Continuing to progress.
I tacked the 611 mount on to see how it’s range of motion compared to stock.
Both Z’s are at their lowest point. My preference would be to match the stock -Z without having to drop the 611 all the way down in its mount. Is there an engineering consideration that would prevent dropping the 611 mount plate on the new Z another 30-40 mm?
BTW, the hole pattern on the rails I received is 30 mm from the end then 60mm between hole centers, 5 holes total.
