Postprocessor for 3+2 axes MAZAK

[martynas.rKKLK9]

Hello, is it possible to edit stock mazak postprocessor, to the one with 3+2 axes.

On the Mazak maschine, i have a vertical table named as C axe, and the head +-90degrees called B axe.
Can someone please help me?

Hi @martynas.rKKLK9

Search for function defineMachine in the stock Mazak post and then replace the following 4 lines.

if (true) { // note: setup your machine here
var bAxis = createAxis({coordinate:1, table:false, axis:[0, 1, 0], range:[-90, 90], preference:-1, tcp:true});
var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[-360000, 360000], preference:0, tcp:true});
machineConfiguration = new MachineConfiguration(bAxis, cAxis);

Well, now it generates the code without the alarm, but it doesnt work on the actual maschine.
I am getting error:

801 SIMULTANEOUS AXIS EXCEEDED

At the end of the program, everything seems to be allright, but at the beggining there was no GO B45. C0.

Also, here is what it generated:

By the way, thank you for reply

From what you describe it might be worth also changing this line the post to true
var useABCPrepositioning = true; // position ABC axes prior to G68.2 block

Does the controller show which line in the program generates the error? 801 SIMULTANEOUS AXIS EXCEEDED

[martynas.rKKLK9]

Changed it, and it gave me the same result.

The maschine gives me error on this line:
G53.1

I think at the beggining there should be a code like G0 B45. C0. 

but im not sure why, it doesnt appear

[phil.lewis_bham]

Thanks for the feedback.

After that latest change I would expect G0 B45. C0. to be output just before the G68.2 line. Is it there?
You could try manually editing the program to add it earlier in the program to see if that makes any difference.

As it errors on the G53.1 line another thing to check is that G68.2 support is enabled on the controller.

[martynas.rKKLK9]

Tried it, now it seems to be allright, at the beggining of the program it gives me G0 B45. C0
But still, im getting the same error 801 SIMULTANEOUS AXIS EXCEEDED on the G68.2.

Sadly, but i could find the option for enabling G68.2 on the controller.

Maybe you have a clue where is it?

[phil.lewis_bham]

Unfortunately I do not know how to check this on the controller, so can only suggest you ask the machine supplier.

Morning @martynas.rKKLK9,

I am finding a similar error with our Mazak, The machine is alarming out on the GO B-6 line above the first G68.2 line with the 801 Simultaneous Axis Exceeded
