when i turned on the big box for the first time, the LCD did not work and the beeper was going off constanly, I then turn the connectors 180 arround and then the LCD workerd, except for the knob. The knob itself cannot move freely unless I make the hole in the front panel allot bigger. after doing so the knob still does not work None of the temperature readings are working, wiring has been triple checked. And there is a permanent error MAXTEMP on the LCD I am unable to connect via usb to the machine control panel in simplify 3D Any ideas what might be wrong ?? also i have to say, on both the rumba and the LCD, the majority of the components were poorly aligned before soldering. i am pretty disappointed with the quality of the electronics
Strange thing to find flaw in. If it works, use it. Take it up with Geetech, that's where they bought the Rumbas
