    I own a stepcraft but want to extend the y to 1000mm. I like the super heavy sphinx and the rover upgrades. the stepcraft is a cbeam with brass rollers against the aluminum. It seems not too strong. I've noticed debris run over by the rollers pits the cbeam. I wonder if a linear rail mounted to the c-beam would be stronger. it's steel for one thing. You would have bearing blocks instead of rollers. Also the stepcraft uses threaded brass for the lead screw bearings, no recirculating balls. I think this contributes to drag. I was wanting to put together 2 linear guides for the y axis complete, then incorporate them when they are ready. I would also change the x at the same time. Any help appreciated. Thanks Duane
