Now that I have the electronics working and my motors spinning, I am going to begin cutting parts for my JGRO this weekend. I have been studying the plans and putting the entire thing together in my head, but I am confused about two things. The first thing is with the edge holes on dtl16. The middle hole (for the dowel) is located 1.438 from the edge I believe that these holes should meet up with the holes on the Gantry Front piece (dtl20) however the spacing on these are different than the spacing for the uprights. The dowel hole is 1.375 from the bottom. Is the 1.438 just a misprint or am I looking at it incorrectly?
The second question I have is in regards to dtl18 Gantry Bottom. There are four threaded holes that are called out for Jack Screws. What are these used for? I don’t see anything attached to them in any of the assembly pictures. I am planning on incorporating anti-racking cables and these locations would work well for the wheels if they aren’t needed for anything else. Thanks for any clarifications you can give me.
