I upgraded from 2872 early this morning after a couple hours run. Started Mach and had troubles with homing, backing off the limit switch. (I'm using ESS, +- and home one switch). Axis override wouldn't work so I had to take the L bracket off to disable the switch, which is the easiest way. These problems seem to have been fixed since 2803. All previous versions it would happen now and again. I know the homing is controlled by the ESS, but I had no problems with 2872. Went back to 2872, no more problems. I'm not looking for help, just a warning to others.
