I went in and modified the code by hand and put in G54.4 P0 before the rotary move and then G54.4 P1 after it and it didnt alarm out, only unit it reached another rotary move where A was at -90?? Do i need to cancel the code before any rotary movements?

The program ran for a while and then this happen? Illegal Command in G54.Is this something to do with the C180?

When i select the g54.4 on the misc value page and post my code it does not post a G54.4 P1. Can I simply go through and find and replace G54 with G54.4 P1?? Or is there more to it than just replacing G54 in the code??

Just checked the Mazak probe documentation and #140 and #141 are error for x and y! Thanks for all the help! It is greatly appreciated! I will be able to verify it at the machine on Wednesday. Hopefully this thread has made a resource for others to help understand it as well. Or it may just be that I am the only g54.4 dummy...:)

So after each probe cycle this will automatically load the correct deviation from COR into G54.4? Do i still need the actual S value for G54.4 on the G65 line? or will the following macro code do the work?

If im understanding correctly Im going to set G54 to COS. and use my probe to set G54.4 P1, i could store it in say G55 (S2) and use macros to get it into G54.4 P1?? Here is the code i came up with to get the deviation put into G54.4 P1., Im using #100 as a place to store the values, G65 P9812 Y15.6 Z-1.75 (?? set G54.4 P1) (X YEB) G65 P9812 X1.75 Z-1.1 (?? Set g54.4 p1) (Y WEB) #100 = [#5811-#5221] (SUBTRACTING THE PROBE READING FOR X FROM COS) #101 = [#5812-#5222] (SUBTRACTING THE PROBE READING FOR Y FROM COS) #5811 = [#100] (sets the deviation in G54.4 P1 FOR X?) #5812 = [#101] (sets the deviation in G54.4 P1 FOR Y?) Does this look reasonable??

This is great info, I am using these lines to pickup the part, S1 would be the code to probe set G54, would i do S101 to set the part at G54.4 P1?? G65 P9812 Y15.6 Z-1.75 S1 (X YEB) G65 P9812 X1.75 Z-1.1 S1 (Y WEB) Also another question was on the Z for center of rotation you put in -42.889, but the parameter says 0, where did that number come from?? Thank you so much, excited to get back to the shop and try this out, will let you all know if it is magic!!

Hello all, I am new to 5 axis machining, and the company i am working for just bought a new variaxis i600 and got it up and going a few months back. while i have had a few successful parts programmed on this machine. This one i can not figure out. We are having to machine on an extrusion that has most of the OD surfaces finished, and we have to machine pockets into the sides and various features on every side. We are holding the part in a 5th axis vise, on the center of the table.and probing x0y0 at the center of every part. I am sure my part is on center in master cam 2017 and everything looks good as far as geometry and numbers go, but when i run the program everything is .01-.02" off center?? and inconsistent from part to part... We checked our setup, and the probe. my last conclusion was that it had to have something to do with the changing position relative to center of rotation?? Because Y and X are changing several thou when i look at the work offset page. Does this sound like something G54.4 would help resolve? As ive never had much issue with parts machined from a solid billet, its just when having to be on center of an existing part with finished surfaces. Does anyone knows anything that would shed some light on this??? It seems even Mazak and Mastercam are not able to help much with this issue... Thanks
