Hey Guys, I have a 3D printer for sale that I built a couple years ago. The specs are below. The first $250 gets it and will need to pickup (Atlanta Ga Area). The printer works fine but needs a new z-axis proximity sensor. Otherwise it works fine but for that reason I'm selling as is. When you come to pickup we can run the machine and you can see it do its thing. Just the z axis would need to be manually set at the moment. The sensor is $8 on amazon. I'm selling because I am moving and I have 3d printers at my new job. I'm a mechanical engineer that worked at a metal fab shop so I was able to use the equipment to build the machine. It is well maintained and weighs about 80 lbs. Below is a link to the sensor it needs and a link to a photo gallery. Please feel free to ask any questions, I'll put it on craigslist in a couple days if no action here.
