I have a number of Gantry style woodcutting cnc routers in varying states of disrepair. I'm seeing some strange feed issues during interpolated Z movements and am starting to suspect it is an issue in the pressure of my balance cylinders. So my question is what is the best way to set those? Should the carriage be basically weightless with the drive mechanism detached?
