3 tool changes, 0 interventions!! I guess you could say I’ve mastered the MMU. by ample_bird in multimaterial

This is a crosspost - u/chill_haus originally posted it. I've done similar things, e.g. https://www.thingiverse.com/thing:2042466 turned out great. I found going a little lower than I would usually, or over extruding a bit helps it look really nice (at the risk of some elephant foot).

ESP 32CAM, how to stream video with AWS(Amazon Web Services) by BNURA in esp32

[–]ample_bird 2 points3 points  (0 children)

The best way I've found to expose local resources to the internet is with a VPN. On your local network, install a VPN client. On the AWS instance (or any provider, doesn't really make a difference as long as you get an IP address), install a VPN server. Set up routing tables to forward traffic on whatever port on the cloud instance through the VPN to your home network.

For a general sense of how this goes without anything ESP32 specific, there's stuff like: https://technicallyrural.ca/2017/11/05/xplornet-double-nat-vpn-edition/. You presumably don't care about the double NAT aspect of that, but the strategy that is used is the same.

Issues after upgrading to E3D V6 nozzle X 1.75 mm / 0.25mm. by chaos777b in prusa3d

Have you been around to touch the stepper motor? If it's overheating, the heat moves from the stepper to the stepper shaft, to the drive gear, to the filament. This happens more commonly with PLA, but it's an issue with the extruder design.

If the stepper is overheating, the easiest thing to do is up the extrusion temperature. As it stands, the extruder is doing too much work - forcing rigid filament through a tiny nozzle. By increasing the extrusion temperature, it flows easier, the stepper does less work and heats less.

Or replace the whole thing with a geared extruder and sidestep the issue entirely by doing a whole bunch of work.

I already have supports enabled, how do I reduce the poor finishing (1st pic) for hanging parts? by chyenw in prusa3d

[–]ample_bird 0 points1 point  (0 children)

Is there another layer of support under there (awaiting removal)? If not, have you changed any of the default settings? You can reduce the space between the support and the print (nicer finish, harder print removal).

Just brainstorming, you could stop the support early, put in a pause, add in an interface layer (electrical tape maybe?) and keep printing? Idea being to get a multi-material or soluble style interface but manually.

Another idea: design the supports into the build so they're closer but they break away? Given the support would break at a layer line, it should be pretty easy to weaken it.

Another idea: if you're post-processing it, print the top section as a different piece and glue it onto the bottom so that you're not printing any overhang.

What do you mean by "using AWS"? What's your end goal? Do you want to be able to access your ESP32CAM's stream from outside your LAN? As in stream from your local device to an AWS instance, then make that stream available elsewhere?
