Inexpensive setup for prototyping

Posted by Monroe Lee King Jr on April 4, 2013 at 2:29pm

 I had some time to search around and find the least expensive way for anyone to get involved with a CNC project of their own! And here's what I came up with!

IMG_20130302_155435.jpg?width=750  5 Axis CNC Break Out Board (BOB) from ebay!

IMG_20130302_155413.jpg?width=750EasyDriver V4.2 also from Ebay!

 Some NEMA 17 stepper motors for $15 each!

IMG_20130302_155345.jpg?width=750  1 X BOB $11.79 http://www.ebay.com/itm/5-Axis-CNC-Breakout-Board-Interface-Adapter-F-Stepper-Motor-Driver-DB25-Cable-/321083753484?pt=LH_DefaultDomain_0&hash=item4ac215440c

  3-5 X EasyDriver $8.99 http://www.ebay.com/itm/EasyDriver-drive-stepper-motor-driver-board-/220922508583?pt=LH_DefaultDomain_0&hash=item337001f527

  3-5 Nema 17 Bi-Polar Stepper Motors $8.30 http://www.ebay.com/itm/CNC-Nema17-for-1-7A-3400g-cm-40mm-length-4-Lead-2-phase-Wantai-Stepper-Motor-/140902530318?pt=LH_DefaultDomain_0&hash=item20ce71fd0e

 So for a basic 3-Axis Machine your looking at about $70 if you already have a PC Power Supply! The steppers I got are 68 oz/in but the one's I listed should be just fine as I cant take full advantage of the 68 oz/in at 12V anyway.

    Does anybody have experience with connecting 3 axis display to this board. Unforunatly for connect dispaly necessary is changing sequence dispaly wiring. I have standard cable but so sequence wiring is ok for TB6560 but not for this board.

     

    Thanks,

    Marcin

    This is great information! Thanks Monroe.  What size of a machine would these parts be suitable for?  Is this what you are using?  Can you recommend any sources for bearings, rods, drive parts, etc.
