reprapdiscount ordbot hadron, build and kit review

I already have an ATI ordbot hadron, when sourcing the parts for this printer may / june of last year I had discussion with the people at RepRapdiscount an ebay seller of electronics from Hong Kong. They too agreed it was a nice platform and unknown to me started the process of sourcing the pieces to supply their own kits. Later in the year they let me know what they were doing and had me test various components on my own printer for form and function. All of those pieces, V-Wheels, Pulleys, Belts, are still running reliably with no issue.

Towards the end of the year they got very busy and I headed off for a long holiday, and by the time this year started things had remained busy for RRD as they had some new electronics packages on the move.

Today I recieved in the mail a large box from reprapdiscount, they have started selling these to resellers and through ebay.



Inside one semi complete ordbot hadron build platform, + electronics kit




20 minutes later a 3d printer platform is built a further 10 minutes of adjustment and its squared and ready for electronics, extruder, heated bed.



Have the required power supply, a hotend from scwerta, an extruder already printed but have to decide where I will be mounting the electronics, whether i want the pain of the hidden wiring and a few ancillary bits to source.

The kit itself went together with very little effort, RRD have done 95% of the assembly, my previous kit was bags and bags of small components and bolts and nuts, this one is much simpler and quicker. Adjustment at this point is pretty rudimentary, and there are a couple of upgraded parts on my ATI hadron that i will be printing for the rrd hadron. All in all it is well built, well packaged, amd shipped fast from Hong Kong.

Thought I'd better add something for the purposes of transparency. Yes RRD sent me this kit for free, they are expecting me to assess the kit and make suggestions for changes. I do not sell goods on behalf of RRD, I am not financially associated with RRD. If the kit is good I will praise it, if it is bad I will endeavour to let you and RRD know how it should be improved.

first improvement that should be on all ordbots and rolled back into the design is a set of these

[www.thingiverse.com]

The nutblocks on the Z threaded rods are overconstrained against the makerslide, this leads to binding if not well adjusted and Z wobble apparent in the vertical walls of printed objects. These parts give the nutblock a little frredom in the X and Y direction to move without imparting this movement onthe frame. They also prevent the crash into the bed scenario.

I have been using this design on my ATI sourced Ordbot for 2 months now and the difference is remarkable.

Here is the new piece mounted


Still have some decisions to make re wiring and placement of electronics. Seriously contemplating putting all electronics in a standalone box that sits beside the printer, this will free up the back of the handle plate for a possible future multi bowden extruder setup.

Dont need to do this quickly so will keep assessing choices.

I was wondering how long it would be until the Chinese got into the game as a frame source.
Maybe they already had but I was not aware of it?

It's only a matter of time until builders will be flooded with other Chinese offerings and the prices should come down.
It has happened in many other markets and 3D printing will be getting their attention
I have already seen what happened in the LED bike light market
They came in with very inexpensive LED lights and that made it difficult for small builders to compete

Oh well, that's life today

Anywho, the design looks nice from where I sit

If possible take all your images with good light and make sure they are in focus
It's hard to tell what the assembled machine looks like in the image above

Thanks and keep us up to date

My projects are listed here - [www.el34world.com]

I built an ATI mechanicals Ordbot Hadron last August and have been using it ever since.
RAMPS, Marlin, Repitier-host, win XP64
Great little printer.
Lots of problems and tweeks to get decent prints.
Z-Axis problems and extruder most frustrating.
My extruder a mBot Mk7 1.75 mm
I have used PLA, ABS, Nylon.

Mods -- Z-axis couplers, Z-axis stabilizers . cooling, glass bed

Important level bed, consistant extrusion, correct settings for all parameters, getting plastic to stick to bed

Rumba
Where can I see more info on extruders
is there a website / store?

I noticed some kits from Reprapdiscount on ebay, I have always liked the look of the Ord bots.

I'd like to know if the Hadron can fit a dual or triple extruder? Or maybe the X can be extended to allow for this without losing build area?

I have 1m of makerslide rail spare, maybe I can use that here.

Hi,

I'm new in the forum just bought an Ordbor hadron in DIY kit 2 month ago from reprapdiscount, very fast delivery and good support (fast answear to my emailssss).

To BOBC, the number of extruder sepend of the electronic and software i don't think that you can easely put 3 head and most of the soft are able to manage on or two extruder.

I did a presentation here (in french sorry)

Here are some pictures of my OrdBot :

Before wiring



Adding some light

First day printing (one of the first printing - PLA)

See you

Hi Jean-Luc

The electronics and software is not a problem for me, I have a triple extruder electronics. The problem is I am not so good on the mechanical side, and there is currently only one RepRap with a triple extruder.

There is plenty of space on hadron extruder carriage to fit double extruder, maybe also a triple extruder depends how big is the triple extruder.

I have just built an Ord Bot Hadron which I got from ATI. Had it shipped from the US to the UK. I am a newbie (or was) and I spent about 50 hours putting it together. This included the mechanical build and wiring the electronics. There was no pre assembly at all, just a box of bits without any instructions. I damaged the Arduino and Ramps boards by wrongly connecting the end stops. I had to replace them.
On the plus side it is built using Makerslide and this makes it a really nice compact and robust design. Better than steel rods and plastic corners.
The extruder was not included and I made the mistake of buying a QU-BD MBE extruder. I wasted many many hours trying to get it working and finally gave up. I have now got a bog standard Gregs Wade extruder with a hotends.com jhead. I haven't looked back since.
Still a few problems but getting there slowly.
Twin extruders are possible but it would be better with a bowden setup imho. Two motors flying about at high speed would be too much weight I think. This is a project I plan in the future. One advantage is the Ord Bot can print fast.
Maybe I should have ordered mine from Reprapdiscount. Looks a nice job.

i think double extruder for 1.75mm filament it's still okay since the weight it's around 550g

Whole big Ordbot forum on Buildlog site!

Hi Elvira,

I think are you talking about two direct drive extruders which are a bit lighter. Two Wade extruders would be heavier.

Running at 200% feed rate with two Wade/ Nema 17 motors would shake the Ord Bot about I think.

The problem with a Bowden setup is where to mount the extruders? Maybe move the electonics to a separate box to make space.

I am with you on the bowden setup, the only thing for me is I have never used them before. Initially I would be willing to trace some speed for multiple nozzles. When I have electronics and firmware working with 3, I was thinking of going to bowden setup and see just how many hotends I can fit on one carriage I hope to have hardware support for 9 extruders.

I *think* a piece of t-slot would bolt across the top of the ordbot, which could be used to mount extruders.

I find t-slot much nicer than threaded rod, it may be not be so universal as threaded rod, but is much more solid, and dare I say "professional quality". There's a supplier in the UK which provide a great service who also cut to size.

I have to make a demo showing the Bulldog Extruder acting as bowden, i will try to find some place on ordbot , i am just too busy

bobc:

a section of t-slot across the top maybe the way to go. I have an account with Mitsumi who can supply the necessary parts.
Just leaves the question of relocating the controller electronics. Keeping it built into the printer would be my preference rather than having it in housed in a seperate box with plugs.

Hi BoBc.

I understand your problem.
They are always solution.
First, are you using a OrdBot hadron ? If yes i think That it´s not à big problem to have 2 extruders face to face.
For 3 extruders i would place them in star or triangle with an extention plate.
If you are worried about the extruder mouve, you can put the extruder on the back of the printer (like ultimaker extruder system or Bowden extruder) in this case i think that you could be able to have 4 extruders, 4 heads together in the mouving plate (X) and the extruders in the back.

But i will have an other question, why will you need to use more than 2 extruders? Or what for?

See you

JL

PS : they are some dual extruder like this one [www.thingiverse.com]
Dual flying motors extruder. Two could maybe feet in a extended carriage (x mouving plate)

I'm convinced by the Hadron frame, so I have ordered one.

Multiple colours, materials.

Hi,

I saw this triple extruder : http://richrap.com/?p=121

I was planning to put a piece of fram on the top.
I have ordered it.
It will be more rigid and it will handel the pla or abs.
I will post pictures.

I've now built most of a Hadron, just need to do final assembly. It feels like a solid piece of kit!

Extending the axes looks as easy as I hoped, but I want to get printing with the standard build and a single extruder first.
