lamicron let us know what you come up with. Your motor should have no problems turning that heavy beast of a gantry.
Post your calculations with explanations and we can check them for you. Sketches help too. For instance draw your whole x axis setup with the motor, gear reducer, shafts, rack and pinion whatever, showing all diameters, weights, acceleration, velocities etc and get one of us to calculate it. If something is missingf from the equation somoene will speak up and say oh we need to know whatever. This will help boost your confidence as you go along and build your machine. Its a great way to catch mistakes and gather opinions. I mean look at the mistake I made by using final velocity instead of average velocity.
I wish I posted up all my calculations on cnczone and had the guys here to criticize the hell outta them before I spent all that money on pulleys, belts, gearboxes, motors etc. It all worked out at the end so whew i guess. My machine moves 5 times faster than it needs to and i can even hold onto my gantry and go for a ride.
