My ATX is a Kraun with 12v1 8A and 12v2 12A, is connected to a Prusa i3 with ramps 1.4.
Yesterday when i start printing the calibration cube for the first time the PSU shut down.
This happend also if i set 230° C on the extruder and 110° C on the heated bed.
I thought it was because there was only one wire per hole in the ramps, so now i have put two wires in the 11A hole (two in the positive two in the negative) but when i move the axis pronterface says:
Can't write to printer (disconnected?) (SerialException): Write timeout
Can't write to printer (disconnected?) (SerialException): Write timeout
Can't write to printer (disconnected?) (SerialException): Write timeout
Can't write to printer (disconnected?) (SerialException): Write timeout
Disconnecting after 4 failed writes.
Disconnected.
Connecting...
Could not connect to COM6 at baudrate 115200:
Serial error: could not open port COM6: [Error 2]
and the printer disconnect from the pc,if i pull out again the usb cable and then plug in, the printer connect again.
Do you have any suggestions?
Thank you
