Changing retract to safe plane in post.

[weber63]

I have been modifying a Haas UMC-750 post to work on our Mazak 530 with 5 axis trunnion. I am stuck on how to get the post to output specific code. The code below in black is the current form of the post and in red is what i would like it to due. 

O1000 (OPERATION 1)
(T8 D=0.375 CR=0.03 - BULLNOSE END MILL)
(T13 D=0.3937 CR=0.0394 - BULLNOSE END MILL)
N100 G90 G0 G94 G17 G80 G40 G49
N101 G20
N102 G53 G0 Z-10. (REMOVE THIS BLOCK)

G53 G0 Z0

G53 X-29. Y-8.

I am only looking to have this change to the beginning of the program and still use the Z-10. safe plane throughout the rest of the code. Attached is the post I have been modifying.

Hello,

In order to get the desired output you have to change the properties: forceHomeOnIndexing to NO and useMaximumMachineZRetract to YES.

Please test the modified post carefully.

The code listed above has those properties changed as you have described, however when I posted that code I was changing the properties manually. The code would not have generated that way otherwise. At the beginning of the program I would like to have the spindle go to Z home and then preposition above the trunnion. This is a safety factor due to the fact we occupationally run other parts in the machine and do not want to crash. The trunnion sets in the machine like it is a B/C rotary but  the controller is set up to only read A/C rotation. This allows us to run 3 axis jobs in the machine at the same time.

I understand, did you test the postprocessor which I have attached in the previous post?

[weber63]

I have been running parts with those properties changed for several weeks now. However I am having to manually edit the code with blocks in red. 

[ivan.stanojevic]

I think that we have misunderstood each other.

I have modified the postprocessor according to your needs.

Please test it and update me if it is ok.

I will attach the post again.

Sorry for the misunderstanding. I think I need to slow down on the coffee and read a little better.  I have tried the modified post. It fixes my needs at the beginning of the code but now when the tool finishes an operation and moves to the next it is sent to retract safe plane, then to Z home, then to preposition location. I would like it to only move to retract safe plane between tool operations.

@weber63

No problem at all. 

I have modifed the post and now

N217 G53 G0 Z0.      
N218 G53 X-29. Y-8.

will be printed out only at the beginning of the program and after on tool changes.

Please test it carefully.

Everything runs great on machine. Thank you for your help.
