3D printer choices

[Tony Pratt 1Participant @tonypratt1]

‘Damp’ filament issues are very prevalent across all the 3D printing forums I look at, I’m in Bedfordshire, printer is in a spare centrally heated bedroom, I print only PLA at the moment and use desiccant in the AMS [27/29% RH] with no pre drying, I’ve had no issues thus far but a dryer is on my list.

Thanks for the further info, Tony

I may live to regret this but, I bottled-out of buying either version of the AMS and bought just the Printer and one reel of Black ASA filament.

Exciting times ahead …

Once again the forum software has prevented us from seeing your excitement!

Presumably it doesn’t like .png files

… it was just a small clip from a screenshot, showing the three available options.

Oh dear, what a mess !

After a successful self-test, followed by a firmware update, followed by a 26 minute calibration run … I finally got to choose a test file to print; and selected ‘Screw Gauge from the list.

I think it took 1 hour 44 minutes to produce this worthless heap of scrap plastic.

🙁

Any advice would be gratefully received.

Oh dear. Is the nozzle temp too high?  (not that I have much experience yet!!)

I’m surprised it took 26 mins to calibrate.

Not sure what slicer you are using but assume you have it matched to the filament you are using….

[Michael GilliganParticipant @michaelgilligan61133]

Thanks, Matt … I need to try again, with some smaller files

I may have set something wrongly, but I think not.

No slicing done by me on this one … it’s ready to go as one of the sample files.

Filament was the sample reel provided with the P1S … fresh out of its sealed pack.

It all sounds so easy in the little booklet 🙁

I have only used pla filament. I think it is recommended for beginners .

Only had a problem once when the first layer came unstuck from the bed.

Perhaps you need to change the settings. I notice on the screenshot it says suitable for pla, so may need changing for asa.

[Michael GilliganParticipant @michaelgilligan61133]

Sorry I wasn’t clear, Stuart

… I am currently using the ‘starter spool’  of green PLA that came with the printer.

P.S. __ adhesion to the bed seems absolutely fine … sticks as it should, but  lifts without too much effort,

Here’s a crop from that snapshot  I posted earlier:

… and I believe it’s supposed to look like this:

I’d say hot-end too hot, or cooling fan not working.

Looks like a serious case of under-extrusion. Check for clogs, slipping extruder and filament jams.

[Michael GilliganParticipant @michaelgilligan61133]

Thanks for the comments … although I confess to being bewildered by Fulmen’s

… the bad areas look like dripped candle-wax, which suggests to me an excess of material rather than a shortage.

Whatever … I am perfectly willing to accept having made some stupid ‘operator error’ and I will need to proceed more carefully.

 

It may be a few days before I get back to this.

[FulmenParticipant @fulmen]

It’s hard to diagnose something from a single photo, but look at the cross hatched flat sections. It looks like half the surface is missing, suggesting under extrusion. Should be simple enough to confirm with a scale, the slicer should provide the theoretical weight.

How does the nozzle look?

[Michael GilliganParticipant @michaelgilligan61133]

I take your point about the about the missing surface layer … the model that I linked is clearly fully skinned !

This was the first run on a brand-new machine … everything [except the result] looks perfect.

Urgent domestic chores to do now, but thanks for the suggestion about weighing … I will do that this evening.
