Random 3D printing chatter

Good luck. Hopefully something isn't bent. Could be a limit switch bent/missing? Can't remember (and can't be bothered to go look) how they've implemented limits on the mini. Hopefully it isn't done on strain (motor can't push it past actual stop and the resistance is detected as limit) as that could show there's a sticky point on the rail it's interpreting as the end.

A factory reset seemed to sort it, and new purge cutter arrived today :)
 
I watch quite a few YouTube videos about 3D printing, I especially like the more technical channels like My Tech Fun but I also like the more mainstream stuff. I’m currently looking at getting into more technical filaments and watching some videos about PET-CF as I think I’ll start there.

One thing they all do that really annoys me is handle build plates without gloves. Why oh why don’t people put some gloves on? Yes I know you can clean the plate after handling it but wearing gloves means I don’t have to clean the plate as often.

I need to get out more.
 
You do....need to get out more! ;) :p
I mostly scrape prints off with the Bambu scraper blade on a printed handle. Those I need to flex, I only really handle the edge of the plate so it doesn't really cause a problem. As you say, worst case a wipe down with IPA sorts it out in less time than it takes to, well, put on a pair of gloves. But hey, if it works for you and makes you happy, it's not wrong.
There's some good content in the MyTechFun but it's very dry and a hard listen.
PET-CF is good if you need the heat tolerance. Pricey though. Have a look at PETG-GF by Tinmorry if you don't need the high temp tolerance. It not quite as stiff but it's a darn sight cheaper and prints beautifully.
 
So printer all back up and working.

Have some PETG arriving today, apparently its “harder” to print with, but I’m assuming that being a Bambu, if I get a file from maker world designed for PETG I’ll run into minimal problems?
 
PETG is no harder than PLA on a modern machine. If you've got a naff extruder at the end of a Bowden tube and hence can't get retraction right, it can be stringy. Bambu's all have direct drive (extruder in the print head) so you'll be fine. The nozzle and bed temps need to be higher and the speed, cooling and retraction settings need to be different...but either Bambu Studio or Orca Slicer will take care of that for you once you tell it what the filament is. The only thing you might need to do is print a pressure advance calibration pattern so you can set that for the filament. If it's a Bambu filament, it should be pre-set.
Sunlu works quite well for PETG if you haven't already got. The only complaint I've got is their grey is a bit unevenly coloured but prints fine.

PETG can be a bit more hygroscopic than PLA so if you find it later starts stringing or snapping (can get brittle) it might need drying.
 
Speaking about PETG, and other filaments, what are peoples opinions on tweaking the stock profiles, or just downloading someone else's profiles?

I always use the stock profile as a base, then calibrate to the filament and save it out as my own version, but you see a lot of people just randomly downloading other peoples profiles and then running them, not knowing whats been changed etc, makes no sense to me as I'd like to know what I'm asking the machine to do...
 
I print a lot of PETG, it’s so much easier to print than it was when I bought my first 3D printer.

When I download a 3mf I check what’s different from my standard profile as that’s easy given Bambu Studio highlights what’s been changed. I’m sure other slicers do the same.

Same. I tend to tweak the profiles for say Gyroid infills, Walls and sometimes Print by Object if I'm low on filament. If I am printing large prints that have a wide base then I'll lower the speed of the Aux fan on my P1S as that thing is a PITA a lot of the time and can mess up larger prints.
 
The default bambu filament profile should work fine, although you will be able to increase the print speed by tweaking it yourself as the bambu profiles tend to have low max flow rates set by default. I would just try a test print and go from there, its easy to print with, especially if you buy the rapid pet-g filaments.

I've ordered a Creality K2 Combo (K2 and 4 colour CFS unit). Coming from a 3 year old Ender 3 V2 Neo which seems to clog a little on tricolour silk filaments for some reason, I'm going to put a new hotend and spring plate on it and give it to my eldest daughter, she has shown a bit of interest so will see how she goes.
Anyway, I watched plenty if videos on the three main contenders, P1S, K2 and Anycubic Kobra S1 and it seems this is the best available (without horrendous backorders) all rounder, hopefully I haven't made a huge mistake as I've enjoyed the Ender 3 so far and the learning curve with 3d printing.

I'm thinking of getting a P1S + AMS.
Not had a 3D Printer before, also not really sure what I'll do with one.
How easy is it to design your own things rather than just use things someone else has created?

As people that have 3D Printers do you think I'll find things to use it for once I have one or if I don't have an expected use am I unlikely to find one? It's a lot of money to just sit around gathering dust.

I was considering an A1 with AMS but my understanding is that due to the printbed moving it requires more space than the P1S, is that right? I don't have a lot of space so need something reasonably compact. Also humidity is a concern so I thought an enclosed AMS like you get with the P1S would be good. Is humidity/moisture a real concern with filament?

You will need to do some learning to design with fusion360 (free) or tinker and etc. but to pro t downloadable s is fairly straightforward forward and you will learn some of the terminology quickly like infill, ironing, skirts, supports etc.

Absolutely, printing everything from terminator heads to shelving brackets to desk tidies to lamp shades and everything in between.

Printers without a moving bed tend to print faster and more stable output I believe as there's less shaking overall going on. For humidity, if it's excessive you will get a poorer print often with awful zits. You can use a heated AMS/CFS or use desicated silicon sachets in there if it's a non humidity controlled enclosure.
 
Do these things make a constant noise when making something?
I keep hearing this irritating low noise coming from my neighbours, it goes on for absolutely ages.
It’s not actually loud in anyway it’s like a low pulsating noise, at first I thought it was a washing machine or something but I’m thinking it could be a 3d printer.

I’m not bothered enough to mention it really, just wondering if these things are noisy generally.
 
My old Ender 3v2 neo runs at the far end of the living room extension, the only thing you can hear is the hotend fans running but tweaking them down from 255 to 220 or less virtually silences them.
 
Finally got my P2S a few days ago and I'm loving it! I've only opened and used a pla spool for now but need to think about drying some petg and abs which will mean storing pla. The printer is in a garage with a fair amount of humidity so I'm thinking of storing in air sealed storage box with desecant to keep moisture low. I've seen a lot of people use cereal tubs but I'm thinking of maybe storing four filaments together or maybe more and sticking the box on a shelf in the garage. What are people here using for storage? Any advice on what boxes work well in the UK so I can go and source a couple

Have you considered getting a dehumidifier for you garage?

Good question, I haven't as it's not very air tight if I'm honest. We've improved it, but still quite a lot of outside air creeps in. Were you going to suggest just storing on a filament shelf or similar rather than enclosure?
