Feature Request: A1-style Quick swap nozzle

Bambu Lab X1 Series General discussions
1

I love my X1 Carbon, but the process of swapping the hotend assembly—such as to go from 0.4mm to 0.2mm or 0.6mm depending on the needs of my print—is a bit tedious at best, and anxiety inducing at worse.

As a hobby user I find myself doing this fairly frequently, as the kind of prints I like to make vary from small detailed miniatures to larger structural parts.

So I’m not a big fan that each time I want to perform this operation I have to remove and re-tighten two screws and unplug and re-plug the 4-pin cooling fan plug and the tiny 2-pin thermistor plug, as shown on the wiki: Replacing the complete hotend assembly / Nozzle Replacement Guide | Bambu Lab Wiki

Even if I am careful, this results in wear on the screws, the mounting holes, and the wires and plugs. I’m primarily worried about the wires and plugs.


While I don’t currently have a need for the recently released Bambu A1, I love what I have seen of the Quick Swap nozzle it employs.

For my personal use-case this kind of a system would be perfect, being able to swap nozzles at any time without tools and without fear of wearing out the wires.

I understand that every design choice like this has tradeoffs and drawbacks. For example replacing the thermistor or fan on the A1 is far more tedious than on the X1, requiring quite a bit of disassembly A1 series Hotend Heating Assembly Replacement Guide | Bambu Lab Wiki

Similarly I don’t know how the thermal performance of the hotend is affected on the A1 vs the X1.


So my feature request for the X1—or potential new entries by Bambu in a similar or higher price and feature range—would be a quick swap hotend that is comparable in ease of use to that of the A1.

I am aware that some third party solutions exist, but I would love something just provided by Bambu that I know just works.

I would ideally love for this to just be an upgrade you can purchase from the Bambu store for existing X1 printers.

unplugging and plugging the tiny heater and thermister cables is a delicate operation and routing them can be challenging.

The A1 system is much much better with much less potential damage to the connectors and wires and circuit board.

I think it would serve bambu well to have an upgrade of the X1 to use the A1 mini magnetic attach system.

A1 is inexpensive but that does not mean that all features on this newer system are “cheap”…

Are there any good hot-ends that work well with the X1C and allow to easily hot swap the nozzles?

On the official part I would not mind spending extra on a new assembly that would convert the X1C extruder assembly to match that of the A1

Yeah, this is one of the big reasons that I’m just waiting on the A1 rerelease rather than replacing it immediately with one of the P1 or even X1 printers - I want to play around with some of the larger (and/or hardened) nozzles, but I don’t want to have to deal with wiring or the like.

100% agree! The X1 nozzle replacement is way harder and more delicate than the A1 nozzle replacement.
Damn! the X1 nozzle connectors are glued in from the factory!!!
Why??? Are we supposedto glue the replacement’s connectors in???

We clipped away the glue when making our first replacement but one of the sockets opped off the circuit board, and we had to remove it and reflow the solder on it.

PLEASE, BAMBU! the A1c nozzle replacement is sooo easy, and performance is comparable.
