# Thread: Two OM-s, different behaviour [UPDATED]

1. ## Two OM-s, different behaviour [UPDATED]

I have two machines both with Fanuc OM, only visual difference is that one has soft keys and another doesn't have.

1.
On one machine if I put R after G1, it will make radius between two G1-s (two lines).
And second machine doesn't do that radius, just sharp corner between two lines.

I can't remember other differences right now, but will post it later.

2. There is a parameter setting that allows a choice between using "R" or using "I, J (K)"

3. I just stumbled across a thread on this today. Check this out http://www.cnczone.com/forums/archiv...p/t-23343.html
Maybe it will help.

At my older machine, for G2 and G3 I can use both R and I,J,K, and for G1 (linear) I can use R to make radius between two G1-s.

Probably that should be some parameter....?

5. NEW PROBLEM:

One machine does subtract tool length for abs/rel coordinates if G43 H_ is activated, and another does not.
Could that be changed through some parameter?

I like when coordinates are shown with tool length compensation.

2nd PROBLEM:

When in offset screen (tool length register), one machine shows me abs coordinates and another shows relative (silly to me).

Of course I appreciate absolute coordinates, I am used on it.

Any parameter for that?

6. for your first new problem try parameter 18 bit 5 (6th from the right). But i cannot help you for the 2nd problem

7. Your second new problem is controled by Par# 0028, bit 0 (the first one on the right side)

Thank you, that problem is solved!!!

In my yellow OM book that parameter stands for :"On the program check screen, the absolute coordinates are disllayed."

And it is set to 1.

I need to change abs/rel in offset (tool length register) display
