Nate I like that idea of the spool, you could even make it screw together, to make it adjustable lengths.:D Like the toridal idea, but most of all I like the EPG spacer idea, it will keep the tube spacing perfect.:cool:
That's looking great Jeff! The stainless hardware really makes it look nice. :) I like the Z axis couplers too. My Hobbed bolt fit nice and snug on my gear.:huh:Oh, just to mention I did this on the hobbed bolt head also, just had to cut the heat shrink off the under side of the bolt head so as not to change the center spacing of the bolt for the filament. You will more than likely be done with the build before I am, still have to put all the electronic's together, also going to try to cast the print bed plates this weekend, I have made the pattern already, still have to make the sand molds, melt the aluminum and pour the molds, it will be an all day project, I'll try to make a video of it as I go through the motions.:) Still trying to post a picture, I have done it before, I'll try a lower pixel, maybe that will help. Ha, success, I lowered the pixels, then the photo's went through, good.:DSounds like a great idea Jeff. I have some at home, I'll give it a try. I remember from somewhere, someone said that silicon spray was the best lube for these things. I'll probably switch to that once I feel the rods are all running smooth and are "broke in". I'm thinking your going to be all caught up to me by the time I get back to work on mine. lolHa Nate, I was installing the Z axis, had an idea for the all thread top nuts above the springs, noticed the plastic was a little larger than the nuts are so I took some heat shrink tubing put it over the nut with the nut screwed on to the all thread, heated it, let it shrink down over the nut and all thread so it would take up the slack as it is inserted into the plastic housing, you can also grease the nut, the shrink tubing around the all thread will keep the dust out, I think this will also help the resolution. Tried to post a picture but couldn't.
Some print ideas Ive been kicking around:
