been over thinking again lol but that's the fun of reading tons of posts on this forum and coming up with new idea's (stolen idea's). just out of interest whats the price difference between good stepper motors and servo motors now? because of my high z axis i need to make the gantry very beefy but after reading some more for 3d work the z front plate needs to be light so i will update soon on an updated version and see what you think.
