First of all I would like to thank Skarab for the project and design, I chose this model as my first 3D Printer.

As I live in Brazil, in the interior of the State of São Paulo, here there are very few providers of laser cutting services or cnc router, the cost in other nearby cities is too high, and this financial and logistic impediment arises in my path.

I am a good carpenter and I thought of building the horizontal and vertical platforms manually, yes I know it will be difficult but it is my viable alternative and I have a certain talent with symmetry.

In SCAD, the dimensions in the files are only fixed on the external parts of the Axis of the software. I need these dimensions throughout the piece and the cuts with details, but I can not extract this information in detail.

Through SCAD I have exported in SVG format, but the dimension data do not accompany the export vector.

I wonder if there is a PDF or PNG format file, even in SVG, with the MM data of the holes and notches, and the lowering of the wood at the pulley and motor points and axes of the horizontal Y-axis plate.

How high is the pulley recess? 7.5mm? Half the total thickness of the 15mm mdf? What about the Y axes? Engine Fitting?

Although very efficient computerized cutting, it would be nice to have this plan of cutting and drilling without using a CNC, and in PDF format, I know that sounds good beginner, but I felt very lack of these dimensions to do in the style do you even if a CNC .

Thank you to anyone willing to read and who knows how to guide me with a light!

Again thanks Skarab and the whole RepRap community !!

So I want the speed and quietness of v-slot and wheels, and the low price point of MDF. I think I will set out to build iTopie with 2020 v-slot instead of round shafts and linear bearings.

I've build an itpoie machine from scratch many thanks to author/s great documentation page everything fits well and sharp, its easy to build even for first printer like me =D

But I think I've a problem in X axis my carriage have a lot of vibration make a lot of awful noise and the vibration are filled in the nozzle. I'm using drive A4988 in ramps I've tune the drive.

Is anyone else who has had this problem? What we can done to solve or minimize this?

I have written 3 blogs on the following themes:
1. Why iTopie?
2. Building the frame
3. Final assembly of the printer

I have tried not to repeat too much of what is there on the already very good build wiki. I have mainly highlighted where I differ from the build and what parts/tools I used.

I just went n picked up the frame, all parts are there, no missing foot. Also, I had an extra frame cut to help those who want to make an itopie and don't have access to a CNC. So, anyone in India, just ping me and I can deliver you the frame.

Will reach out with more updates on the build.]]> kaustubh General Mendel Topics Sat, 09 Jul 2016 08:03:16 -0400 https://reprap.org/forum/read.php?151,443928,685312#msg-685312 Re: RepRap iTopie - A Prusa i3 evolution - Development discussion https://reprap.org/forum/read.php?151,443928,685312#msg-685312 Super, I expect to see more.

By the way I see one foot is missing on the photo from the CNC shop.

I have just started my build of iTopie in India. I have started a blog to document this : [n00bmaker.blogspot.in]. I would love to hear from you guys.

This will be my 3rd reprap, 1) Prusa Rework (bought as a kit) 2) Cyclone PCB Factory and now 3) iTopie. Considering I bought my first 3d printer in 4 months ago, I think I have gotten addicted to this very time consuming activity (:D.

But anyways, wish me luck and thank you skarab for the brilliant design.]]> kaustubh General Mendel Topics Sat, 09 Jul 2016 05:33:11 -0400 https://reprap.org/forum/read.php?151,443928,666672#msg-666672 Re: RepRap iTopie - A Prusa i3 evolution - Development discussion https://reprap.org/forum/read.php?151,443928,666672#msg-666672 evetanlm General Mendel Topics Sun, 22 May 2016 22:32:45 -0400 https://reprap.org/forum/read.php?151,443928,666515#msg-666515 Re: RepRap iTopie - A Prusa i3 evolution - Development discussion https://reprap.org/forum/read.php?151,443928,666515#msg-666515
As for the screws in the right XZ holder to avoid Z rod warping, why did you decided to not have them in the final setup?

@barrasman Unfortunately I do not have time to produce more documentation and even less to make several versions of the machine code files.

@all But it is an open-source project and any help is appreciated, feel free to participate and complete the wiki.

@evetanlm, @FherraZ The shop must produce machine code file (GCode) from the DXF files. All he needs to know is that the pockets are 6mm.

I want to thank skarab for a great design, I am really new to CNC parts and I had a hard time making a modification to make the frame taller because I already have 50cm smooth rods, so I made the vertical frame 10cm taller.

Also I have added the ABC top plates made by Chaser30 and I would really like if someone take a look at the uploaded files.

I just have some doubts on what to do with the DXF/DWF? I just hand it over to the shop?]]> FherraZ General Mendel Topics Tue, 17 May 2016 18:48:35 -0400 https://reprap.org/forum/read.php?151,443928,662899#msg-662899 Re: RepRap iTopie - A Prusa i3 evolution - Development discussion https://reprap.org/forum/read.php?151,443928,662899#msg-662899
I'm now building my iTopie-C (C stand for chamber, since it will have a closed chamber). For that I have increased the horizontal plate, but I still have to figure out the chamber itself. For now I went to the Lisbon FabLab and had the frame done in the CNC router:



The DXF file can be downloaded from here: [www.dropbox.com]

And here is my B.O.M.: [docs.google.com]

The RepRap wiki and manuals are great, but they seem incomplete, specially in the final part - do you intend on adding more information?

Just a quick question: I've noticed that in your first build, you had this screws in the right XZ holder to avoid Z rod warping, right?



but in the final release, this screws are not there - why did you drop them?



I'm still waiting for almost all of the components (coming in the "slow boat from China"), so I'll be assembling the frame with no rush. ;) I'll kep you all updated :D

CNC machining leaves round inside corners due to the diameter of the tool. These 45 degree cuts inside the corners take care of that limitation.

That feature is usually taken care of by the CAM software that creates the machining code out of the DXF file, so it is not part of the design.]]> misan General Mendel Topics Sat, 09 Apr 2016 18:38:40 -0400 https://reprap.org/forum/read.php?151,443928,650427#msg-650427 Re: RepRap iTopie - A Prusa i3 evolution - Development discussion https://reprap.org/forum/read.php?151,443928,650427#msg-650427
As for the holes I was talking about are the ones you see in the inside corners marked in red:



But I also noted that in some other inside corners there are no holes (green circle). With the corner holes, one needs to fill the resulting gap with something (I was thinking glue with sawdust)... without the holes, those corners need to be made square with a file, right?

I'll share my drawings and photos of the resulting frame ;)

Hi Skarab, I saw your iTopie the first time in Thomas Sanladerer video, and I just knew this had to be my choice for my 1st 3D printer.
Good choice for a first printer ;)

But I plan on expanding the horizontal plate, so that I can install some kind of greenhouse to keep the temperature more stable, and also to be able to print ABS with a proper exhaust system. It will have a slightly larger footprint, but not by much.

Any thoughts on this?

I'm not also sold on having the electronics under the printer - yeah it gives a clean look, but way out of reach for tinkering and maintenance. Still haven't figured it out where I will be putting them, since I also don't want them inside the greenhouse (heat and electronics don't mix well) - maybe increase even more the horizontal plate?
It is a RepRap, she is made to be modified / improved. Try, share and see what happens.

I also saw in the video, that some holes had the corners drilled, but in the DXF files there is nothing like that...
I do not understand what you're talking about. (Maybe a picture?)

As for the rest of the setup, I'll probably go with a more common Mega + RAMPs, etc. Extruder I was thinking about the E3D V.6, as it gets so much praise, even comparing it with the Hexagon.
