New F-linear modules

Hi,

Where did you see the extra 10%

It was announced in the presentation yesterday. 10% discount for backers, no expiration date, stackable (!).

Wow, that’s cool and a nice gesture to their core/funding community!

750 dollars is a lot of money. they are shown on the web site already and can be ordered without discounts.

i am on the fence about it still. no expiration on both offers?

I’ve been talking with Snapmaker, and they are saying that there isn’t any special discount for backers. They said that the 10% discount is only for those who purchased both the Snapmaker Original and a Snapmaker 2.0 at the same time.

heh, tell me about it. For what the A350 costs, I got a fully-tooled '55 Bridgeport a couple years back. Most of what the A350 produces gets chucked straight in the garbage bin - at least when the bridgie produces scrap, I can reuse it for other parts :wink:

I haven’t seen anything about the new modules that makes me want to upgrade. Quieter would be nice, but I can get that with more soundproofing panels. The new 3D print head is the one that shipped with my A350, so nothing new there. Maybe this is why SM never sent me a coupon for the discount

@edf theyre also 50% faster

Yeah, I saw that. Doesn’t really help me; I have to slow most of my prints way down as it is, and I’ve stopped switching the SM to laser or CNC mode because it just takes too much time.

i run on the slow side when i print. maybe the speed increase means with quality, maybe it doesnt. haha.

@MooseJuice I run the slow side too, but it would be nice to have the Snapmaker print as fast as my others though, especially since the A350 is larger.

i mean i can print faster than i do now but that doesnt come out good. are they going to come out better because of something different about the modules or are they just technically faster i guess is the question.

I’ve been using Spidermaker Matte as my go-to filament for awhile now (partly, I admit, because the A350 is dialed in for it and I’m a bit wary of screwing that up after all the time it took to get there), and it likes slow print speeds, on the order of 12-25 mm/sec. I can print it at 125 but it leaves a rough finish with very visible layers. I don’t think a faster module would fix that, no matter how they optimized it; seems to need some time to melt into the previous layer.

@edf i have a lot of printers, if what you said were true it would be the same for those too but it’s not. All of my printers are direct drive extruders as well.

Do you use the quick release model for the SM2 from Thingiverse? Makes changing the head wayyyy quicker - though all the screws for the beds are still a pain in the rear but at least they are easier to get at.

On those of you who print slow: Did you “upgrade” your module for better print cooling? E.g. by adding an external fan or using the new printing module? For those filaments that can be cooled without negative side effects (e.g. PLA) this allows for much higher printing speeds and usually even gives better results. The original printing module was very bad at print cooling if unmodified. For reference: I typically print at 60 mm/s on the SM2 (with added fan) and have no issues, and on my old CoreXY-printer I ventured up to 120 mm/s, which however caused some ringing visible in the print, so more typically I’d run 100 mm/s.
Especially with the huge build volume of A350 faster printing speeds are desirable…

Just watched the video @TheBlackfish linked in, and indeed it is very clear: Only the 733 backers that backed both SM Original and SM 2 get this 10%. Lucky them :slight_smile:

Too bad :frowning: Would have been nice with the 50% on the new items …

The head is easy, the bed is the troublesome bit - plus the downtime for the manual calibration of the 3D printer setup, the test prints to ensure everything is reasonably level, and so forth. I already have a ton of projects to get through that are entirely unrelated to 3-D printing, so the SM2 gathers a lot of dust because if I have to spend hours fiddling with the thing to get it to produce a part, it gets bumped down on the priority list.

Regarding the fan: yep, did the mod, took it off. I have to turn off cooling for this particular filament, so I doubt that adding more cooling would make it print better when run faster. But maybe it will, who knows? It works now so it’s going to stay in this setup until I’m snowed in and too tired to put in time in the wood shop.

The SM2 is my first and only 3D printer. It hasn’t inspired me to try others. Not really sure what the argument is there - the filament likes slow printing on the SM2, but might not require this on other printers, therefore the new linear modules are worth the money?

Do the new modules change the “magic number” of 0.04mm for the layer height?

The z-axis lead hasn’t changed - only x & y.
So no.
