Here's the problem I'm having with Marlin and a clay paste extruder .
My geared stepper motor running the extruder pump seems to be giving out when I reach hi steps per mm on the feedrate and or flowrate . The main stepper motors slow down and skip , and the extruder motor skips and hums? This is with no load on the extruder stepper, and the Voltage is set correct.
Here is my setting for the stepper motor drivers and firmware EEPROM
