Random 3D printing chatter

Thanks, i have got most of those bits will look out for a engineers scribe as that looks perfect.. I also hear that sanding using an emery board used for nails are pretty good as well where a file is not needed.
 
My new printer which is replacing an A1 mini arrived. The mini was great but I was having issues with PET-G adhesion due to warping from draughts etc, I thought about building an enclosure for it but by the time that was done, it would be bigger than just buying one of these. Printing with the enclosure closed on this and I now have 0 issues and can lower the bed temp by 20c.Its a lot louder than the mini but replacement fans are on the way from China to cut the noise down, so far I'm really happy with it for the money.
I was worried about losing the bambu app for remote monitoring but I've discovered and set up OctoEverywhere and it's a more than suitable replacement.

Can you let us know how you get on with the replacement fans please? If they are any good the model numbers would be handy as well. The noise is the only thing I can complain about on my Centauri Carbon and I have stuck it in a cupboard where I can't hear it so much for the time being.

Sure, the two I've ordered are:
- Mainboard fan 24v 8200rpm- SUNON 4CM KDE2404PKVX DC24V 1.5W 4020(3 pin)
- Chassis fan 24v 4000rpm - https://www.ebay.co.uk/itm/405699800061?var=675986991142

The stock mainboard fan is around 12000 rpm based on the specs, so the replacement should be a fair bit quieter. It does look like it will need the connector from the stock fan swapping onto the replacement though. Ill take some pictures when I do it.
 
As it happens my Centauri Carbon threw up a serious error message overnight relating to a fan. I tested them all and they all seem to be working but the print is "warped" is the best description I can come up with on one edge so maybe something was too hot. Anyway, it looks like I am going to replace the lot as a precaution.

Sold my H2D and ordered an H2C. It was cost neutral to do it this way vs buying the upgrade kit. This way I get a new machine and don't need to worry about breaking it when I do the upgrade.

Wow. If i was in the market now for a printer i would just stick with bamboo. Yes its double the price but piece of mind
 
So would I but at the moment it all seems highly confusing to me.

If anyone is looking for a dryer the Sunlu S4 is a cracking £106.99 on Amazon and sold by Sunlu themselves, that's much cheaper than their own website. If you only need a two roll dryer the Sovol SH02 is only £49.99 with free delivery from Creality. I just bought this one myself.
Are these good now? I seem to remember there being issues with the sunlu driers that they didn't really dry properly, at best they just kept dry filament dry. Ive just seen the AMS 2 which looks pretty good but I already have an AMS for my x1c so don't know which is worth it. I'd been using the oven on the warming setting overnight up to now.
 
The Sunlu Filadry single-roll (S1?) didn't have a fan, it just heated the filament. The S4 has a fan and it does work. The AMS2 has two features I think (on paper - I haven't got one) are improvements over the S4: it rotates the spool during drying (not sure if continuous or at intervals) which ensures even drying - although you can of course do this by hand - and it vents the moist air periodically. Again, you also do this inadvertently if you rotate the spool by hand so it's down to whether this benefit outweighs the cost. That said, the AMS2 is also an AMS so if you're in the market for an AMS and a dryer, it would seem rude not to get an AMS2. The HT version is also interesting for more engineer'y filaments but only a single roll.
 
Thanks, I think I might treat myself, the auto rotating does seem pretty sweet.
Might have to see about selling the original AMS. Yes the HT does also seem really cool, I do have some fancy filaments I've not opened yet because I never got round to sorting out a way to keep them dry

I wish I could tell you that you were alone in that but I have what is probably approaching a collection:
ABS: Had to have some now I have a printer capable...and have not yet found a use where something else isn't easier and at least as good.
ASA: Bought because it was better than the ABS I probably only bought because I'd previously been told I couldn't print it. Have printed this and it's a pain...but I needed the colour! :cry:
ABS-GF: Solves most of the problems of ABS and is fantastic...and still in the box because then along came PETG-GF and it's easy, cheap, UV resistant, fairly heat resistant (compared to PLA), strong and prints beautifully.

I printed some PLA the other day because I need to prototype a piece of something - it's the model functionality that's important, the print is then disposable (unfortunate but better than wasting the entire thing out of solid acrylic). I'd been telling someone it was easier for beginners and yet it peeled off the bed, it warped, there were hull lines and the entire thing was an embarassment. To be fair, it could be PETG residue on the bed that'll need washing with Fairy to remove that caused it....but then I went back to PETG-GF for a storage box and it's perfect - like faultlessly so. Well, admittedly it was the 2nd go because I ran out about 15mm up the print. Another spool in the AMS to continue to you say? Yes, absolutely. I checked it at around 15mm high and went to bed (yes, I know this is unadvisable but the concrete room it's in should be ok if the worst were to happen). 12 hours after starting it I checked it and .....11 hours of air printing *facepalm* The very end of the filament had a slight kink in it where it came off the spool. That got jammed in the PTFE tube from the AMS to the buffer and everything reported filament present whilst the gears wore down just one section of filmament for hours *sigh*

I've not even heard PETG-GF was a thing, sounds perfect.

Hello I'm shroomz and I'm also a filament addict.
 
Brand is Tinmorry. The black prints perfectly. The grey is significantly lighter than it appears. Both the white and grey weren't as faultless but were pretty damn good, just a couple of zits along a vertical seam...and to be fair, I'd tuned for the black.
I run it on the Bambu PETG-CF profile but with the nozzle turned up to 280°C and the bed to 80°C. My bed is quite a thick G10 bed so needs to be a little hotter than stock but gives fantastic results with no glue. I believe that you can print with a nozzle temp as low as 260 but I used the temp someone else suggested in a review and I've had no reason to change it - it doesn't ooze or string so why mess with something perfect.
Pressure Advance (K) is 0.026

It was the latest firmware at fault, it also turned off the heater for the printbed which turned things into a spaghetti nightmare!! I contacted Elegoo and support got back to me in under two hours with a download for firmware 1.125 and since I flashed it back everything has been fine although I have lost some features and I have to get used to the UI on the screen looking different but at least all prints both long and short are fine now.

I also have a bit of a filament addiction. I have 22 spools in the cupboards plus another five on the way, god knows where I will put them!! I just keep finding cracking deals and can't resist buying some more.

The answer - at least temporarily - is to 3D print some filament storage. Two birds, one stone and all that. The brackets for those shelves are all PETG-CF and all the spool mounts in each container are PETG plus four cheap bearings.
Permanent answer? Well, clearly not as you can already see stuff stacked on top and some of its in the way of an Index Lighthouse at times : rolleyes: Mind you the mount for that is PETG too :D
