Had a problem for a couple of weeks. Have an Ender 5 plus, with creality direct drive extruder fitted. running the Tinymachines software / firmware.
When I’m testing using the refuel mode, my extruder just seems to “pulse”—you can feel it with your fingers. It won’t feed or retract.
I plugged in the old extruder (same result) and checked the wiring as best as I could, and couldn’t find any faults.
I have changed the cables (extension ones) - only cable I have not replaced is the one from the main board out.
Any ideas?
