What is the correct procedure to shutdown the extruder?
MK3S
I have used up my first roll of filament and thought that I should load up the next roll to get ready for a future project, so I heated up the extruder, unloaded the remaining/existing filament, and loaded up the new filament roll. All went well.
I might be missing something, but I could not find a way to turn off the heating function of the extruder.
I didn't want to turn off the main power because I didn't know what damage might happen to the extruder not being able to cool down slowly using the fan.
I decided to load up a file, start the print, then stop the print, which allowed the extruder to cool down slowly with the fan.
So, if the printer shuts down at full temperature, and has no cooling from the fan, does that cause any damage or premature deterioration of the extruder.
Thanks to All that reply.

You are doing it the right way, but the hotend cooling fan will come on if you do a reset and let it sit for a bit. Just a bit quicker. There is also a safety shutoff if the nozzle is held at temp without movement for an extended period. I'll admit it: I'm lazy and just hit reset after removal. If you set up octoprint, you can use the nice web interface or even write a little gcode snippet to initiate filament removal.

The "preheat" menu has "cooldown" as the last entry.
(Or, settings->temperatures, dial it to 0)

Thanks @bobstro, too old to start learning code, learning Fusion 360 already fills my tiny brain.
Thanks @vintagepc, did not see the "cooldown" in the "preheat" menu. Thought I might have missed something, but was looking for something that indicated cooldown, not preheat.

Nonsense! Just tell yourself that it's your 1st 1980's 6502 board that came with the OS source code. It's reminding me of disassembling Apple II code by hand. I must say, gcode and Fusion 360 certainly cover the spectrum of complexity. Throw in a slicer for good measure and the old hamster wheel is really creaking along!

I think these printers are too damned powerful myself. I miss the simpler times...

Who's gonna be the first to dangle some TMC2130s off a Commodore 64 and have it drive one? 😀

Times when the schematic drawings met the size of the actual electronic board 😉

Gotta hate it when you walk away from a big print only to realize later you forgot to press PLAY on the cassette drive.

Never thought about that before, but that's definetely a marker for one of the times "things changed". Not necessarily for the worse, but our relationship to hardware shifted. I love opening the old books and finding the fold-out schematics... Because you could fix things back then.

Is that an S100 buss card edge on that KIM 6502?
Damn you are OLD!!!
TTY teletype 6502 and Z80 early 8080 stuff for me. I am that old too. EEs rule. (Electrical engineers)
I am the inveterate tinkerer. I can tink up most anything.

It's actually a board I bought 2nd hand as part of a never-completed project. It still worked as of a few years ago, but I don't have the energy to poke in 6502 machine code anymore. I actually cut my teeth on an Apple II+. Did the whole acoustic coupler @ 300bps thing. No EE here, just an enthusiast!

Dang - you guys are going to make me dig out my EVM and handful of CPU's for it and my assembler. All just for a photo. In my case I was developing the RT firmware for an oscilloscope. And used the tools later to control some custom test gear. Go figure. As for my C64? Where else did everyone learn BASIC? But honestly, I can't remember if I had a Commodore or the later C64. Loading code from cassette tape was just plain ugly.
RE: What is the correct procedure to shutdown the extruder?
Pulling the tub with the EVM is going to take a few minutes ... but now that I see eBay sellers are hawking used chips for $8 each, and I have several essentially unflashed "new" plus the EVM (also serves as an emulator!) and assembler if someone can read 5.25 disks ... I have a new project. lol.
RE: What is the correct procedure to shutdown the extruder?
all you youngsters - started on teletype ASR33 and 35 and really old computers - pre PC - first computer i owned was an Altair 8800, worked for DEC on Decsystem-10s, and later on link simulation Mark1 discrete germanium transistor based computers ( pre IC). still in flight simulation and we still have machines running on DEC VAX hosts and others on motorola M88K based SBCs and others on AIX Power RISC servers.

And looking back at history; I had the VIC-20 ... lmao. As soon as I saw the name, it clicked. The audio level had to be "j.u.s.t ... r.i.g.h.t..."
What's weird is I recall owning it in the 70's ... before I started real programming on 4052's.
RE: What is the correct procedure to shutdown the extruder?
Those were so advanced. My first computer ---- the Geniac. We didn't need no semiconductors!
RE: What is the correct procedure to shutdown the extruder?
Yeah - VAX's and cards. A colleague was few years my senior was active in keeping the finance department running. PDP 8's with core memory and punch tape was about my first "real" computer experience. Loading the boot loader with paddle switches just to read the punch tape off the teletype ... lol. Later years the 5MB hard drives the size of washing machines ... even had removable 24" disks.
