Hey all, I decided out of curiosity to open up the touchscreen on my SV07, and found some very interesting bits inside. I’ll attach pictures to this thread of the internal board, and close-ups of some of the interesting bits.
First, the board inside is labeled as the Makerbase MKS KLIPAD50 v1.1. I haven’t been able to find much regarding this board online, it’s not listed anywhere on Makerbase’s website, store, or github. What I did find of interest is that the storage for the device is a EMMC/NAND flash chip (specifically the Samsung KLM8G1GETF, datasheet for the curious: KLM8G1GETF-B041 pdf, KLM8G1GETF-B041 Description, KLM8G1GETF-B041 Datasheet, KLM8G1GETF-B041 view ::: ALLDATASHEET ::: ) using a special connector. On their AliExpress store (https://www.aliexpress.us/item/3256805428404625.html), they appear to have a USB adapter for this connector, meaning it should be possible for someone to pull the data off the chip from a new/unmodified machine and upload somewhere as a “fresh” copy of the software on this machine.
I also found a USB-C port that the case doesn’t reveal, labeled “Download”. I’m not sure what the specific purpose of this port is, or why it’s not revealed by the case, maybe a diagnostic or software upload port that’s not used after manufacture.
If anyone has any information on either of these points, or anything else, feel free to post here.
Very interesting. Where does the antenna wire lead to? I have really crappy wifi connection with mine…
Antenna goes to a small strip of metal on the case, but there’s no reason you couldn’t get a better wifi antenna and hook it up. I saw someone got one of the sort you find on the back of a desktop wifi card or a router, and got it mounted at the top of the case
I just went through the Klipper/Armbian update using the 9/13 update from the Sovol downloads on my 07 Plus. Everything “appeared” to go as shown in the upgrade video, but upon reboot I’m bricked.
Thanks for the link to that EMMC module adapter. I’ve reported it, but I’ve no idea how long it will take for the Sovol team to get back to me. I’ve been hacking Linux since 1993 and figure I can get things sorted more quickly with my own efforts.
Love the keep-alive circuit to perform the proper shutdown when you power off.
I’m not sure how badly you’re bricked, but it’s not the first I’ve heard of the printer being bricked after applying that update. I did find a couple github repos for people with bricked machines, one includes instructions for a USB connection that gets you to a terminal on the MKS board, so you might be able to use that to restore connection to wifi and fix the klipperscreen software that runs the touch screen. Here are the links:
It’s never getting to the kernel load from what I can tell. The Blue LED never comes on and the display stays completely dark.
