Extruder motor not starting

[chillteen]

Hi,

I have the following issue : It beeps when reaching min temperature, fan is starting and puller motor starts but motor extruder doesn't. I switched the motors and the pins e0 with e1 to check if any issues with the driver on the ramps=> none. I use 3 jumpers on E0 instead of a switch and it shows E RPM Off when reaching temperature. Any suggestions ? Thank you 🗡️

I also get this when upload Mackerel 💯

to solve this problem you need to add this jumper
