Hello again, remember me?

I have published an instructable about how to make a 3d printer under 200$ - Tower Simple XL.

It's a low cost, full-featured 3D Printer, and the most important thing is, you don't need any 3Dprinted parts to build the 3D Printer. If I have a 3D printer,I don't have to look around how to build a 3D Printer...

If you are interested in creating a 3D Printer, you should have seen it. https://www.instructables.com/id/Building-a-3D-Prin...

And today I brought another more excellent project. Introduce my new machine - Vaster Mini3.

Salute to i3.

## Update v1.2.1 on step 23 ##

2015-09-22

Fan duct .stl file for Mini3 published on thingiverse: http://www.thingiverse.com/thing:1026997

Screws and bolts list added.

Fine-tune.

####

Step 1: Mini3 Version 1.0

This is the original version of Mini3 , I define it as the Version 1.0

I've done a lot of work to upgrade it, the latest Version of Mini3 is 1.2.1 , at 2015-09-22. and I'll show it in the following instructable.

In fact, all the versions are very similar.

What is highlighted in picture 2?

Check this out and find something interesting, http://www.thingiverse.com/thing:5762

Don't waste any materials.

Step 2: Lasercut

Wood thickness 5 mm to 5.2 mm.

Step 3: Assemble the Main Body

Pay attention to the position of the board.

Version1.1 is the same principle.

Step 4: X Axis

Assemble the X axis.

## X-axis part list ##
Synchronizing wheel ; 2GT-20T ; 1

Synchronizing belt ; 2GT belt ; 600mm

Optic axis X- 225mm- Diameter 8mm ; 2

SK08 ; 4

SC8VUU ; 4

SC8UU ; 3

F625 ; 2

Leadscrew nut- T8 ; 2

NEMA17 ; 1

End Stop ; 1

####

Just push-fits SK08/ SCS8VUU/ SCS8UU/ F625/ NEMA17 together.

Step 5: Y Axis

Assemble the Y axis.

## Y-axis part list ##

Synchronizing wheel ; 2GT-20T ; 1

Synchronizing belt ; 2GT belt ; 500mm

Optic axis Y- 245mm- Diameter 8mm ; 2

SK08 ; 4

SC8UU ; 4

F625 ; 2

5mm-8mm Coupling ; 2

NEMA17 ; 3

End Stop ; 1

####

Just push-fits SK08/ SCS8UU/ F625/ NEMA17 and Coupling together.

Step 6: Assemble!

Attach X axis to main body with.

## Z-axis part list ##

Optic axis Z- 318mm- Diameter 8mm ; 2

Leadscrew - T8 -300mm ; 2

End Stop ; 1

####

No zip tie, get stronger.

And now we have successfully assembled a Mini3 V1.0

Mini3 was inspired by my desktop CNC.

I used to think of transforming the CNC to 3D Printer, But its printing speed is too slow. I think if we want to use the CNC to 3D Print, it must use ball bearings instead of leadscrew.

Step 7: Mini3 V1.0

Step 8: Mini3 V1.0

Step 9: Mini3 V1.1 , a New Beginning

After assembled Mini3 V1.0, I found its potential for upgrading and created an upgraded version.

In fact, V1.1 and V1.0 are exactly the same. Except a full version of the shell and some of the details of the adjustment.

Step 10: Mini3 Version 1.1

The latest Version of Mini3 is 1.2.1

2015-09-22

Step 11: Lasercut

Lasercut as usual.

Wood thickness 5 mm to 5.2 mm.

Step 12: Assemble the Main Body

Pay attention to the position of the board.

Step 13: Mini3 V1.1

Step 14: Electronic Parts

In this 3D Printer project, i continuing to use RAMP1.4, So it's the same with Tower Simple XL.

<p>Hi</p><p>That's look great and I want to build it. Can you send to my email all files of this project?</p><p>Email: maitheviet.95@gmail.com</p><p>Thanks</p>
<p>Is it possible to use SCS8UU in place of the SCV8UU? It's harder to source SCV8UU.</p>
<p>Here is mine...</p><p>added</p><ul><br><li>LED light<li>spool holder<li>filament guide</ul><p>works fine</p><p>requires fine adjustement of the plate but really efficient for a so &quot;cheap&quot; printer.</p><p>works fine !</p>
<p>Hey, I was wondering if you could please help me.</p><p>Did you use Cura and the hex file provided? and if so how did you get it to work?</p><p>I have built one of these, its fully assembled but I can't connect the printer to Cura and there doesn't seem to be the option to manually select a com port in the new version like how you can in Pronterface. But I'm not sure if that is the problem. Since Cura isn't working for me, I uploaded the hex file using xloader and LCD is lighting up fine with the text etc but its still useless as I can't connect to the program in order to print. I also tried Pronterface and used sprinter. The printer connected fine and I can manually move the motors with the x,y,z commands but the end stops etc don't work and when I press homing buttons, all the x,y,z axis try to keep moving and won't stop unless I pull the plug. I assumed the values in the firmware are wrong somewhere because it was not written specifically for this printer but I don't know what the correct values or settings would be for this printer to work. </p><p>I don't know what to do since this is my first attempt at trying to do anything like this. Any help would be much appreciated.</p>
Hi, I first used the hex file provided with the instructable. If you want to, you can. I did it for the firsts prints but I moved to Marlin Firmware. If you want to print, you have to put your gcode on a SDcard. For me it is safier but if you want to manage your mprinter, you should try Repetier. You can tune the firmware , set a lot of thing including communication issues ( Baud, COM port...) The endstop issue may come from the logic used of your contact ( NO or NC). If you can move one axis in one direction only, not in the reverse one, try to move with endstop pressed. If ok, go in the configuration.h file to reverse the logic of the enstops. This printer is niced but in my opinion requires some minors adjustement in the design. Building a bigger one with two extruders &amp; heated bed. tell me !
<p>Hi</p><p>That's look great and I want to build it. Can you send to my email all files of this project?</p><p>Email: mohsennoruzi@gmail.com</p><p>Thanks</p>
<p>what currceny kind is it?</p><p>is it USD?</p>
<p>What ardiuno program did you use? I am building a two extruder printer and would like so help.</p>
Here is what I have so far.
What size of nema17 motors did you use 36-78oz? Great build so far.
<p>Hello ,</p><p>What is the size of the print area ?</p>
<p>These instructions are awesome and the design is beautiful. I can't wait to build it!</p>
where is the firmware?
<p>Hi Almus, I have built your first printer, the tower simple, and I'm wondering what are the improvements from that to this one, .<br></p><p>Also I would like to know if there are any parts to the Mini3 that I can print with the tower to reduce costs.<br><br>Thanks.</p>
<p>Hi buddy. the tower simple and the mini3 is completely different in structure, Mini3 is stronger and stable, it's done with the aim of obtaining a more accurate finish.</p>
Ni Almus, Can you upload the firmware?
<p>Is the firmware for RAMPS 1.4 the same as used for the tower simple?</p>
<p>That's what I imagined, I'll try to make this one also then, since I have a lot of leftovers from building the tower. </p><p>Thanks man for those projects it has been a lot of fun working on them.</p>
<p>Hi I made one frame. I'm looking but I made it longer. It's a Vaster MINI3 XL :-)</p><p>Build area 300x200 mm</p><p>Thanks</p>
<p>Hello, can somebody share a link to rerap I can not find it. I will build one for me.</p><p>GREAT PROJECT</p>
Hello. How am I going to do or where I'm going to download the software? Do you know less about the software that helps.<br>
<p>Thanks for this excellent tutorial. </p><p>But what custom firware use for the 1.4 RAMPS and/or the all-in-one MKS board ?</p><p>Thank you.</p>
And, can you upload the files of the laser cut with the screen display because that files doesent are online
<p>I have a modified file in .ai for lasercutting. But expanded some square holes for fitting 6mm mdf. In the netherlands, it seems to be hard to get 5mm wood.<br>Also, download a free autocad designer, follow some tutorials and you are able to get en better LCD display en make it in Autocad. I have modified the file to fit a lcd type 12864</p>
But the sd slot where you put?
<p>I have not built it yet and even printed all the sides. Due the fact that everyone who has a laser cutter asks a too much just for lasercutting. Regular price is 60euros for a few pieces of wood. So still looking for a free service.</p><p>As far as i can see, the SD card will be at the back of the display. Look at some other projects here, you might want to add a raspberry for external storage and wifi.</p>
Yeah, I look one tutoriol of how to add wi-fi to the printer with octaprint
Where does the F625 go? I dont see it's place
<p>Cannot find v1.2.1 files on reprap.org</p>
Wath kind of motherboar did you use
<p>What kind of wood are recommended for the frame of Mini3 V1.2? Also the dwg folder for the frame of V1.2.1 pls. (or told me how can I amend the dwg file of Mini3 V1.2 to V1.2.1)</p>
Anyone knows in what directions it moves? If it's up-down left-right and the table if it move front-back?
Building dimensions :<br>12x15x12 cm <br>&quot;almost 5*6*5 inch&quot;
<p>Great project! Voted.</p>
<p>I voted for you!</p>
What are the biggest dimensions which the printer works?
Are you from Germany? I also want to know the Building Dimensions
<p>I have been looking recently into creating one of these and this one looks pretty interesting. Any chance you could update with links to the parts? Will look forward to the example models.</p><p>Gave you my vote so good luck in the contest. :)</p>
If we can convert the DWG files to SVG, I can upload them to Ponoko and get them cut.
<p>How much it cost by Ponoko?</p>
<p>We would need to convert the DXF files to SVG and upload to see what it will cost. Whatever it is, it will be fairly reasonable. I might take the DXF to my MakerSpace and cut it on the laser there.</p>
Thank you for your vote. <br>I'm busy printing some models for my friends. They are doing an interesting project and my 3Dprinter have to work for them.
<p>This is awesome! I voted for you as well! Keep up the good work!</p>
<p>Thank you buddy, i will continue to improve this project, just creat a fan duct, keep moving on.</p>
<p>Would you happen to have the .stl file for the fan duct pictured? I have a Reprap Prusa i3 and my fan duct keeps messing up my prints because it is too large.</p>
<p>Fan duct .stl file for Mini3 published on <a href="http://www.thingiverse.com/thing:1026997" rel="nofollow" style="">http://www.thingiverse.com/thing:1026997</a></p><p>check it out ;)</p>
<p>Hello,</p><p>Thank you! I have followed you on thingiverse. What is the difference between the Fan-L and Fan-R ?</p><div><p>Eric</p></div>
hi<br><br>this is a great project ...however simple towerx has more details in description and the part lists! Can you please add the screws and bolts quantities<br><br>Regards <br>Andreas
<p>Now we have it , the list of screws and bolts ;)</p>
<p>Hello andreas, thank you for your feedback, i will add the number of screws and bolts.</p>
