  1. Hi Daid, Ive print on additional 2mm thin acrilic plate so no problem with that!

    One more comment on "Build me marlin" builder- i could not invert EXTRUDER axis-it does not matter is there checked or unchecked box- it rotates in one direction always!!! so I finished reversing motor wires to reverse extruder motor! ;)

  2. But, is the tip thermo isolated from the steel part in the bowden tube?

    Now it is not isolated, I suppose that contact spot between tube and steel fitting is so small that it should not cause steel heating enough to melt filament above it but anyway I need to do some tests at first and if the problem appears I can make PTFE insert between steel and brass tip

  3. ... or you will be arrested for making weapons....

    Bwa-ha-ha-ha :lol: nice joke, almoust close to the true :mrgreen:

    Yesterday I've got a chance to visit my friend with normal not baby lathe, so improvisation continues,

    first of all we finished with "AUDI" bushings, so now they fits in to the wood perfect

    and then we made some parts for my upcoming hot end

    I decided to fix bowden tube little bit different way then the orifinal Ultimaker, so we made a special steel fitting for that

    I'll be more then HAPPY if somebody can measure some head sizes if it is not a secret :)

    One more question, how does the head work for you? Is it enough cooling of upper (cool) zone of the head, or it would be better to make additional heat sink or even cooling fan on the upper side of the head???
