I'm just starting to make a set of motor mounts for my 7x10 based on the JFettig design. I have some motors and controllers kicking around so it will be a cheap project at least initially. My X-axis feedscrew has around .008" of backlash which seems impossible to adjust out so I suspect that will be my limiting factor. I'm more interested in automating tedious work than being able to turn perfect balls and arcs so I'm going to give the cheap-and-dirty approach a workout first. |
