Posting A-59.999 not A-60.?

[Eric S.]

Eric braces for a verbal lashing...hehe

 

First off I am a registered user so please do not bite me .

 

I am getting a little picky here but I am using the mpmaster post on my haas VF2 with the 4th axis. It is working well but for some reason it adds .001 deg to all of the A moves?

 

eg. A-60. posts as A-59.999

 

This is not a big problem I know but I am wondering if someone may know how to fix this?

 

Thank you

 

Eric

Eric,This is weird.

I use the mpmaster that I have modified (with help from my fellow forum members)and I do not get this.

Is there any way you can put a file on the ftp so I can post it with mine to see how mine comes out?

I would be curious.

BTW my rotary moves are always in the + direction.

[Eric S.]

K I'll try and get one up I'll let you know.

[Eric S.]

Ok Bucket

 

I put an example of my problem on the FTP site in the mc9 file named "60 DEG ROTARY.MC9"

This it how my mpmaster posted the A move:

 

N14 G00 G90 G54 X-.3125 Y-.875 A-59.999 S15000 M03

 

Thanks for your time

Eric

Try change formate like this see what happens

I am not sure

 

fmt A 4 cabs #C axis position

fmt A 4 cinc #C axis position

fmt A 4 indx_out #Index position

ok,here is how mine posted.

As I said,I always rotate positive.

G43Z1.H4M8

Z.866

 

not sure but it must be something with your post.

do you know exactly the mods. that you have done?

Well here is the code to change the postive/ negative vaule of the posted code on the A axis.

code:

---

rot_ccw_pos : 1     #Axis signed dir, 0 = CW positive, 1 = CCW positive  

---

Here is what the vaules are on the A axis:

code:

---

 fmt  A  11  cabs        #C axis position

fmt A 14 cinc #C axis position

fmt A 4 indx_out #Index position

---

I dont have the dongle to play with your program tonight but will look at it tommorrow and see what I coem up with. I would ask do you get the same results when posting this using another program.

Yea Eric,

Try posting this with a "unmodified" mpmaster post and see what you get.

Seems to me that something was changed in your post to make this happen.

Another possibility is the number of decimals in the NCI file. Eric, if you go to Screen -> Configure -> NC Settings, what have you set as 'Number of decimal places for NCI'?

 

The angle is calculated from the tool plane matrix, and the tool plane matrix is a unitary matrix (i.e. each row or column is a vector with the length one). To get accurate output in multiaxis, the 'Number of decimal places for NCI' should be set to 6 or more.

Christian Raebild ,

You my friend have solved his problem!

I just changed my config. to 4 plcs. then posted one of my programs,and I also got a .999 "A" move.

 

Great job on solving this one.

 

This is what makes this place soo valuable.

You cannot put a price on this kind of help.

Good morning all.

 

Thanks for your help guy's! Christian Raebild, the number of decimals in the NCI file was the problem! That one has been bugging me for a long time now, it'll be so nice to have it proper.

 

Hope you have a good weekend! I'll be here working

 

 

Thanks again.

 

Eric
