  • In my experience the hole that the thermistor goes into isn’t in the path of the filament. So probably what’s happening is either the nozzle or the tube that screws into the other side of the heater block is loose, allowing melted plastic to escape through a place other than the tip of the nozzle.

    After you’ve cleaned it out, what I like to do before running filament through again is to turn the hot end on, let it come up to temp, then tighten the nozzle a bit more. The joint expands when heated so even if you’ve got it right at room temp it can still need tightening at the working temperature.











  • +1 to the skipped steps discussion. Those offsets are from the print head somehow getting stuck and not moving when the stepper driver commands a move. Reasons can vary but often they are mechanically related.

    One very basic test is to move the head with your hands through its entire travel range on both axes (with motors off ie M84 or printer off) and feel the resistance to motion. Steppers of this size are not particularly powerful; you can overcome their force with your hands.

    Another possibility is that the acceleration is set too high: a fast direction change puts a lot of force on the motor. Try setting your acceleration really low, like 100, in the slicer and see if it still behaves that way. If not then there’s your handle on a parameter to tune.

    The poor behavior in the toast is probably a different parameter that needs tuning. I suggest getting the layer shift problem fixed before worrying about anything else.
