Problem to start printing
Hi, I have a 3d printer that works with arduino Mega and ramps 1.4. The arduino is connected by USB to a Raspberry PI. The raspberry has repetier server installed. The problem is when I put some file to print, the printer make homming in all axes, turns on the heatbed and the hotend, but when it reaches the temperature, It does not start to print. I don't know why that appends. It was working well. Arduino mega has Marlin firmware. I check that the buffers were the same that the repetier Server. I try with repetier Server 0.70 and 0.75b. I also change my raspberry PI B for a raspberry PI 3. I thought the problem was that the heatbed is too slow, but when I try with a lower temperature for PLA, I doesn't work too.
What can it be?
