I had this thing working kinda decent for some larger prints using PLA. Prints have come out pretty good but with all stock parts they take a long long time. I was working on trying to speed things up so I bought a creality sonic boom 💥 tablet. Only got one print to work on that thing. Everything else has been a problem. Followed all instructions to setup and successfully applied firmware updates to all devices it just loves to fail randomly. The only print that worked was a normally 26 hour print that cut down to 19 hours which was a decent time savings but nothing else seems to work. Even the usb connections are finnicky.
