This design has been made by one of my friend and I have built one exactly like his. So we currently have 2 machines like this one.
This is my first instructable so maybe there will be a couple of things missing, please feel free to ask or post comments.
If you are planning to make one like that, please send me picture of the final results so I can add it to this page.
**This machine is a derivative of the machine you can find on**
*** NEW FILES JUST ARRIVED ***
I've done all the drawing with METRIC measurement and more precise parts identification. I Had some request for metric measurements.
I will probably upgrade the imperial one soon, so you're gonna have the exact same drawings and with more accurate information.
I have postes new pics on step 9 =)
Step 1: Having the Plans
Step 2: Cutting MDF
After that, print the CAD of all the parts and cut/drill them.
The Drawing.Rar contains all the MDF main parts.
16 Dec 2011 - New Drawings !!! I had some times this morning and it took me 3 hours to redraw every parts with IMP and METRIC measurements, hope you will enjoy it.
Merry Christmas to all of you
Step 3: Getting Hardware
I took mine from
www.leevalley.com , i guess you can get them from almost all woodworking shop on the net.
The aluminium angles are 3/4 X 1/8 angles from RONA or any suppliers near your home. You'll need
2X 36" for the X axe
2X 22" for the Y axe
and 2 11" angle for the Z axe
And ONE aluminium angle 1"X1" x 1/8 for the linear bearings.
You'll need 30 bearings Bearing Size: 8mm x 22mm x 7mm
( I took skateboard bearings from ebay )
The lead screws are the length of : 36" , 24" , 9"
I took them from http://myworld.ebay.com/precisiontechmachining/
Step 4: Mechanism
Here I will post picture and drawing of the mechanism. For the moment i only posted a render of the back of the machine ( the Y axis ), it's easy to figure out all the other axis ( it's exactly the same principle )
Step 5: Assembling
Step 6: The Electronic Part
I added 2 fans because the drive become REALLY hot so if you don't want to kill it, cool it !
Step 7: Adding the T-Slot
I got each t-slot for 11$ ea.
After that, you just have to put a 1/4" hex bolt upside down and make some support for your pieces. I'll add more pics later
Step 8: Total Cost
Bearings : about 30$
Lead Screw and antibacklash nut : 135$
Power supply : 50
Steppers : 49$ each ( 150$ )
Gecko drive : roughly 250$
Bolt and cross dowel : 50$
Aluminium angles : 55$
Rough total : 755$
Step 9: UPGRADE
Special thanks to my friend Max for the idea.
