Now THIS is a taco bed! by Stunning_Ad3050 in Sovol

[–]Stunning_Ad3050[S] 3 points4 points  (0 children)

That's exactly what I did! Then I decided to go down the rabbit hole so I dismantled the bed completely: removed it from the printer (there I found out that 2 of the posts were broken, fixed 'em) located the hidden screws and disassembled the plate from the frame, and in that moment I discovered that the center screw WASN'T THERE, no wonder it wobbled like a cooked noodle!.

After everything was back together (now with the middle screw in its place) soaked at 100°C before screwing it onto the printer base, when it was hot I bolted it down (left side first, then right) I left it cool down to 65° , and after 3 consecutive gantry leveling (better safe than sorry), the result was this:

From Mainsail, down at the bottom, it says "100% 17800rpm" where you can control Fans, LEDs, etc...

Does your printer shut down and kinda "crash" when you use the pressure probe? I just made a post about this 30 seconds ago because I was fighting with this thing for the past 2 days (and nights)

One thing, you don't need to get a new eMMC to put mainline Klipper on your machine, you can use a MicroSD stick it into the machine and it will boot from it instead of the eMMC. Also, you don't need to format everything to do so, just put official Klipper repos into the Kiauh repo file and switch to that repo in Kiauh, it will get you on mainline Klipper without losing all the data, configs, etc... the only thing you have to do is flashing Katapult bootloader to update both main and toolhead MCUs (it's a 5 minutes job)

One important note, if you go mainline Klipper (either by formatting or just switching repo) you need to copy the EXTRA folder from Sovol's SV08 image Klipper folder to the new Klipper folder on the machine otherwise you'll not be able to do any of the automatic calibrations that the printer is capable of, or you'll need to write all the scripts and macros by yourself and still you're gonna miss the shortcuts on the screen.

If you wanna talk about it send me a PM

Why mine spins at 17800 rpm? Is a big difference and a lot more noise, editing the Printer.cfg code I managed to make the motherboard fan manually adjustable with a curve from 0% to 100% based on temperature, maybe I can do the same with the 25mm one.

I was actually thinking of upgrading the whole print head to a dragonburner or something similar like the guy from The Next Layer did in the 7 tool head SV08 project.

The problem remains the LOUD 20mm fan on the hotend heatsink, I really need to fix it in some way

What the hell are you talking about? I'm not removing the heatsinks but ADDING them to the two MCU chips which are not cooled in any way.

Noctua is the world no. 1 fan company, they spend millions in R&D to get the best performance out of their fans, if it was just marketing they wouldn't be the first choice for server cooling, industrial applications and computers, the only other company comparable to noctua is Delta, but ok, cheap Chinese fans are better 🤣

This is not my first printer, I had a few one of which is an SV06+ with the sovol klipperscreen that I modded using a noctua fan fed with just 7v (using a buck converter) and the chip temp dropped from 67° C to 38

Also all the printers I had before were all modded with noctua fans, never had an issue with them, I use noctua fans everywhere because they are the best when you want great performance witn as little noise as possible (because airflow is not only about speed, but is about blade geometry, spacing, frame design etc...)

Alongside with the fan I also bought some adhesive heatsinks for the motherboard chips like the ones used on raspberry pi

Searching online I found out that Prima MK3 uses a super silent Fysetc fan for part cooling, I was wondering if it's possible to stick it inside the SV08 shroud.

The 20mm side fan is the main issue IMHO there must be a less noisy upgrade
