    on with a built in laser pointer would be cool. Particularly if you still had working eye muscles and could actually aim it by looking at something.

    one scenario.

    bear in mind that the x gantry is pretty much always going to be slightly higher on the side with the screw and motor than on the side that just has wheels (it's one reason to...

    print slower and increase retraction length and speed.
    You've got a direct drive extruder so you can run retractions at up to 70mm/s quite happily.
    Retraction distance wise start at about 2mm and...

    Right so, looking at it, it's basically...

    work on the principle that the power supply for most 3d printers is somewhere between 100-300 watts.
    I've rarely seen anything over 350 watt listed in a speification.

    hmm, odd, it's only in the one direction.
    have you tried either using a different slicer, or changing the infill direction settings ?

    Plus if it's a creality machine - which one ? Could be an...

    well just built a new machine for a client - so I'll try it on that one as well :-)

    What speeds are you printing at ?
    pet-g hates speed. anything over 40mm/s is really too fast.

    sounds interesting - I'll have a look.
    The printer is a fairly basic mini delta.
    Doesn't even look like it's even got a heated bed.

    So no, you really don't want to buy it :-)
