Ok, so I’m not to happy at the moment. Recently installed smart box and cr touch to my Ender 3V2. Since that day my printer has been a pain in the but. Random errors. On screen says nozzle temp to low. Done this while warming up for a print and 2 hours into a print. Only way to clear it is turn the printer off. Just now I’ve had to unplug the machine and smart box to sort it because it froze and the screen wouldn’t work. Also the slicer in this app is a waste of time. You cannot auto bed level for each print off the in app slicer. So at this moment I’m not impressed with any of the Creality products or services. But hay I’m $100’s in now so I’m stuck and I guess I’ll just have to suffer with crap system programming until someone can be bothered to fix it. What a joke. Would not recommend
