That machine has 1204 trapezoidal lead screws with Delrin or bronze nuts so very inefficient. The stepper motors are probably 1.1 or 1.5Nm. I'd hazard a guess the Z-axis stepper is struggling with that additional weight. You either need to counterbalance it, or upgrade the stepper/driver combo or replace the leadscrew with a ballscrew.
As Jazz says, you're on a hiding to nothing....Last edited by irving2008; 11-01-2014 at 08:13 PM.
