GANTRY & DRIVE SYSTEMTracker's 3 axis gantry uses four 240 watt drive motors. One on the x-axis, one on the z-axis, and two on the heavier y-axis. You will find other systems use only one motor to power the y-axis with power being transferred to both sides using a jack shaft, belts, and other components. Imagine how many times the gantry changes direction every hour and put that stress on a small rubber belt and one motor. The belts will fail often, leaving you to order parts and repair your system. Aside from being complex and unreliable, a single motor also leaves the heavier y-axis underpowered causing lost steps and misalignment. Tracker's motors transfer power through a directly driven rack & pinion gear set. Direct drive eliminates the need for pulleys, rubber belts, gearbox's, and jack shafts and is far more reliable. Down time is frustrating and costs you money. Rest assured that with Tracker you will be turning out profits, not turning wrench's. |
