You need to move at least 30mm per second and preferably about 100mm per second of roughly 400 inches per minute. Mine can jog at 120mm/second. When a printer is working you really have trouble tracking the head with your eyes, it almost moves a little to fast to watch. Not only does moving this fast speed up the print but it allows the plastic to flow through the extruder at a better rate. You need a minimum speed for things like bridges where you print over air such as across the top of a hole in a wall But LinuxCNC would work fine as a controller. A printer is just like a 4-axis mill. But why? Printer controllers cost about $40 complete, stepper drivers and all and fit in your hand. The entre printer, extruder, controller and all is under $200. (they have a sale going now.) Seems a waste to spend weeks modifying a mill and milling software t make a machine that is not nearly as god as one you can buy for $189 -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
