You are correct that the material DRO is the same as the X center. There was another duplicate that I had fixed. Im traveling now, I will correct this and release a new version when I get home next week. Sorry for the confusion and not checking your first report closer.
The wizards should always remember their last value used. These values are stored in the file Newfangled.set.def in The Addons\Newfangled folder. Check to see that this file is not set to read-only. If you copied the wizard from a CD it might have been set read-only
I agree, if the RPM reading good and steady you ought to have a good trigger.
What Mach version are you using? Par port or SS?. There have recently been a LOT of work and changes made to the driver code for threading- see mostly the Yahoo group for lots of detail. If you are runing anythng less than the latest version you are wasting your time.
Ok, it looks like a G540 driver, and thats a very good device. Also a smoothstepper.
You only have 3 switches wired, the Negative in each direction. They are the home position.
You have Z home on Pin 10. Y home on Pin 11 and X home on Pin12
Use the Ports and pins setting and make sure these are the port numbers entered. Also make sure each is set for Active Low- that means the switch is indicating its condition when it is Low or grounded. Be sure you are set for port 1
The manual you need is the Mach install Manual, see the downloads tab at the top of this page.
