I beg your pardon. Please note that, no matter what the problem you have, please contact us first. A part of customers, who are starter of 3D printer, lodge complaints without any communication. It is temerarious and irrational. As is known to all, 3D print is a new field, we could not accomplish at one stroke. Before leaving our factory, each Board or kits of sets are tested to ensure top working performance. But the transportation is unexpected.
1: Power Supply (GND/VCC)
As is known to all, the old version ramps 1.4 is just compatible with 12V power supply, but now the new version ramps 2 in 1 board is compatible with 12V as well as 24V , we just need one channel power supply.
