Send the photo plugged in. Have you used the right connectors?

Send a photo of the wired board. Send a photo of tmc2209 from the side of the pins

Check if the pins for UART mod are connected
