If you are using the firmware from folger, with the stock config settings, and everything is built according to the manual, try moving the X axis stop sensor from the max pins, to the min pin on the ramps board. That's the next set to the left from what it says in the manual - the second pair from the right end. Thats what fixed it for me.by Bert3D - Prusa i3 and variants
Is Autodesk 123D really that bad? I've not tried it,but a friend uses it and recommended it. I've also played with TinkerCAD, and while limited, it is quick and easy to use for some basic things.by Bert3D - 3D Design tools
Ok, I have to ask. The pictures here show small carriers running on a track/rail attached to the extruded aluminum. The pictures in the folger 2020 Kossel on ebay, and at the Kossell site, show wheeled carriers running in the groves of the 2020 extrusions. The folger site says nylon slider wheels. Which actually comes with this printer? And which works better? Linear track, or wheeled truckby Bert3D - Delta Machines
