just got off the phone with legacy...very nice and informative conversation...here are some "fun" facts...big difference between the rack and pinion set up and having the steppers connected directly to the lead screws...if the steppers are connected directly to the X axis lead screw, for example, and you did a somewhat lengthy cut (e.g. 8 ft.), the time to come back to your starting point is considerable...so i might(maybe!,possibly!,will consider it!, etc.) look into setting up the racks and pinions as a custom mod...what is a bit frustrating, is the fact that the original purchaser of the 1800, purchased the cnc upgrade package($7,500, back in 2008) when they purchased the machine, but opted out of the rack and pinion option( UHHHHHHH!), which saved about $450...so thus the reason i do not have any racks and pinions...ok, so if i do want to go to R and P's, i'll have to dive into the MCM book...but i also found out that the stepper motor brackets were different as well...which means more mod work...so i might just set things up as originally intended, direct drives on all the lead screws(and a stepper on the headstock) and see how well i can adapt to the cnc world...then there is the overall cost factor(buying the machine, increasing mcmaster carr's profits(LOL),labor, etc.,etc.) as compared to just buying a new machine from legacy...but then i would be depriving mac the opportunity of critiquing my work, LOL!...well. stay tuned as this saga comes to the big screen!...thanks...joe
