Topic: Beware of Geeetech boards
I purchased a printrboard copy from Geeetech a while back to use as a backup in case my Solidoodle motherboard fried. Well, that day finally came and I was happy I had the backup board from Geeetech. It took me several hours to figure out how to load the firmware correctly, but I finally did and I turned everything on.
Initially, the motors all worked fine and everything seemed to be great.
Then I turned on the power to the hot end and heat bed. Within seconds, the leads going from the power to the MOSFETs burned out. After doing some research, it turns out I had an early version of the board that was designed incorrectly where the leads were not made to handle the current required for 3D printers. There are numerous other posts of people who had the same problem. They even admit on their website that the newer version of the board solves the issues that the early version had.
I emailed back and forth with Geeetech for weeks (not kidding). They refused to acknowledge that I had a faulty board, but eventually agreed to sell me a board for a discount off of MSRP. However, they waited until two days after raising their price to make that offer!
I have had a very bad experience with Geeetech and I would not buy anything from them again. They care nothing for customer service. I know the price is steep, but just buy the board from Solidoodle. It's not worth your time.
