Robin Mini V2.0 Extruder motor not turning - new issue ? #178

Open jaymcd opened 4 years ago

jaymcd commented 4 years ago

I have a Robin Mini on a Kingroon KP3. The extruder stopped working after a I had a filament jam. The extruder motor turns on other driver ports ( x /y ) but the E port seems to no longer work. I can't tell if this is an electrical issue ( i.e. E driver burned out). Nothing evident on the board suggesting this. Is there a way to test the E driver other than plugging a motor in? Everything else on the board seems to work. ??

also - the D3 led light is on - stay on as a red light. Is this normal or indicative of a problem.

Hi! Test the extruder method, the temperature of the extruder's heating head reaches above 170 degrees. You can control the rotation of the extruder D3 is 3.3V power led

Thanks. It doesn't turn even with the extruder preheated. No apparent markings on the board that would indicate the Shelley driver is damaged. Would a jam cause a motor driver to burn out?

Is there a way to test signal coming from the driver?
