I solved the problem

For some unknown reason when I set up my profile for the laptop in my shed, the "macro" folder was missing a lot of files.
When I compared the contents of the "MachTurn" macro folder with my "chrisjh_turn_shed" folder there were a lot of files missing.
I copied the contents of MachTurn macro folder into "chrisjh_turn_shed" folder and fixed the problem. One of the many missing files was M1083.m1s which is why the peck drill routine did not work.
I don't understand how this happened as I started off with "MachTurn" profile and saved it as the new profile.
I tested to see if G83.1 mode works as described in the manual. It behaves the same as G83. I presume that this is because there in no M1083.1.m1s macro.
