Gantry style as I use the term describes a machine that has 2 Y rails carrying an X rail. All rails are independently powered so each has a motor/drive and all of the rails are supported above the work area. There are several 3d printers that use this configuration but not all of them are necessarily the exact design I would use. Here is a couple videos of one I made using "PBC Linear SIMO stages" it uses 10 start, 25mm/turn leadscrews so it is a bit louder than normal printers. https://youtu.be/fQ9PoQIl7q4 https://youtu.be/fQ9PoQIl7q4 https://youtu.be/zG-eEfDkFBo https://youtu.be/zG-eEfDkFBo
