​I brought the printer with me to my summer place, and we had a massive storm yesterday. Lightning must have hit a transformer or the power lines nearby because the voltage surge actually tripped the dedicated circuit breaker for the printer's outlet. The printer was powered on at the time, but it was just sitting idle and not printing anything.

​When I went to the workshop this morning and turned it on, it got stuck on the "System Starting" screen for about 4 or 5 minutes. It eventually booted up, but immediately threw a Klipper connection error. After troubleshooting for a while, I flipped the printer over and found that the FAN3 port, which I was using to hook up an external filter fan, had completely melted and burnt out.

​I grabbed my multimeter to check things out and realized the 5V power rail is sagging down to 1.75–2.00V. Because of that, the DL7 status LED on the board is just barely glowing and flickering erratically—it's simply not getting enough voltage. Strangely enough, when I accidentally shorted that FAN3 pin with the multimeter probe again while testing, the LED suddenly lit up bright and steady for a split second. Everything else on the board looks physically fine aside from the burnt fan port, but there's clearly a major issue on the power side.

​So, I wanted to ask those of you who have experience with this:

​Is it even worth trying to fix this board (like replacing the voltage regulator), or did the surge likely kill the STM32H7 MCU for good?

​If the board is toast and needs to be replaced, what's the best option to get for the SV08 Max so it plays nicely with Klipper without a massive headache over pinouts?

​I'd really appreciate any helpful tips or advice!

The thing is, I could buy and install a new screen and connect it to the printer via HDMI and USB, but if I did that, I’d effectively have to throw away the original screen, and I don’t want to do that. So, if anyone knows how to install a Klipper screen on the Sovol SV08 Max, please help. Also—if it matters—I’m currently running the stock firmware, but I’ll be switching it over to Demon Klipper this week.

Guys, I can't make up my mind—please help. I want to buy a new 3D printer with a tool-changing system (a minimum of 6 tools is a must) and a print area of ​​300x300 mm (though smaller is acceptable). I already own a Sovol SV08 Max and an Ender 3 (though I’m constantly modifying the latter, so let's not count it). This has raised a few questions for me: 1. Which tool-changing printer should I choose? 2. Is the cost justified? 3. Or should I go for a custom build—like a Voron 2.4—and modify it for tool changing? 4. What are your thoughts on this?

To give you a better idea of ​​the situation: I am an engineering student at an aviation institute—currently pursuing a master's degree—who loves modifying and upgrading machine tools and creating something new. I look forward to your comments and ideas.

guys who have Ender 3 NG, would you like me to make a module for the printer that allows you to make a Toolchanger out of it (for those who don't know, this is a system for changing printer heads right during baking) that I can print 4-5 materials (it depends on how many heads I can fit into the case)

Regardless of the activity on this or my other posts, I will continue working on this project, and perhaps in the future, I will release it to the public. However, active interest in the project could speed up its release.
