Hi, I'm at finish building my first printer (prusa i2)
The last problem i have and i have no idea how to tackle is heatbed.
Connected to D8 at ramps 1.4 it heats extreamly slow, or none at all (after 5 min waiting it's still cold, you can touch it with fingers, after 10 minutes it get just little bit warmish)
Trying to locate the problem i temporarely switched it with hot end.
Now hot end gets cold and heat bed heats up fine, after 30 secodns the glass surface is preatty warm.
Is this the problem of Marlin firmware?
I am testing on prntrun.
Here are some pictures:
