Love the printer super quiet and easy to use. Nothing was wrong with the old board until I started to do some upgrades to print TPU. Used a of brand Stepper Motor and forgot to flip the wires and fried my board. All good now ordered a new board and Stepper Motor from LONGER and Im printing TPU now no problem.
Works great better than the creality model cr10
I'm going to be using Longer product for a every long time i had to replace my motherboard on my Longer LK1 3D printer no one had it so i went to the source i ordered it and in about 10/12 days it was on my front porch easy to install plug and play very easy i will post a video soon
