Is it my imagination or has Snapmaker abandoned all previous Snapmaker machines, to support the U1?
GMH
No, this is correct and was announced by the stuff as they presented the u1. But you still get support from them and also some spare parts.
But yes, they have cut off their roots of 3in1 machines. They still try to be for āMakersā but in the end they focus to conquer the printer scene with their affordable multi extruder setup. 
Thereās still a market for the 3-in-1 machines, but mostly as 2-in-1 machines (laser and CNC) because the 3D printing system is outdated. Bed slingers are bad when youāre doing tall prints because the Y-axis has to be slowed down for tall prints to keep inertia from knocking them over.
Keep in mind, at least the community is still here for you. 
While we canāt really add new features/tools/etc. (except those doing really advance hard-mods, props to those users!) we can always try helping troubleshoot. We also try to find easier/better ways to use the hardware given. Donāt give up on the hardware because Snapmaker did, just ask and poke the community and weāll be there for you.
Thanks!
The 2.0 got a longer run than I expected. The Original was killed pretty much the same day the 2.0 finished itās kickstarter fulfullment. I expected 2.0 to get the axe when the Artisan launched, and was surprised that it stayed relevant until U1.
I see that J1, 2.0, and Original arenāt mentioned on the store at all. Just Artisan and U1.
Be nice if they open sourced the touchscreen android app too, as itās unlikely to gain any love this decade, and allowed developer installation of unsigned firmwares (maybe possible as I forget what was in the developer touchscreen menu)
Yes.
It has been abandoned.
Itās rarely updated, and a huge number of improvement and feature requests posted on the forums and GitHub have been largely ignored. Some bugs and pointless performance-optimization firmware updatesāwhich, if implemented, would only shorten the lifespan of the rails and cause instability in printingāhave also been left unaddressed.
Development has now come to a halt.
I believe there is still demand for the Snapmaker 2.0.
Itās about implementing features and addressing usability issues.
Things like being able to change the XY origin, or the inability to adjust the crosshairs or alignment based on the laser typeā
these are software improvements.
If custom firmware becomes available, I think it will gain popularity as a machine for enthusiasts in a different sense.
As someone who owns five Snapmaker 2.0 units, it feels like the current Snapmaker is essentially ignoring the 2.0 model.
Itās very sad.
Iām looking forward to next year, when todays frontier AI models are cheaper, and the community can retrofit accelerometers and other hotends / toolchangers, and fix the pause-resume and improve various UX issues. I almost got into the touchscreen fixing this weekend, adding a 15x15 calibration grid, but then got lost in the vibration damping firmware rabbit hole.
For now Iām mostly retiring my two A350s from printing and getting a Bambu A2L with AMS, although I considered the U1 (it was nice at KS pricing) I worry itās double the cost for features Iāll rarely use (>2 filaments) and the full colour Eufy stuff looks more interesting these days or something capable of 500c. So Iām going for the more closed source but far more smooth sailing and convenient bambu (prusaās OCL can fāk off), because at least theyāre honest about open-source (basically no), and Iām fed up of attempting to fix or improve a machine thatās great but tempremental, and poor at larger prints.
-Edit- The F350 must have felt this message through the ether, and proceeded to crank out a perfect calibration grid and proceeded perfectly on to a 26hour 600g 300x300x110 centrifugal fan wheel that it had succeeded near flawlessly about 60% of the time (ignoring when trying Arc fitting in orca - G2/G3 which broke the gcode but A350 supports with the correct args - wasting 3 rolls).
I changed the artisan Firmware for minor things like skipping the laser password 
Or to not be forced to calibrate after toolhead change.
Since that worked great, i will do some other stuff in future. Really cool to have AI for something like that.
I think we can safely assume that Snapmaker 2.0 spare parts will not be produced anymore, so when the stock is gone from Snapmaker warehouses, expect to be on your own.
Products that are also interchangeable with Artisan (Rotary Module, Dual extruder head, some lasers), Iād predict have spare parts until Artisan is decommissioned, which Iād assume will not happen in the near future. My guess would be that they keep Artisan in their portfolio as their 3-in-1-offering - there is a market for that.
With a bit of luck, they shoot out new modules for Artisan at some point, and if we are really lucky, they are compatible with Snapmaker 2 - Artisan & Snapmaker share a lot in their DNA. But I would not count on either of it.
Very much my opinion: I cannot share the criticism that Snapmaker did not deliver on their promise, adding capabilities to the SM2. Yes, there are more ideas out in the open, and yes, some problems of the machine were never addressed to full extent, but all in all the machine is usable and capable, and IMHO even rather versatile.
Currently U1 grabs their full attention, and I guess in their shoes Iād do the same: It is a vastly popular machine, acclaimed by the critics, many things done right, open source and embraced by the community - it would be stupid not to cater to that success. 3-in-1 suffers from that short-term, but if it makes Snapmaker a solid company to ride their current success (which may not stay that strong with competitors ramping up their toolchangers), at some point innovation will also come back to the 3-in-1 product family.
Software guy here: the whole open-source thing is a bit of a two-edged sword. Or would be, if Snapmaker actually followed through. The 2.0 was āopen-sourceā, and I mean those quotes. I donāt actually know what the status is for the U1, but speaking of the 2.0ā¦ Both Luban and the firmware are posted for modification but:
1 - the firmware is outdated. I have things Iād like to try doing there, but using the currently-posted source code would mean downgrading, since itās functionally on par with the 1.20 series. No vibration compensation, and no support for direct Orca connections.
2 - Luban is complete as a frontend, but incomplete as a backend. Critically, the code for toolpath generation (gcode for laser and CNC, in the LunarTPP tool) was never published. Iāve done a bunch of performance enhancement modifications to Luban, but Iām absolutely unable to fix laser-related issues that annoy me.
3 - Most importantly: open-source only matters if thereās enough traction around the product to build a healthy community. I havenāt seen an explosion of SnOrca forks, or firmware mods for the U1, or the 2.0, or the Artisan. I absolutely get that it matters to some people, and I honestly love being able to mess around with my stuff, but if people canāt/donāt provide value back to the ecosystem (either by creating parallel environments or by sending improvements back to SM), Snapmaker (or any vendor, really) has no incentive to bother spending resources on open-sourcing stuff.
I was asking, some time ago (before orca connection release) if the GitHub firmware has the vibration compensation feature and they told me yes it has.
Iām only a software wannabe so no real new coding on my side.
I ask for, letās see what we get.
It does, and I was wrong. I was looking at the wrong firmware releases.
M493 (FTMotion) was added in March 2024, and itās still there. The last update to the firmware source was December 2024, around the date V2.3.2 was posted to the forums (the M600 fix). So the only functionality missing is the Orca interface from 2.4.0
But what I really really want is to poke into LunarTPP and fix its annoying inability to convert a simple filled geometric shape (like a text characterās outline) into straight, lined-up lines for engraving, which makes text come out fuzzy. Even a simple SVG square will come out with lines of slightly different sizes.
Fear not, the orca slicer connection never worked for me in official firmware anyway.
This weekend I made all the online dependencies optional + timeout (so loads quickly on vpn / lan instead of infinite wait) and bundled it down so Win Defender loaded it quicker, and then strapped on an MCP server and Skill for CNC roughing, probing and tool setting, mostly concentrating on safety. Itās definitely not safe (like any CNC job/project), donāt leave unattended and have your hand near the power switch / emergency stop.
Once Iāve tweaked it a bit Iāll maybe offer it up somewhere other than a random fork in github, but even with human confirmation and 2FA, the risk to people who donāt follow instructions is almost too great.
and a much longer recording of it probing stock, missing and getting caught by the safeguarding (good!) and me giving some design feedback as well as approving jobs:
