XYYZ Gantry

XYYZ GANTRY

Good morning,

Asking for opinions on XYYZ gantry. I believe this
configuration will involve having 2 lead/ballscrew and
2 stepper motors for the Y axis. Suppose one of the
stepper on the y axis lose step. Does this mean that
the x and y axis will no longer be perpendicular to
each other? With this arrangement how does one ensure
squareness?

Thanks


Peter
