• DIY Linear Bearings

    I'm trying to settle on a design, but I was advised to try all 3.  The 3 designs are 1. round linear bearing (current) 2. Y- Linear bearing 3. U Groove wheels.  Im almost ready to print a u groove wheel for a 1/2 emt, and 5x16x5 bearings.  I found 8 x 16 x 5 are also cheap bearings that should be suitable for the Y linear bearing.

    Drilled and bolted the frame.  Cut the sub-board crooked :(. Getting binding and all sorts of twisting.  I could get some movement for the sake of it, but this is definitely making it to a beta version.  Need to spend more time in CAD.  I do have parts for a brushless spindle on the way.

  • Rod holder bushing complete

    Finally got the print settings dialed in for the rod holder.  In the future i'd like to test PLA as a bearing material.  I tried nylon, but it was rather soft.  Igus has some special filament that seems interesting.

    This design was so that I didn't have to "dial in" on a 1mm print nozzle.  I could get the majority of the structure there and print a more precise bushing with a 0.4mm nozzle.  

  • Almost done with first set of printed parts

    Finished a 9 out of the targeted 12 blocks for the minimum needed to move all the axis.  Next step is making rod holders.

    Been working on this project for a couple weeks.  Hope to have something that moves by the end of the month.  See the different version iterations in the gallery.  Original idea was going to be a one piece design.  That evolved into 2 part, a block and a bearing.  Then the bearing wasnt working out great so I got off the shelf bearings.  Check points are: 

    1.  Get 1 axis moving (camera slider)
    2.  Get 2 axis moving (XY Plotter/laser)
    3.  Get 3 axis moving!
