You need camtasia or something to grab screens better, wondering if the induction mount should be in-line with nozzle or Z screw, I cant tell from your vid but it doesnt look like its in-line, maybe marlin can have offsets in 2 directions? maybe it doesnt matter?

Dual E3d mount for Prusa I3

I don't Actually own the Prusa any More I sold it on about 3-4 months Ago I am now using a large Delta with 350mm diameter bed.

But I have a quad extruder printer under construction which will use a E3D Kraken water cooled hotend

Doug

So by modelling I see there is a problem before I can even think about printing.
Two things to remember are that the X axis mount and the extruder head mount are both printed by Replikeo.

The Bowden mount holes do not line up with the X axis mount holes. I am getting other mounts to see who is at fault here.

I imported another Bowden holder and found the holes of the Replikeo are misaligned again.
So now I have to actually measure the spacing on my printer to see if the STL file is incorrect or Replikeo has its own.
If Replikeo has its own then there are grounds for a modification to become aligned with the standard.
If the Replikeo x rail mount is off also then I will have to print a Bowden mount to match to print another to get to the standards or I simply print a standard Bowden mount with a new X axis rail mount. Argh.
But better to find out now than after material expenditure.

So I import the Replikeo x axis carriage stl and find the hole spacing matches the Replikeo dual hotend mount. This stands to reason.

This points out that the Replikeo are their own standard. I now have to physically measure the parts to be absolutely sure that the files are incorrect or the parts are not standard.

I have a very rare situation here. There is a Microcenter a mile away with which I can just run down there and do a part check. The techs love it when I come in there with 3d internals.

The red block is the standard distance of the bolt holes of a Prusa i3 x axis outside edge to outside edge.
The yellow part is the Replikeo x axis stl.
The green is the Replikeo dual hot end holder stl.
As can be seen the standard spacing is 1.2 mm greater than the Replikeo spacing.

So this exercise commands two things.
1: Replikeo has a wide array of compliance problems.
2. I have to print an X axis rail mount along with my designed Bowden holder to conform to the Prusa standard.
In regards to the X axis I now have to verify the linear bearing spacing to see if the dual X axis rails conform to the Prusa standard distance apart.

I now have a course of action to request and receive something that will work. I have to munge some stls together that I have into a printable submission.
Off I go.

After much deliberating I pulled two STLs together and sent out for printing at a shop just up in Morrison, Colo. I should be able to pickup on Wednesday.

Tada! Part made by munging two stls together in Tinkercad then shipping off to RA3d Technologies, Morrison, Co. www.Ra3dTech.com
A great part!

Giantkiller - I am in a very similar situation. I purchased a Replikeo dual extruder. Finished the build with my kids, played with the software, and had big problems with printing.

I dislike the dual extruder mount a lot. It may have been my fault, it may be the problems I am having with the extruding, but the mount is sagging due to the heat from the extruder.

I am thinking of upgrading the mount. Would you share the stl files for the design you had made? Would you mind if I asked that company to print a set and send them to me?

Thanks.

Open up a tinkercad account and look for BowdenPrusaHeadBase and BowdenPrusaHeadMountCap.
Let me know if this doesnt work. I would rather pass around clicks than files. I hope this works for you.

I know your pain. I have switched out the extruders to a single Omerod mount Bowden Herringbone with E3d V6 hotend for now.
Then I will work the dual aspect of it and progress to there. The leveling of both Relikeo print heads is not the way to go. So I want to design in a better mechanism.

Some suggestions...

I have printed many parts that screw together and have developed a few techniques that make things work better.

1) you have the two pieces butted against each other and are relying on the screws to align them. I have been designing parts so that there are collars around the screw holes in one part and mating depressions in the opposite parts so that the parts align themselves when put together:







2) Use screws that are designed to go into plastic (thread rolling screws)

3) For parts that get assembled and disassembled a lot, threaded inserts are a good idea.

4) Using modifiers in slic3r to change the infill density around a screw hole to 100%. This gives the screws something solid to bite into.

@DD,
This was cool. I suspect that the SLICR mods would have to be outside Pronterface.
I haven't seen where I can get under the hood in there. SLICR is adapted into Pronterface.

@Verrin13,
Here are the Prusa e3d v6 mount stls.
