this is an follow up to my original post https://www.reddit.com/r/SovolSV08/comments/1t4pl3r/how_screwed_am_i/

I replaced the toolhead but the printer still stuck on the system loading screen. I cannot reach the mainsail and when I try and ping the ip on terminal, the host cannot be found.

When I take off the bottom covers there are solid blue led lights on, no red. I tried unplugging the toolhead umbilical, still nothing.

Is the next step to try and reflash the emmc? Do I need to get a new main board?

Thank you again for all your help.

Hey Redditors,

Let me first off start by saying what an amazing resource this has been and how helpful posts here on reddit have been.

So I am new to the 3d printing world and although I read that the sv08 requires tinkering I thought I would be able to manage as I am fairly mechanically savy but with not a lot of 3d printing or electronics experience.

I was changing the nozzle on the sv08 today and was following along with the sovol youtube video. It turns out that in the video they dont actually show you how to change the nozzle, which is frustrating.

What I did was try and change the nozzle with the sv08 on and I created a short on the board of the toolhead when I was removing the two allen bolts. It occurred on the left side of the toolhead where there are the 5 soldered points. I saw a spark and a red light came on below the toolhead. Now the startup screen is stuck on "system loading."

I use gemini a lot to try and help me learn and reached out to customer service but I havent had any luck so far.

How screwed am I? Did I fry the MCU on the toolhead and need a new one? Is it an easy fix? Thanks for your help
