Z axis jog moves spindle only incrementally

Thank again for the help and it now appears to be working and will run programs. I did use the configuration that RIck last sent me.

In answer to RIck's last question, I had read the section on Homing Sequence and will readily admit that I could never completely digest all the options and their interactions. Like it approximately says in the Sherlock Holmes stories, it seems simple once it is explained, but I could never fully explain it to myself and still am not confident that I could make anything work.

Thanks again to all.

Glad you got it sorted out!

Homing has confused many others in the past, but seems simpler once you have it working.

Thanks for all the help in the past. At this point, I have made progress with all the help.

But now need assistance in an area that I am not certain whether I should even ask for help as possibly there is a coding problem.
I am attaching two programs that I have written and will run on my machine, but in the first one (firstone.ngc_ the Z axis goes down towards the XY plane when the Z axis runs a positive number. However, when I run the second one (tabledrill.ngc) I would swear that the drill cycle is upward.

Excuse me if I am asking this question in the wrong forum.

It looks like t he attached files did not make it so I will try again.

First I wonder if you've made a machine config blunder. Normally machines are configured such that Z- moves the spindle down towards the work piece and Z+ moves it up. So if you've configured your machine so that Z- moves up, a canned drilling cycle like G81 would drill up instead of down.

Thank you very much for your reply.
Originally, I had the Z axis configured to go positive down and then concluded that the canned cycles would not accept that so I changed it around so it was negative down and still could not get the canned cycles to work properly.
What you have confirmed is that I do not know how to properly program canned cycles.
So I will convert it back to negative down and try some more to get it to work.
