C-Axis mill/turn trouble on Mazak (EIA)

Hi,

Im new to mill/turn and i just started with Mazak MSY250, i have a problem when it comes over 360 degrees and starts over again on 0 instead of keep going it switches direction and mill away everything it comes over.

Is it an option in fusion so it keeps going over 360? Or is it something in the machine im missing?

This seems like a problem with your post processor. What does you machine configuration look like in your post?

Yea maybe it is, because it also puts out M901 and it doesnt read it, and also G53.5, i have to change this to G53 by hand.

Do you mean like this?

The Mazak Quick Turn 250-MS post processor probably needs to be modified.

Inside the post try looking for a line of code that reads like this:

var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], cyclic:true, preference:0});

the cyclic argument means that the axis can rotate indefinitely. If that argument is a range instead, then the C axis will rotate to 360 and then turn back to 0 to start the rotation.

If you would like you can attach the Mazak Quick Turn 250-MS.cps file and I can take a quick look

Can you send me a screenshot of your CAM setup? I want to see what kind of operations you are using

Okay, sorry for all the back and forth. If possible please attach the fusion project, then I can test and see where exactly the issue is coming from

It looks like i cant just share the link, do you know if there is any other way so you can see the operations?

Hey @Oliver_Lidstrom01 , I tried to find the issue but I was unable to. This definitely seems like an issue with the post processor itself but I am not experienced enough to find the problem. Good luck.
