I'm currently running 60ipm rapids, with no problem. I've tried the max allowable (which is limited by the 25,000Hz MACH3 setting for the PC's parallel port) of 118IPM, and it seems to work, but I plan to thoroughly test it (where testing involves zeroing, then rapiding the table everywhere for a few minutes, then checking zero again).
Your column flex is much more a function of acceleration rather that IPM. Once I had the accel set to near-infinite, and Z starts and stops would shake the floor. |
