@MooseJuice agree about tons of other problems and they keep annoying me as well. it would be great if the company just offers some way to track all known major issues with progress in one place, what fixes we should expect in the next firmware update, etc. Clearly a better option than having angry customers venting about the same issues over and over again on this and other forums, spending customer support time, etc.
I can find some things had been mentioned in the firmware github, but there is not much about the hardware and not so many progress updates.
Snapmaker was really good at giving progress updates during the kickstarter period, this was one of the reasons i bought the printer, but now the communication style is a bit disappointing.
Thanks so much.
Just a little question. Where do you connect the 2 USB ports? Headed for power?
Could connecting 2 or more accessories to the power supply cause problems?
I mean the power supply is not that powerful and adding 2 USBs can overload the power supply. I read in the forum that the PSU is 320W and the printer consumes 290W.
That is a good point, Iām using it for a wbcam that I wanted to turn on and off with the printer. I havenāt had any problems, but it doesnāt hurt to be careful. The fusion file is there, you can always remove the USB holes if you donāt need them.
I have bought a noctua fan and a LM2596. ( used this Snapmaker 2.0 power supply fan 40x20 upgrade by AliSanjabi - Thingiverse)
I have connected the fan to the LM2596 and after to the PSU (See photo) but from the PSU there is no output to 24v. Tested via tester and via noctua fan that doesenāt spin.
Hi All, I got A350 yesterday and after power on the fan noise was bothering me. The design the way they packaged and used parts was really nice. I will give credit for 100 but the power supply noise for some reason the designer more focused on cosmetic lighting instead of better air flow. After taking it in part I noticed under the front cover there is while plastic for leds. This thing is blocking almost 90% of air coming in. So what I did is I removed the front white plastic including led strip and disconnected the fan in the back. so far so good. Internal power supply has itās own fan already but pointing up side. So the air will touch the top before moves sides. I will let you guys know if I ended up with any issue. another thing came in my mind is to use voltage regulator and drop the voltage for back fan incase we want to use it. I am EE I will help snapmaker engineers to improve the design. I like this company.
I wouldnt wana do any permanent change to it in the event something goes bad that will be their excuse for it failing. if i mod it, it needs to be reversible.
@JonathanSwivel does your fan blow the air into the power supply, or does it suck it out the air?
Standard fan on the power supply does suck it out, and the internal fan is placed in that same direction, to create an airflow through the power supply.
Hello @bastiaanslee ,
yes, as it is a radial fan, it blows air INTO the PSU unit.
I am aware that this is the opposite direction the original fan did it.
From how the PSU is bult internally iĀ“ve judged that it should do the job anyway:
the original ultra loud 35mm and also my 5015 replacement have the job to create air flow in the outer housing.
the smaller fan built into the actual PSU (lets call it inner housing) has the job to take some of that air and flow it over the critical components.
So from that reasoning it think that any fan, which creates air flow in the outer housing does the job OK.
So far, at room temperature, as I have the PSU outside of my printer enclosure, I did not experience any issues.
But as always, its DIY and no guarantees for a particular purporse.
Just wondering did this work with you?
As I understand its a direct fan exchange with no need for a convertor or a new back, correct? Did you need to drill new holes in the back?
Thank you!
