I purchased my first 3d printer. It is a Tronxy X5SA Pro. I have heard a lot of negatives about it. Well I found out none of that is true. It went together extremely well. It is tight and square. I had problems with PLA not wanting to stick. I finally took off the aluminum plate to wash it. I discovered I had it on upside down. I turned it over and it printed with no problems at all. I am watching grandkids but will print something else in a little while. I am very happy with this printer.
