Y Axis Tensioner
Tightening the Y axis pulley is pain since you basically have to pull the entire Y stage off the X axis rods. I suppose this isn’t a bad thing since it forces me to tighten down bolts and oil the various rods.
I designed this Axis Tensioner for the Y Axis last night. Both parts are included in the STL file. I’ve included the Google Sketchup file for anyone who wants to help improve the part. It may be a little disorienting as one of the parts is laid on it’s side to be printable.
- The larger part fits around the edge of the Y axis stage.
- The smaller part fits under the Y axis pulley, around the M6 nut.
- Drop an M3 nut into the slot in the smaller part.
- Insert an M3 x 16 bolt (preferably with a washer) through the slot in the larger part. Rotate to tighten/loosen.
Here’s the Axis Tensioner Y on Thingiverse. Thanks to unrepentantgeek for his Sketchup version of the Cupcake CNC which allowed me to create the screenshot.
Let me know how this works for you.
[...] this is an iterative process. I revised my drawings of the axis tensioner for the Y axis a few times before trying to print it. When I created the screenshot for it I noticed that some [...]
