Hi Robin
Thank you for your advice.
I'm going to start nosing around for belt drive applications, but if you could post drawing or pictures they would help me understand what you mean.
I've a bookmark for HPC, but haven't reviewed what the sell yet, will go and have a nose soon.
With regard to the weight, is it really that bad when compared to the weight of the gantry? I know rotational inertia is a problem for acceleration where large diameters and masses are involved, lighter flywheels on cars & bikes don't improve power, they effectively loose mass that needs accelerating, but then we are talking several lbs saved at 10s of inches diameter there, rather than ounces at a couple of inches. I think cost will be more of my consideration here rather than acceleration, though significant, real world improvements can always change my mind where cost is involved!
Cheers,
Geoff.
