I do hope that this is the right place to beg a G-Code question - if not please advise, and maybe move to a more appropriate section.
I'm making a sacrificial table for my Denford into which I will be putting a grid of M4 threaded inserts.
This entails drilling a series of holes - all the same diameter and depth - so I've been reading the CNC Cookbook tutorial which tells me that the parameters needed for a G82 Drilling Cycle are :
- - X-Y : Co-ordinates
- - Z : Bottom of hole
- - R : Retract position
- - P : Dwell time
- - F : Cutting Feed Rate
- - L : Number of repeats
Now, I understand all of those but can't see where the distance between the holes is specified. I can see that the holes must be in a line - either on the X or Y axis and that a second/third (and so on) cycle would be needed to create a [grid] - in my case this will be 50 x 40 (X - Y)
The holes will be less than two diameters deep so there is no reason to use G83
I've read the tutorial a number of times but cannot see any reference to the spacing -- what am I missing?
