Is my Ender 3 Neo gonna care about printing in a cold garage?

Paradoxish posted:How cold? I've gotten away with printing PLA as low as 50 F and had okay results, but you're risking a lot of warping and bed adhesion issues once you're down at that point. It's not going to be quite as finicky as resin, but you do want to try to keep it somewhere around 60-ish at a minimum, and you don't want any drafts. Talking 30F today so maybe 40-45F in the garage. No drafts, really. Even a heated bed won’t really mitigate this? I guess I can make it an enclosure and let the bed warm it up good before it kicks off.

It would basically have to be maxing out a 15 amp circuit 24/7 at ~11c/kWhr to hit $100/mo. OK, so cold is less than ideal. What about heat? Do I care if the garage is pushing 100F?

1> Use .gcode to travel print head to each corner/center, and manually level bed 2> Run auto leveller 3> Double check and adjust z-offset 4> Run the .gcode that prints concentric squares to confirm evenness 5> RUN AN ACTUAL OBJECT AND WATCH THE FIRST LAYER LOOK LIKE UNEVEN poo poo Why??

BadMedic posted:IDK what printer you are running, but you might need to add a 'load the bed mesh' command into your starting gcode in your slicer. Ender 3 neo. G28 disables homes and then... disables bed levelling? That's weird. And there's no following M420 S, I'll try that. I wonder if there's a setting in Cura to say hey, auto levelling is a thing on this machine. There's no preset for the 3 Neo. edit: oh man, even the Creality-wrapped Cura doesn't include the M420 S command, how bizarre.

Sydney Bottocks posted:As far as I know, there isn't a setting in Cura that tells it to use the saved bed mesh. I used to have that gcode command in my Cura print start gcode section, to tell it to home and then load the saved bed mesh before starting the print, but AFAIK there's no option you can check or whatever to tell it to do that. Well I also discovered that the non-driven side of my Z-axis rails had some not-insignificant slop and tightened that down, now I think I am getting a bit of banding. We'll see when this print finishes. This stuff is.... a chore.

Is bed leveling and offset just impossible? Manually level, print concentric squares, everything’s flawless and even. Great. Actual print? Nozzle gets right up against the glass for part of it til it can’t even extrude. Just awful. What gives? Ended 3 Neo. Is it the stupid auto leveling thing? Can I shut that off and have it not try to compensate?

Yeah so I just cleared the BLtouch data, meticulously leveled my bed the old fashioned way with a piece of paper, and then had it print some nonsense while I manually tweaked the z-offset. Easy and works well now. I have a glass bed. It ain’t gonna be substantially out of flatness. Screw this automatic crap. At least this variant.

Hm, long print, had a few spots where I got this kind of thing across an entire layer. That's very zoomed in, this was on .12mm layers. It almost looks like there wasn't enough plastic flow? Anyone know what this is? I almost wanna say the gears had trouble feeding filament like maybe it was jammed up or something?

Nerobro posted:Hmm.. why does that smell of 2a? Let me clarify after re-examining, the ridges are actually protruding and rough, visually it kinda looks like gaps, but there's definitely very fine raised lines there. It's weird, it went through several inches of z-axis that are perfect glassy smooth but then this occurs now and then. Dirt on the Z-axis screw threads causing hitches where it's not quite raising a full layer height? Maybe some light oiling? - Ender 3 Neo - 50mm/sec - Retracting 6mm@60mm/s - Using LOTTMAXX 1.75mm PLA. Lists temps at 190-230C, I am at 223 right now. I wonder if there could be some element of a layer where a particular movement pattern or the length of a path could lead to some kind of temp issue. I probably should do better logging in Octoprint. - I worked all last week dialing in X/Y/Z and the extruder. I haven't seen any banding like that before, but I am usually doing small scale stuff within a couple of inches from the bed. These cubes never had anything but smooth surfaces using the exact same temps and flow:  Their corners seem kinda sloppy and bulgy and I know there was some bad elephant-footing on some that I fixed. Other than that, nothing weird or new in the slicer settings. I am printing something much more detailed and complex right now and I am noticing some light stringing, but I can't tell if it's mostly in the supports or not at this point, the print that started this chain had no noticeable stringing. Are temp towers actually useful for diagnostics? I could probably come up with a real easy torture test of an inch wide vertical wall to see if I can replicate and try bumping temps up and down to see if I can replicate. Regardless, I hadn't seen that guide before. Looks dense, I will read it.

Roundboy posted:You need more top/bottom layers because your infill is showing through the print I will try this. Also, I remember I cranked up the retraction because of some stringing, but in retrospect I may have just not had the temp high enough for that filament.

That top layer surface looks like you’re underextruding a bit.
