Post ramps 1.4 power connector melting
on: January 11, 2017, 09:58

Just installed a new ramps 1.4 from the osoyoo kit on amazon. Already uploaded marlin 1.1 rc8. lcd, endstops, motors everything works fine until I turn on the heated bed. When I turn on the bed the plug jumps to about 300 degrees and starts to melt the plastic. The bed does heat up but I stop the ramps before it fully melts.

Green power connector on ramps is melting.
I made sure to test all connections to the plug and re connected them to ensure they were fully connected.
