I have an MKS Base 1.4 board with a TFT28 touch screen and a Titan Aero setup.

When I use the load filament command from the touch screen the motor turns at a crazy speed to load filament, whereas if I plug in my laptop and use Repetier host and send a load command it turns at a normal speed.

Is there a section in the Marlin firmware that allows me to set the actual extruding speed during load and unload?

• Please explain how you retract and unretract filament with Repetier Host. E.g. are you using the G10/G11 G-code commands?

// (mm/s) Unload filament feedrate. This can be pretty fast.
