I just put my Sovol SV01 together. I went ahead and bought the bl touch adapter mainly for the experience of working with one. I kinda sorta got it to print once but now it seems to be way too far above the build plate. I would love to see a better firmware for the printer (I used their 1.1.6 firmware intended for the Sovol SV01 but unified firmware may be better). Would it support the bl touch? There's not much information on all of this out there as it is not one of the more main printers out there.
Glad to hear you're working on it and hope to hear more on it. I really do need to get around to printing some mounts and installing that EZABL I bought so long ago on one of my other printers. 🙂
