.MMD or.Control or the post ???

I'm using X2

Generic Mill 4-axis VMC machine definition

Generic 4X Mill Control & post.

 

I have a VMC 3 axis Robodrill with a 2 axis/tilt table. Rotation is C, tilt is A.

 

When I post, the rotary axis comes out as A and I need it to be C. Is that done in the Machine Definition or Control file or the Post?

 

The way CNC software talks, everything should be able to be configured in the Mach Def & Control screens but this seems to not be true. I already tried changing the Machine Coordinate from A to C under Machine Def Manager then double clicking VMC A-Axis but this didn't work.

 

Thanks

I would change it here:

code:

---

 # 5 Axis Rotary Settings

# --------------------------------------------------------------------------

#Assign axis address

str_pri_axis "B"

str_sec_axis "A"

str_dum_axis "C"

 

#Toolplane mapped to top angle position strings

str_n_a_axis "A"

str_n_b_axis "B"

str_n_c_axis "C"

You are going to need a 5-axis post for proper output. I would suggest contacting your local reseller for help.

I don't see that in the Generic 4X Mill Post. I don't have the 5 axis option as I don't do any 5 axis work nor have a 5 axis machine. Is there someplace else to make this change?

[Zbuilder]

Oh, I do have the post but will it work for 3 & 4 axis without the 5 axis option?

 

Thanks

Ok, under this #Rotary Axis Label options

I changed

srot_x "A"

to

srot_x "C"

 

It seems to work. Don't know if it's the "correct" way to do it though.

 

thanks all

Ok this is weird .. I'm answering my own questions. I found a better way to make this work. Undo what I posted earlier & change

use_md_rot_label : no$

to

use_md_rot_label : yes$

 

Then under Machine Definition, Machine Base, Table Group, double click VMC A-Axis & change General Info, Machine Coordinate to C.

 

Hope this helps others.

Just saws this. You could have just gone into post under program and debugging switches. Find this line

scaxadrs A #Address for the rotary axis

 

change to

 

scaxadrs C #Address for the rotary axis

 

tried it and this would have given you the desired C output as well.

Hey Mike, It's Rich from Insulfab. Remeber where we went into Machine Def & changed the A to a C & nothing happened? Well changing the use_md_rot_label : no$ to a yes$ makes it work now. I guess they have the switch off by default.

 

Thanks

Sorry I didn't see this sooner. But as you can see there is a lot of help here.
