Hey Everyone
Was hoping to get some feedback on an issue i am having
Recently put together a RepRap and did a few decent prints.
out of nowhere I had an issue with the MOSFET that caused it to turn on every time i gave power to the 11A power rail.
I have since replaced the MOSFET with a new one (IRLB8743) and it functions as expected with 1 minor flaw.
Every time I give power to D8 while the heatbed is connected I get a disconnect message from pronterface.
The weird thing is, when i unplug the heatbed from D8 and set the bed temp the light on the ramps board goes on and it does not disconnect.
I am thinking there is some kind of short on the heatbed, but i have thoroughly inspected it and there doesnt seem to be anything that looks suspect.
I am using an MK2a Heatbed and have not had issues with it in the past - only since i replaced the MOSFET.
any help would be much appreciated.
Regards,
Steve
