Prusa Mini+ BMG dual drive extruder upgrade reduces clogging jamming troubleshooting mini M500

I'm no stranger to these Prusa Mini 3D printers. I've fixed at least 10 of them. The all come in with the same problem. Back pressure from the hotend overwhelms the singe drive extruder and cut a hole in the filament. Once the filament is damaged you have to take the extruder apart to fix it I've had good luck with these dual drive BMG extruders. They grab the filament from both sides reducing the chances of cutting thorough the filament . The BMG is extruder is a 3:1 gear ratio so you will need to change the esteps to 415. The Prusa does not allow you to use a M500 command to save the changes from the command line. I was able to go into adavnced mode and change it from there. You could also add M92 E415 to your start gcode
