I bought and assembled a Kossel mini kit that was pre-flashed with the firmware. It was able to communicate with pronterface via the USB however, when I plugged in the mains in order to control the steppers for calibration Pronterface stopped responding. Then the LCD went black and I couldn't get power back. The USB wire was hot to the touch. I then disassembled and flashed the firmware in case something was wrong with it and I managed to get the printer working again without any stepper drivers. it turns out my E0 stepper driver connectors were frying every stepper driver I put in to it and shutting the lcd off. The seller suggested that it would be the arduino that is the problem with a faulty 5 volt regulator and after they wanted me to check this by repeating mains and USB together it fried the arduino so they offered me a replacement at discount dismissing my concerns that the ramps board was killing every stepper that went on E0. I have re-wired the printer without the stepper drivers or stepper motors connected and flashed the firmware onto the arduino.
The same thing happened, worked mains only, connected to pronterface fine on USB only, but when both are powered it fails to connect I Quickly checked the USB wire and it was hot so I immediately disconnected it. Is the seller right in saying the ramps is fine? They checked all my wiring and I am certain it is correct.
Any help will be appreciated. Thanks.
