Define bolt hole and Setup axis Position Grid Hole Pattern This function uses a defined grid hole pattern to set X and Y axis incremental zeros at each grid hole position in the pattern Hole 1 of the grid hole pattern is defined as the incremental zero of the X and Y axes when the function is started The relative position of the holes and the angle of the array are a function of the how you choose to set up your axes If you choose to set up both X and Y axes with invert no then you will e C see hole 1 in the front left position with the angle set to zero 3 4 When an angle is set the array will CES 5 pena 4p rotate about hole 1 and go 0 0 1 2 counterclockwise when a positive angle Is set Page 28 of 41 November 25 2009 The Unofficial User s Guide to the Shumatech DRO 550 Version 2 0 If you choose to set up your X axis with invert no and your Y axis with invert yes then you will see hole 1 in the back left position with the angle set to zero O T o 3 4 When an angle is set the array will rotate about hole 1 and go clockwise E when a positive angle is set cd A 3 If you choose to set up your X axis with y NEWS 5 invert yes and your Y axis with invert no then you will see hole 1 in the front right position with the angle eig o 2 E set to zero POE i c When an angle is set the array will rotate about hole

5. DRO 550 Version 2 0 Overview of the Document s Structure There are three layers of information available in this user s guide The top layer is intended for users familiar with Nu the functions who just need a little memory jogger in order to get to the right menu page This layer consists of a series of reminder cards and are very cryptic Two formats are offered See page 7 The middle layer presents each function with enough detail to fully use it See page Error Reference source not found The bottom layer explains in detail why you would want to use each function Sometimes the value of a function 1s only clear when you learn how it 1s intended to be used This layer is in a companion document because not all users will want it Application Notes for the mill configuration is now available Common functions in the context of the mill are also presented Application Notes for the lathe configuration has not been written yet Cutting vertically through these three layers we have functions that are only available when the DRO 1s used on a mill A second set are intended only for the lathe Then there are functions that are common to both mill and lathe The idea here is that each description is only given once The DRO 550 has 3 large displays You may see for example Function position tool offset Within the text part of this document you would see this represented by Position tool offset As you set up
