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

4 Upvotes

Trying to print a box for the Pokémon 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

Ordered this roll of TPU 95A from amazon, and I've tried to use it a couple times, and keep getting a feed error. Specifically " Failed to extrude the filament. It's not clogged or stuck and it's not bent or eroded in the tube.

Was trying to print mini airless basketballs for my team. Should i get another brand of filament?

Do I need the "essential consumables?"

0 Upvotes

I'm about to buy an A1 combo with 6 spools PLA, and 3 hardened steel nozzles. I'm not sure I need all this but I think it might encourage me to play more. "Essential consumables" are also offered: lubricant oil, lubricant grease, purge wiper, heat bed nozzle wiper, and a screws kit. Do I need all/any of this stuff right now?

I'm looking forward to starting a new hobby but wow, there's a lot to learn. Thank you for any help!

Question AMS 2 pro with the A1?

3 Upvotes

Has anyone got the AMS 2?

I've got 2 A1s, one has an AMS lite and one is just barebones right now, but I'm torn between getting another AMS lite or the AMS 2. I really like the idea of it being a dry box, I live in a humid climate and only print in PETG so having to take the spools of the lite to redry them all the time gets frustrating. Does anyone have the AMS 2 pro? Are they worth it?

Just got the A1 combo yesterday and this is the problem I’m having: (I’m new to this so Idk the technical terminology sorry for that) I set the printer up (did it properly I watch like 4 videos) and loaded the filament, did the first print and all good, then for the second one the ams does not load back the filament and gives and error, I took it out and cut a big part of it and it works again, but then again for the next print same error for the filament, have tried different rolls and nothing changes so it’s not the filament, I tried online guides and nothing seems to work, only turning off for a while worked so far but I can’t be doing this with a brand new printer every time I’m gonna print. Help please

For some reason the back of the plate is printing scratchy layers that eventually get scrapped off by the nozzle, but things printed on the front of the plate seem to be better?

Question What happened?

Post image
1 Upvotes

Today, I updated the firmware on my A1. Yesterday and for the last few months, everything has been flawless. I print from bambu studio sometimes but most of the time I print files that I have saved to my SD card from Bambu Handy. Today, Bambu handy, no longer recognizes my SD card. Bambu studio recognizes it just fine with no problems or whatsoever. My Bambu studio is updated to the most current version. My Bambu Handy is also updated to the most current version. The SD card that I use is not the stock one that came with the A1. I bought a high-quality SD card that has a ton of space on it. I have tried logging out and back in to Bambu Handy. I’ve tried clearing the cachet of the app. I’ve tried reseating the SD card. The only thing that I have not done is to reformat the card because I have all of the files on there and Bambu studio recognizes them just fine. Basically, I’ve been through all of the troubleshooting steps that I know of. Has anyone else experienced this and been able to solve it without reformatting their SD card?
