I have the same problem. I purchased a new board from Folger, after a few prints, I turned on the printer at the power supply switch and i luckily had the back of the printer facing me. the resistor(???) at L02 just popped with some flame and smoke. The board was already being powered by it's connection to my laptop through the usb cable. Now no connection with the laptop is possible. Here is a closeup of the burned out area of the MKS Gen 1.4 board. This is the second board to do this. the first was the one that came with the kit, the second was a replacement i just purchased from folger.
Every single part on here is the stock part that came with the kit.
Well that is a lie, i did print the modded adjusted tilt screen holder and moved it to the back after the first board burned up.
Here is the pic. Any help would be greatly appreciated. I am on the west coast and ordering a new board takes about a week due to the distance from NH to us.
Hmmm. Not sure how to include a pic. any help on that would be appreciated as well.
I can host the image on my secure website. will include that link below
That seems to work for me. If there is a better way of including pics i will be happy to do that process as well.
