Brother Speedio Blum post

[adrianthong]

Hello, I'm using Renishaw probe with Blum software. The main program is 8700 but when I post, it puts an absolute move instead of an incremental move. How can I fix this in the post?

Hi @adrianthong,

All probing from Fusion 360 is absolute not incremental. 

Think of Probe WCS as refining a datum rather than outright setting it. 
We need to roughly have the datum in the right place and then we will use absolute programming to refine the datum. 

Using functionality like "Overriding WCS" can mean you don't have to keep manually setting your datum.

Richard, I understand how that works on my Haas, but on the Brother/Blum 8700 program if I run the program as posted, it will want to move 3" to the positive side, triggering an alarm for not finding a surface. What am I doing wrong? 

I think I have to add an "A1" to the line of code to be absolute?
