G81 problem

[rob jerico]

i've been doing alot of different milling on my fadal i just got, so i tried to drill a hole, machine just ignores the G81, G83, ect, here is an example

X0.Y0.
G0 Z1.0
G98 G83 Z-1. R.1 F10. Q.1
X5.Y1.0
G80


am i just being stupid or what?

You dont have your P in there... P is the distance your drill stops before the next feed...I use P.02...alot in different materials because you can occasionally get a chip in the hole and you dont want to rapid into it.

[rob jerico]

can you give me an example

[cadman]

Actually, you don't have to have a P word in the line unless you want a feed before peck. A P word is optional in a peck cycle.

Unless this mornings coffee hasn't kicked in yet, I don't see anything wrong in your example unless there is problem somewhere in the program before the canned cycle. Can we see the entire program up to the G80?

[cadman]

This is a section of working Fadal code. You also don't have to have X & Y values in the line, but it is good practice because the cycle will start at the last co-ordinate before the canned cycle.

Cadman you should try giving him a basic sample without E's and other misc un-needed digits.

[cadman]

And what is wrong with that sample? There is no problem in rob's sample so chances are there is a problem before or after. Nothing wrong to see some other lines or addresses.

This is a long shot, but has some macro file been erased, something that might contain the logic for execution sequences of the drill cycles?

[cadman]

Another long shot - are you in dry run mode? and not that it would make a difference, but what format is the controller running in, 1 or 2 ? I only ran my Fadals in Format 2 so I don't know much about Format 1 but there are some minor differences.

[rob jerico]

well i used the example above and it worked, must be something i wrote before it, i'm not sure what format im in, how do i check that? thanks

[cadman]

I sold my Fadals over 2 years ago, so if I remember correctly, one way is press the space bar until you get to the Functions menu and Setup is the first choice on the menu. In the Setup page you can change or check parameters.

In the Command mode you can also type SETP & press Enter to access the setup menu.

Rob--
To get the program sample to work in Format 1 as you have stated it, go to SETP and change the IMM. FIXED CYCLE parameter to a YES. This will make the drill or tap cycle function when there is no axis movement on the drill or tap line. Format 2 defaults to this method.
