Hi lcifers --
Thanks for posting this.
It sounds like you are making good progress with your 1624 and I am interested following your diary.
I am in the process of getting familiar with my new 1216, and figuring out what remains to be configured in Mach-3. We all are "reinventing the wheel", since there are no "hints" in the Zenbot set-up instructions for setting up table size, home, soft-limits, offsets and etc. There should be a "best practice" to help a person get off to a quicker start. Maybe your thread will help document your discoveries and perhaps contribute ideas toward a quick start guide/reference. xcayba (and others who have responded here) may also have some valuable suggestions.
Eventually, I'd like to find an official or unofficial Zenbot specific forum, ...perhaps on Yahoo or Google groups if not as a sub-forum here in CNCZone. What are your thoughts about that?
