Mods I recommend

Filament 3D Printer Technical Help Bambu Lab P1S
1

I have had a P1S for a little over a year now and found a number of things it really needs. I dislike modding printers but sometimes the original design is bad and needs help.

PRINT an ams buffer tool! You will need this and you cannot service it with out one. there are a lot of models for this.

I would recommend a top glass riser with vents and light. It eliminates the need to open the top (my AMS was on top and opening the top glass for plastic is a nightmare.) I walk past the door and leaving it open was just asking for unclejessing it. the light addition makes it so much better to see.

Add a high flow nozzle. My bambu could not make glossy prints unless you slow it down 50% the nozzle is just barely able to keep up. A drop in replacement like E3D or diamondback solves this. (I use the E3D).

AMS its a nightmare to use other manufacturers filament. If you plan on only using Bambu esun filament ignore this. I don’t love the bambu filament its ok no issues but its expensive for its quality. There are filament I thing print just as well for less money and ones that print better for the same.

I am in process of a full python change to the AMS. I am hopeful this will stop motor issues, over heating, miss feeds, jams I have had for most prints. The AMS is a mess or at least mine is.

That is my suggestions for Bambu fixes. These solved my repair, heat creep, print issues, and I am hoping all the feed issues.

I really wish Bambu would respond and fix the design. The buffer tube is silly, and no vents that can be opened or closed is not a hard fix. Hot end I get. AMS also as much as I hate the walled garden. They are close to the best machine but they just get in their own way, if it was easier to work on and a few daft ideas corrected.

Python AMS Update

I have finished the Python and have run about 3 KG though. Give or take. So far it has run all cardboard, sample spools and weird undersize spools (great hobby) It has not had any pull back issues or jumping spools issues. It has run reliably so far. Well worth the time and money I invested.

I am really saddened to see retailers switching from cardboard spools to plastic because of Bambu design moments. I don’t love Bambu filament or eSun for that matter, its not bad its just not my fav and paying an extra 10$ for a chip is obnoxious. The python looks so far to eliminate this.

Just a quick update three months down the road. I have run around 20 25 KG through the Python. There has been at least 2 design updates since I finished mine. Its good to see especially as Bambu have not fixed the glaring design flaws in years.

I have not had a single issue with the Python over the 20 kg of filament run through it. Aside from a couple of rolls having the filament not release from the spool core it has been flawless. It has handled cardboard spools, small super heavy mdd spools and weird sized one, tails of filament too. None of these would have worked in the original AMS.

It is well worth the ‘mod’ (re construction really) I built the enclosure too and it is doing a far better job of keeping things dry too. All in all one of the best alterations I have ever made.

20 KG what, a slow month?

lol Big project. I also have been running all the ends of rolls. The old AMS didn’t do well with the last 1/4 of the roll so were tons of them sitting round.
