Okay I'm looking at the gap you say I should have there. Now my brass pipe is fully threaded in as it should be To compare I have a spare hot end kit. Apart and assembled are just like what I have installed.... image.jpegimage.jpeg Hi LePaul My 2 cents if that can help ! your pic shown the Peek scr...

Hi LePaul
Why not? I would love to do it !
by cons, very hot! transportation costs

Izzy !!! some restraint please !
I am a little ashamed of the chaos in the workshop

Thanks ! you are so kind
I would not want to make false modesty, I only operate all my experience gained during 30 years in the mechanical.

you're going to say I have all the answers

In addition to the 19mm linear/rot. bearing of the slider Y , this one is completely integral with the slider X in rotation through 2 flanged bearings

no problem it exists linear/rotating bearings

In reflection mode may be a dual tilting/lifting print head !?

my crazy home workshop

Thanks to you !
I do not count my time, I took early retirement last 7 months, I have all my time
the largest time is spent in reflection and CAD drawing, it's 90% of the work done, and then after when machining that is really relaxing !

Hi to all Sorry to monopolize the post, it's just a willingness to share! :oops: I'm still in my trips of print head :shock: Originally before finalizing PBI print head, I drew this one, and I am back on this project while I am satisfied with the results of PBI project, This one may be easier and le...

Gudo, i have some thoughts about your print head, it looks like you have copied the aluminium heat sink designs and i belive you are going with way too many and too long fins, since the PBI has so low thermal conductivity the upper fins and the outer edges of the fins will never get hot, you could ...

Hi to all I'm still in my investigations concerning the use of PBI I tested especially with the PLA filament, to understand the behavior of the polymer Everything goes well except that I foolishly broke a coupler by overtightening the heat block, :evil: http://nsm08.casimages.com/img/2016/07/13//160...

I like the rigidity solution idea Thanks! I do that for my print head project, it's will be a bit tricky with the UM2 stock print head because of there is not so much space at " home position ", risk of collusion if raise the bed ! needed to make the supports in a flat piece of high grade...

That is very impressive gudo! I am particularly interested in the experiences with PBI since it has potential to permanently solve the PLA issues with no drawbacks. Did you try printing other materials than PLA yet? Thanks Anders ! This polymer is really very promising for 3D print , thanks to its ...

Hi Neotko , thanks !
We play with a very small layers thicks, 0.25 , 0.4 .... so I think that any improvement in the motion would be good for the print results, may be I'm too much perfectionist
