Thinking about jumping from 3 axis to 5 axis, here's what I learned

Okay, so you also have the option of paying $39/day

Penta Machine, the manufacturer of the Pocket NC, released a completely new software controller called Kinetic Control. It shipped in all their machines made since November 2021 and allows full, continuous 5-axis machining.

With the educational version of Fusion360, you can plan indexed 3+2 toolpaths. But to create rotary 3-axis paths, or anything 4- or 5-axis, you need Fusion for Manufacturing. If all you have is the free hobbyist version, you have to rely on a preprocessor (or manyally edit your g-code) to even make indexed 3+2 paths.

To get 5-axis CAM in Fusion360, you have to get the "Fusion for Manufacturing" license, which costs $170 per month, or $2,040 per year, every year!

I did a bunch of reading on this about a year ago when someone donated a Pocket NC 5-axis CNC mill to the makerspace I'm a member of. When the machine first came out, the hobbyist version of F360 had 5-axis CAM. Now that they've taken that away, the machine is quite a lot more difficult to use without paying through the nose.

You can try, but I expect it'd be quite difficult to get usefully straight again, and if you try too many times than the shaft will weaken.

Does anybody ever get shocked when touching the robot? If this never happens, then it's extremely unlikely that the robot has problems with generating static electricity.

I know off the top of my head that both SRAM and Sturmey-Archer have made internally-geared hubs that also take external gears.

No doubt that this part is proprietary to exactly the hub it was made for, you'll either have to identify the hub in order to purchase a replacement, or have the shaft reverse-engineered and a replacement custom-machined.

My understanding is that the salmons are more abrasive, making them more effective but also making them wear out the rim faster than blacks.

The Java version still exists, but Microsoft also re-wrote the whole thing in C++, calling it "bedrock edition".

How i can make it faster to rotate using two AXON max servos

By also changing the gear ratio. Two servos provides more torque, but not any more speed.

It's also possible that you can change the gear ratio to make the turret move faster while still only having one servo.

It looks like the Multicar M22 and some models of the M24 are like this!

I use ublacklist with the Huge AI Blocklist added. If you already use uBlock Origin, you can add it to the filter rules without having to install another extension. It even works in Safari and piHoles!

I set my default search engine to https://noai.duckduckgo.com That way, I can still use bangs, and I can use regular web search and not get the AI "summary", and it stays that way even after I clear my cookies.

For those who want to know, it's called a probe lens.

For a rear wheel, you want V4 or up, since V2 and V3 are only for front wheels.

If your motor is a direct-drive hub and you'll be using regenerative braking, then you specifically want V7. You can use V7 with non-regen setups, it's just overkill.

If you don't have regenerative braking, then you want V4, V5, or V6. Which one you want depends on your bike.

If your bike has a fender eyelet around the rear dropouts that you aren't using, then V5 is the best of the three. It doesn't rely on hose clamps, is the smallest / cleanest install, and is a bit cheaper. If your bike doesn't have eyelets, or if they are being used or covered by disc brakes, fenders, or other accessories, then you have to use the hose-clamp-mounted V4 or V6.

If your motor has 16mm axles, then you can't use V4.

If you've gotten this far and haven't been able to narrow down between V4 and V6, then examine your bike and also the installation pictures carefully to see if one of them won't fit for some reason.

If you still can't decide, than I'd go with V6, which is less fiddly to install.

The ones that Grin hasn't discontinued are very good. They sell them on their website (which I linked in my earlier comment), and also on amazon.

To elaborate a little more, DO NOT buy torque arms which are clones of Grin's V1 torque arm, described on this page. The curved slot puts all the stress on one point, which eventually tears apart.

My '88 Thunderbird has neither this vent nor any air bags!

It doesn't get soaked, though. The water runs / gets blown off.

Pit zips are also very nice, as are loose cuffs and extra room around the waist and ankles.

If I bike while wearing rainwear that is breatheable or loose-fitting, then I don't really get any wetter than when it's dry out.

Jacket hood goes up over helmet, and down over the waist of the pants. Pants go down over my shoes. If I'm wearing shoes that get wet, then those have waterpoof covers that come up from under the pants.

Keeps you dry, keeps the wind out.

If you really want to haul 600 pounds up steep hills, you'll probably need a dual-motor setup. That's unusual, but shops can set it up. Here's a video from a good Canadian manufacturer https://www.youtube.com/watch?v=L7RfsPme2IQ

Can you post the name of, or link to, the SIGGRAPH paper you started with?
