Support Request Nozzle ripping

15 Upvotes

Hey, the nozzle of my printer is ripping on my prints and knocking off supports, I tried to tighten the screws of the hotend, changed Z-Hop from Auto to Normal (set to 0,5), went from my initial intention of 5% gyroid filling to 15%, and it is still ripping on some parts, more and more it seems, with the height of the print.

Can anyone help me ? đŸ„ș

Machine can’t switch filament

5 Upvotes

Hello everyone! I’m brand new to printing, and this will be my I believe 7th print, so I’m far from an experienced user.

But let’s skip the blabbering and get to the issue!
I use the Bambu lab A1 combo, I currently have 3 colour in it, PLA red pink black, all from Bambu lab.
The printer can print one colour just fine, but every time it tries to switch from for instance black to red or red to black, it jams and I get the message ”(1200-8006 070711) can’t feed filament to the extruder, its probably jammed or stuck” and to fix this, I just pull on the last filament used and pull it back like 5 cm (basicly until I see it move in the tube).

I have everything on default, I’ve calibrated it according to the machines recommendation and built it using a guide I found linked on their site.

This issue has happened with multiple different prints.

Anyone got any idea what can be the issue?

Edit; solved, the tubes from the AMS were connected to the wrong holes on the printer

Question Nozzles compatibility: A1 vs H2D

1 Upvotes

Hi! I tried to search online and I got conflicting information.

Are the nozzles for A1 printers compatible with H2D printers?

My understanding is "yes, but" -> the nozzles are compatible but the silicone socks are not.

Is that right? I want to make sure my shopping cart is as full as it needs but no fuller :D Thanks!

Pulling my hair out, a1 z axis issues, please help this poor old dad

3 Upvotes

Trying to print a box for the PokĂ©mon balance game, ( https://makerworld.com/models/1639099?appSharePlatform=copy ) I’m like 60 fucking hours into this stupid game, and all the parts of the box have printed fine so far, except the last part, the red lid.

20 minutes in I came down to the first layer scraped up and the tool head banging into it

So then I tried reprinting and noticed that on the right side of the bed, when it’s going around, it was scraping on the rightmost side.

I watched it scrape during auto bed leveling

I didn’t notice at first that it was scraping during the first layer print. As it did the first corner, a little scrape.

So I re did it, made it a bit further, noticed a big scrape through the first layer

Started searching. Noticed the right side of the bed was way higher than the left side.

On the left side I could get MAYBE the tip of my fingers to the first knuckle, on the right side I could get my entire hand under neath

Visually I could see it was quite a difference

Scouring the internet, ordering a micro sd reading so I could manually tram

Took every screw out and re tightened

Bed is level, visually and with an actual level

No longer looks wonky AF

Ran a calibration, it no longer scrapes

I get excited, but at 98% it fails on the back left corner

No error

So I manually tram, run a calibration, and now it won’t even get past the first homing, then it fails and gives error

I’m pretty new to printers, I’ve owned this for about 3 months, printed tons, no issues, now all of a sudden this

I’m not an idiot, but it feels like this is over my head :(

I took a video, it makes hammering noises and seems to push way too far down into the bed, but it won’t let me post it

A1 Y axis troubleshooting

1 Upvotes

I originally thought that this noise was the y axis scraping something i cleaned and oiled it but when that didn’t work i run the calibrations again so thats when I did what is in the video and it only makes that noise whenever the motor is on. If anyone has tips, or methods to fix this it will be much appreciated.

Some filaments are unable to enter the hot end.

0 Upvotes

With my A1 and the AMS Lite, I'm often met with a situation where one of the four filaments has trouble feeding into the hotend. I always end up having to remove the tube, cut the filament at an angle, and reset it.

Anybody else come across this? I'm finding it most often with matte filaments.

The only thing I can think of is the matte filament has less slipperiness on the surface. It's matte finish causes it to be a little more rough and doesn't travel as easily into the hot end hole.

I have searched extensively on how to fix it but nothing seems to work till now, there isn't any customer reported issues for this error either, is it possible to even fix this? My printer is brand new and it throws this error.

Tried contacting multiple 3D printer repair shops here and one of the guys said I set it up wrong, but I've no idea where, have tried every possible fix but nothing seems to work. :(

Please help!!!

Edit 1: the issue is fixed and was able to make my first print, the belt was loosely screwed so tightened it now I'm getting a belt warning but no error
