My guess is that you edited the default setup files for your local configuration, instead of making a copy in your user directory. When the EMC updates were installed, it loaded a new default config file on top of your edited one.
If that isn't the problem, then there may have been some change in the handling of ini file parameters that has made one of your settings no longer make a setting. You mention the pulse width being very short, so you might check for that. I took a quick look at the configs/stepper directory, and didn't see ANYTHING about pulse width in stepper_inch.ini or xylotex_pinout.hal Maybe these files allow EMC to take the default, there must be some way to set the pulse width when using motmod.
