Thanks for the feedback. I priced out SLS Nylon prints, and the lowest cost is about $20 per part, no supports required. FDM prints were less,...
Added these print cooling ducts to the model: E3D Titan Aero Layer Fan Shroud for 50mm Radial by FDM_Guru I've never had any luck printing a...
40x40 V-Slot ordered on Thursday night, just a tad too early for the Friday free shipping. :( Quoted and ordered 4x HGR15 1500mm rails and 4x HGH...
Since I had to order 4 x 40x40 x 1500mm rails, I figured, eh... why not? I added a Plate Maker kit to the list... So now I can easily make my own...
Long parts, tall parts, long and tall parts... :) I have no specific use case at the moment, though I will probably use it to print out large...
Ball screws are out - too expensive, even with shipping from China.. or perhaps because of shipping from China. I was looking into Hiwin HGR-20...
Appreciate the info, I have heard of melting HDPE into acme nuts. And I've seen others use belts to drive multiple Z screws - but that's not the...
Yeah, ball screws are anti-backlash to begin with, and have low resistance between the screw and the nut.. The ball bearings in the nut actually...
Investigating ballscrews and rails on AliExpress has gotten me quotes ranging from $520 to $840 for 4 sets of rails and 4 sets of ballscrews in...
I naturally couldn't sleep because I was thinking... Some 20mm linear rail and carriage matches up well with 16mm ballscrews 1500mm long. I was...
Could probably use 40x40 uprights. I'd have to figure out an alternative Z axis rail system with the larger gantry plates, or just go with bolt...
Well, a 1500mm height does look interesting. It gives about 1250mm in vertical build volume. [ATTACH]
I'm also looking at 16mm ball screws, 1500mm long. eBay specials priced around $115 each, but that's with ball bearing nuts, machined ends, and...
I'm reconsidering this option now... 12mm lead screws, 3mm lead, single start, 1500mm length. The lead nuts with flanges aren't available as...
An enclosure so big, it looks like a gazebo... Sketched out a shallow pyramid top, to be made out of 1/4" plywood. The side panels are 48"x48",...
It wouldn't be too difficult to generate an OpenScad-based idler pulley/wheel with a 3GT/GT3 profile: Parametric pulley - lots of tooth profiles...
3GT Pulleys, yes. OB has 3GT pulleys listed, 1/4" or 8mm shafts. But not idler wheels..
I'm using smooth idler wheels because OpenBuilds doesn't offer toothed wheels in GT3, unless I want to use aluminum pulleys. I suppose I could...
Dead build, no longer active. See my CoreXY Cube build instead.
You don't quite realize how BIG the build area is going to be, until you get the 26" x 26" aluminum plate... It's HUGE. The surface is protected...
