ecksbot
Derived from
Description
The ecksbot design is a sturdier and sleeker derivative of the Prusa 2 built on EckerTech innovations and putting a little more Sells Mendel back into the mix, making it a true and evolutionary RepRap.
We do not claim this as our own new design but rather another small step in the evolution of the RepRap hobby printer. It is designed around the concepts and efforts of the RepRap core team and should be considered as an extension of the project.
We would like to thank the RepRap core team for inspiring not just us but the entire RepRap community to design, redesign, innovate and think outside the box. Without the core team none of this would be possible.
Keeping with RepRap tradition the ecksbot is released on the GPL license making this a true RepRap 3D printer.

We've just finished assembling the Black PLA Ecksbot I posted in "made" a while back. It goes together quite well in PLA, no real issues. I am glad I added some slots for zip-ties to the X carriage though, they were needed. One annoyance is that the extruder idler/body is a bit big, they touch each other before you have the hobbed bolt tight enough, I nearly have the same issue with the red ABS eckstruder I fitted to my Prusa i2.
I'm currently trying to build one of these and right now I'm stuck on the X carriage using a Nema 17 motor (48 mm length) that seems to be too large for the X carriage since it is right in the path of the belt. I know this is a derivation from the other repraps and it seems to use the same wades extruder, but do you have any specs on what the size of that extruder stepper motor should be? Do you know of any mods to allow for bigger stepper motors on the extruder? If there is nothing out there I will probably attempt to make my own version for it
Yikes! We didn't anticipate anyone using a motor that big for the extruder. The stepper motor we use is a 63 oz-in, 1.5amp, 1.8 degree/step Nema 17 (37mm in length). This motor provides more than enough power to extrude (it's actually a bigger motor than required)
An added benefit to using this more is that it reduces the carriage weight allowing you to print faster.
Hope this helps.
Is this a stylized Prusa? It looks cool, but I don't think it is enogh to change the name of the machine... Its basically a Prusa.
Well then isn’t a Prusa just a cheaped out version of the Sells Mendel? Was that in your view enough to change the name? If you take a closer look you will notice that even though they look similar they are not the same. We started out trying to fix all of design flaws built into the P2 and ended up changing the entire machine. How much of the ecksbot comes from Prusa’s redesign of the Sells Mendel and how much comes directly from the Sells Mendel? This information is available on our blog (http://blog.eckertech.com/?p=1....
This design has been put since last May and there are well over 1,000 ecksbot out there in the world to date. I think that the ecksbot has been accepted as its own design.
I published belt clamps for using GT2 belts on an Ecksbot for the anti-timing belt snobs (read: me) :)
I don't suppose I could ply you for a version of your Y-Carriage which is split into pieces and can be printed on a 140mm square bed?
Maybe small brackets could pin it together?
I might try, but my cad skills are amateure at best right now.
Is it possible to get the .prt solidworks files? I am looking at possibly making one of these and want to make a Bowden extruder mod for one of the Z motor mounts. Would be faster to model off existing part files but I could start from scratch.
Thanks

I really like how you smoothed and curved the parts.
It makes them look more polished and precise.
At the same time, you made no choices that would make them hard to print. Well played sir.
I may have to print my self an ecksbot...
We've created an X-Carriage leveling jig to make it easier to level the ecksbot's x-axis.
Simply place the jig on one of the Y-axis smooth bars with the notched portion of the jig straddling the bar. Next, turn the Z threaded rod closest to the jig to lower the X-axis while swiveling the jig back and forth (by hand) on the smooth bar about half an inch, making sure to not push down on the bar. When the X-axis slightly touches the jig move to the other bar and repeat the process. When both sides are the same height you're x-axis is leveled. You may have to do this a few times to get it just right
This leveling jig could also be used for any reprap x-axis.
When I printed the X-carriage, the screw holes on the bottom fell out after I removed it from the hotbed. It seems half of the screwhole is there, but it doesn't come all the way to the bottom of the piece like in the STL file. Will this be an issue or should I start reprinting this piece?
Reoriented EckerTech_ End_Stop_Holderx3.stl (formally Micro_Switch_Holder.stl), so that it will print on the flat side.
Also, the BarClampx8.stl file has been updated with a bigger smooth rod hole.
The previous hole was a little to tight.
Reoriented the following files, so that they print on the flat side:
BearingHousingInner
BearingHousingOuter
CouplerLeft
CouplerRight
ZBarClamp
What a wonderfully cleaned up kit. Some of the parts are downright sexy!
I've been having a bit of a problem slicing the Y motor mount. I've been using slic3r v0.9.2 and it keeps complaining and lopping off the motor flange. Any ideas?
BTW thanks for a lovely printer set.
Hey, definately a fan of the x-ends, much more printable than some.
Are the bearing idler inner/outer's printed with support? As they are pointing upwards in the air in the stl.
Trying to print the Ecksbot Y Carriage with the Replicator but, it is bigger than the build platform. Can you possibly skrink it down a bit so it will fit within the build area? Thanks..
I selected the option in ReplicatorG to size to 'Fill Build Space!' This scaled the size down by 0.92. I'm sure that might have an effect on hole alignment for the build platform. We'll see when I get all of the hardware in. I'll be donating two builds to my daughter's science and art department.
First, great design. Next, is the STL file for the Eckstruder Block correct? The reason I ask is the file looks different from what you have in the instructions for putting together the Eckstruder. More specifically, the hole where the hobbing bolt goes through is closed on one side. This means the instructions don't match up. Am I missing something with the design?
Nevermind, I fixed my stupid and drilled out the plastic in the holes that were filled. I finished printing all of the parts but, I did have a few issues with the fan cowl not printing the edges around the outside of the fan mounting holes. It seems that the edges are too thin and does not layer correctly..at least not on my Replicator.
Hi Everyone,
Our source files are finally available on github at github.com/eckertech/Ecksbot.
If your have any issues, please let us know.
Thanks!
I think the slot for the M8 nut inside the "X End ..." parts is 1mm to big. I currently try to fix this but I have no luck with my CAD program. Is it possible for you to post a fixed version?
Sorry for the delay in responding. You're right about the 1mm to big. We used the Prusa 2 measurements for this area and didn't realize at the time that it was wrong. Thanks for pointing this out. We appreciate your help here.
We've uploaded new files that fix this problem and have also made source files and updated STL's available on github at github.com/eckertech/Ecksbot.
Thanks again!
Good work. Some of us love working in solidworks, can you provide those source files also. Thanks
Hi Please could you provide a ZIP archive of all the files, this will help us with slow connections. Thanks
I am in the process of making a printer design of my own.
Many of the parts of this design are nice improvements.
And will certainly be inspirational in my design.
I am particularly fond of the eckstruder ( wades extruder mod )
Intresting, but I d`t know about "Y Carriage.STL": table in RepRap - maximum 200x200 mm...


While I have yet to build a printer I find this one most alluring the only thing I dont really care for are the steppers on top rather than bottom mounted.
