If that problem comes especially when retracting the fillet, there might be a problem with the upper part of the hot-end getting too hot thus melting the fillet too much. The fillet will expand when heated. When the molten material is then retracted in to the colder zone, it will solidify and can get really stuck. Especially if there are any gaps in the channel where it can flow in to and "anchorby AriS - Printing
Does it "dig" in to the filament, ie. does it try to feed the rod ? If it does, check the hot-end temperature and possible blockage. If not, try more pressure and check that the shaft is rotating when the extruder motor is running. BR. Ariby AriS - Printing
Hi Fujisama, Try measuring what your PSU gives out. It might give out 12V DC but not enough amps. This lead to a similar problem with my build, The chip will be powered from the USB, and seams to work but the motors require more amps. BR. Ariby AriS - Sanguino(lolu)

The ribbon cable connector was connected the wrong way in the Panelolu2 end. This got the Panelolu2 to work Secondly, i noticed that the regulator was giving a bit low on the 5V line (4,5ish), so I replaced the LM7805 which improved the situby AriS - Sanguino(lolu)
Hi Tony Thank you for the replay. The case is plastic, and as soon as I noticed the malfunctioning I took it out of the case and tried. With the same result unfortunately. I am quite shore that I also have the Panelolu cable right, but that is a good point. Normally things like these tend to be a result of user errors like this. I have tried with taking all connections out and examining the boarby AriS - Sanguino(lolu)
Hi! After installing the sanguinololu and panelolu2 in to a casing they stopped working and started to behave strangely.(Have been working properly prior to the installation) When powering on the board the LED lit up and the display backlight is turned on (might be a bit darker than normally), but no text. When pressing reset or control nob nothing happens. When turning the nob the display goesby AriS - Sanguino(lolu)
