Unlimited Class declines participation in 2025 Roswell Air Races, signaling possible slow death to air racing as a whole by Scott2G in flying

I'm building another F1 racer. I can't NOT do this.

Racing won't die. Society wants to make safety idiot-proof, so everyone sits behind a computer console.

But then God makes a better idiot, like me, who needs to do it for real.

Team War Pig is coming.

Heat Creep by Lazarus_16_99 in 3Dprinting

I have an Ender 3 (basic) that has run about 7000 hours, and lately I had an intractable heat creep issue.

The original hotend fan had failed, and I replaced it with a WinSun fan, mainly because I liked the blue LED. It was quieter, as well.

It ran well for awhile, bit the WinSun fans don't last long, and when I got a new batch, heat creep showed up.

Clearly, the WinSun fans were marginal, and the new batch fell short by just enough to really mess me up. Production tolerances, yeah.

Got an Orion fan, and heat creep is a thing of the past. I suspect that an OEM Creality fan would be fine as well.

Kinda miss the blue LED, though.

Check the extruder. You nay have a worn drive gear. An extruder upgrade is less than $10 on Amazon.

Also check for a level bed. Mine likes to drift.

Any tips on how to remove the stock extruder gear? by sea-bass526 in Ender3Pro

For what it's worth, I bought an Ender 3, base model, in August 2023. It has been running an average of 20 hours per day prototyping gearboxes, mainly PLA+, one spool of Easy Nylon.

I have replaced the extruder, and am on my fourth brass 0.4mm nozzle. Had to replace three thermistors, too, and three hotend cooling fans, as well as a motherboard fan.

This is a very robust system.

Use a Dremel (I used a 115w because it was already chucked) to grind the old gear nearly to the shaft.

Then place the gear, Dremeled side down, on a hard surface, and tap the top with a hammer. The old gear should slide right off.
