I'm a bit late to this, but this project is uploaded! It's already v5. There were plenty of lessons and changes and fried chips to get to here, but that's a lot to write out. I (for once) documented a bunch of it in a long google doc: https://docs.google.com/document/d/10RtGc0HOGberA7v5jZShsxAbZBDxf0yVxyILOeaE-VQ/edit?usp=sharingThe...
Well, I sprinted through the week and got the shredder working! Found the master link I needed to close the chain.split the chain to the length I needed, and hooked it up to the sprockets.I'm very pleased that it fits nicely over a bucket. I don't have...
OverviewA 3D printed strain wave gear, using a HTD 300-5M-20 and 608 bearings. The belt has 60 teeth, for 30 revolutions of stepper the outer gear rotates once, resulting in a -30:1 gear ratio. Bill of materials Material Quantity Dimensions HTD belt...
Typical Cycloidal Transmissions consist of four main sections. Input shaft and eccentric bearingCycloidal Gear(s)ring pins and housingOutput rollers and shaft The way that the sections are arranged are with the input shaft on one side and the output...
Turret Prototype one is done! This prototype is mostly to explore the mechanics of the eventual design, as the design needed for this project will have to be very different than the vast majority posted online. So I decided to start off this project...
I managed to increase my machine's bed size from 35x35x35mm to 40x40x40mm. It may seem small but the 10mm increase in dimension is huge for me. Every millimeter helps! It all started when I learned that there are stepper motor sliders similar to the...
After stumbling onto this article by Niko Plath I started to look into speeds and feeds again. Every time I look into this I get confused. There is a lot of talk about it, but the numbers never seem to have much meaning. ...
First log! For context, here's v1 and v2 (sorry about table formatting, couldn't figure out side-by-side images):v1:V2, with housing and drive gear:V2, just the spinny bits: I just printed out all of the parts, and it's not going to work. ...
Everything arrived, including the 8' long tube stuffed with bubble wrap and CFRP square tubing. Exciting! Two CAD model changes to make prior to getting out the carbide-tipped jigsaw and Space Glue:1) I'm going to increase the width of the pitch ring...
So I started by experimenting plenty of solution for detection of the note. First thing first, I tested springs, it worked but had many constraints (especially weight handling and durability). I then looked at pressure detection, but again, I had...
I guess I'm going to seem pretty fickle about the software environment, but it's really born of ignorance rather than wishy-washy-ness.Earlier, I commented that I would probably use Lua so that I could take advantage of multi-threading to simplify the...
Step 2: Motion. This post is actually a long time coming, as I did some of this assembly a year ago. I have added gears, steppers, end switches, and RAMPS board. LM8UU linear bearings are from vxb.com. I had the top bearings on-hand. They are standard...
Well, it's time for the first bad report... :-(Received the production samples. Excellent build. In fact so much excellent that it has created a problem on it own.In the earlier prototypes I used to work with a different PCB factory which had more limited...
Note 1: I capitalize "X-axis", "Z-height" and the like for legibility when scanning/skimming; pedants can hate me later.Note 2: This is where idealistic, that is mimal change for best outcome, modifications are. For measurements and construction details...
Well, I spent an entire day designing a pseudo bevel gear - and it works. Quite a boring update, but the implications of what I can do with it are quite great. I've been toying with the idea for a while but...
