I'd agree, but those of us using the D525MW need a 5i25 that will fit that teeny little slot on that board. It has crossed my mind to do that at least once in the last year, but that is the show stopper. Its something that I would need to get to a RELIABLE 20 ipm on the z drive of my lathe. I think I can get to about 35ipm IF I had enough psu to hold the voltage up while the driver was set wide open (4.2 amps, a bit under the motors needs for full jerk wired parallel) & the 8 wire motor was wired parallel. My x motor is wired that way now, but needs more psu and psu cooling to do that to Z. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
