I just set up a Prusa i3 and is perfectly calibrated, the problem comes when printing for a few seconds and then stops printing materials extrude and again start printing...
Here you have a picture of the result. I've tried changing the settings, bed and extruser temperatura, the nozzle diameter (less diameter to extrude more filament), manually modify the current with potentiometer pololu, reduce all print speeds ... I can only set so that the amount of filament is greater but I do not know how. Any solution? Thank you.
