I need some help with my A1. I have a decent knowledge of Bambu printers as I have an x1c and a p1p which overtime I have replaced extruders nozzles and other maintenance with success but I am stumped on this a1. It seems that on the first layer the extruder is getting stuck. I took apart the print head today and I did not see any blockages I even put on a new hardened steel .4 nozzle, and I did update that setting on the printer. The printer seems to have no problem creating poops by extruding filament and it seems better after the first layer but on the very first one you can see the exterior clicking. Any idea? It is not wet filament and it’s not my build plate. I have tried a few times to print a simple file and the first layer is straight up trash. I took those same filament spools and even the build plate and put it onto my x1c and it completed no problem. I have tried printing a preloaded file off of the A1 and I still have the same issue. I even created a simple 2 mm disc within bambu Studio itself and the first layer is ■■■■. Any ideas?
I don’t usually do this, but…
Your 2nd video is why I asked those questions, but hey, what do I know.
So, when someone else asks you the same question…
you can give the same smartass answer you gave me.
I’m on Lion’s side, you’ve asked for help, someone asks a general question. Instead of answering, you throw shade and say it’s nothing to do with those. Whilst this might be the case, why come here and ask for help if you know more then the people willing to help?
Anyways, beyond that, any chance you haven’t set the build plate correctly. You mention it’s extruding fine when calibrating. It looks like it could be too close to the build plate? What is the temp of when it’s calibrating vs when it’s printing? Whilst it may not be the case, it may help someone see something that others don’t
Can you try a first layer print only that way we can see the extruder properly cause it should click on retractions as there is slight play in the gears.
It’s an issue with the latest firmware. How do I know? I have an A1 and an A1 mini, the mini being less than 60 days old and the A1 being less than 30 days old. I updated the firmware on the mini to 1.03.01 and this started happening. I spent hours trying to figure it out. Got fed up, bought an A1 because I had a project I was in the middle of that needed to be finished, used the A1 without issue for a couple weeks, got a blob out of nowhere on a PLA print of the scraper plan that comes with the printer…spent 6 hours cleaning my toolhead, printed fine, and for some god forsaken reason I decided to update my firmware to 1.03.01–in my mind it was to prevent the blobbing…now I get this too-close-to-the-bed problem…same as my mini with the same firmware.
I’ll also say there’s an inconsistency in the manufacturing of the hot ends. I began comparing hot ends and noticed 0.4mm stainless that came with the mini vs the a1 there is about a 1mm difference in length…possibly also a related issue, but I can say I’ve tried 4 hot ends on my mini (0.4 hardened, stainless, and 0.6 and 0.8 hardened) and continue to have this problem…which has also caused filament to get stuck in the hot end tip causing a blockage. It’s maddening.
Have you done a complete re-calibration procedure after updating the firmware? This is not the calibration the printers do before each print but the complete procedure you can start via the printer screen and which is runs when you first initialize the printer. It is also recommended by Bambu to run after each firmware update.
