Motors connected & scales calibrated today. I suspected I would have to slow it some, Z in particular once it had the mass of the gearing & screw to deal with. Poor half nut mount, lots of backlash there. To get real Z axis accuracy will likely take a ball screw though. X seems to work well though. Big band of rain about halfway across Indiana, so its likely going to be wet here tomorrow too, for an hour or so. > -- > > ------------------------------------------------------------------------ > ------ For Developers, A Lot Can Happen In A Second. > Boundary is the first to Know...and Tell You. > Monitor Your Applications in Ultra-Fine Resolution.
