[arcol.hu] Small contribution to delta machines, new hotend variants, pulleys are ready

[Laszlo KREKACS]

Hi,

Just a little headsup to you guys. I'm now working on a delta machine fixation.
That means a 12mm diameter ball of a ball bearing drilled out halfway and
sticked a 40mm stainless steel rod into it which is half threaded (M4).

Tests are pretty promising, I think these will be the most precise
solution available.

I will post some pics tomorrow. Feedbacks and inputs are welcome as always.

The pulleys (T2.5@16, T2.5@32, 608@T2.5, 624@T2.5, 32mm diameter
discs, belts) are also available,
prices are determined, hopefully I will push onto the webshop this
weekend, but if you need immediatly,
just ping me by ordering anything through the webshop or by email.

I have also 605 grooved bearing too.

I'm also working some other things, just for your information.

1. Longer heatsink, if you need longer overall hotend.
2. Bowden style hotend with the necessary bits.
That means pneumatic connection on the hotend top, then pneumatic
tubing, and the mounting plate at the other end of the pneumatic
tubing.
Normal Wade style filament pusher (without any modification) works on
the other end (outside of the machine).
What will be available:
- 2pcs modified pneumatic connector
- pneumatic tubing by meter
- modified heatsink and modified mounting plate
3. Mechanical compatibility with older Rapman machine. Thats an old
duty I still owe some people.

Once the above are rolled out, I'm working again on the next big thing (tm) :)

Inputs and feedbacks are welcome as always.

Best,
Laszlo

Hey, So, just so I understand, you've drilled and tapped..or just drilled, and stuck a 40mm long threaded rod into the ball of a ball joint? Pictures will always say more than words...well generally, But that sounds like a excellent idea. I'll wait for the pictures before I can comment any further. A longer heatsink will be great to have. I had issues with my last filament and heating, a larger cool down area would be good to have.

Hi,

Here is a picture for better understanding:
http://farm8.staticflickr.com/7406/9738431747_05c518aba4_b.jpg

It is only a testing, if we can drill out a regular ball bearing,
and how accurate it is (hence the long bar sticking out).

The final idea is the bar sticking out is half of the length and half threaded.
So it can be either glued or twisted onto something (a carbon rod I suppose).

It's a product idea, but I was required to manufacture 100 of it as a
minimum quantity.
I hope my hunch pays off, in a figurative sense of course:)

The ball will be connected to a magnet with a half circle in it, pic:

Yeah.. the magnetic ball joint is a biggie.  It's a recent development, but looks to be a solid design addition.  It would be nice to be able to change the entire print head assembly with nothing but a cable change out.
