Building from scratch!

Recommended Posts

... 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

Interresting fix for the bowden tube. Looks like it could fix the plugging issue people are having.

But, is the tip thermo isolated from the steel part in the bowden tube? Else heat from the brass tube will also heat up the steel part, causing filament to melt above it, causing a plug.

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

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! ;)

Fixed it :) there was a bug, caused the setting to be always disabled.

a very big WOWW to your creation and the prints.

Congradulations you really did take on a big challenge and it seems like you have ROCK N ROLLED it to the finishing line !!

big congradulations.

Ian :-)

ps. if you have a minute, can you copy your new print photos onto the Photo section of the forum.

Thank you.

Ian :D

Great stuff! I really admire your tinkering skills :) And I see you've printed a KNRLR, hehe. Have you used it?

I like your nozzle hack with the steel part, I've never had a plug, but I suppose it could solve the issue many are having.

Your prints look great and I suppose they will look even better with time. I also like the Audi bushings, :D. It would be cool if they were from an Audi R8 so you could have race car parts in your printer, haha.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
