4 axis post problem

[Goldorak]

when i verify or backplot the angles seems ok

0 deg 90 deg 180 deg and 270 deg

 

i use axis positionning about x

machine is okuma mc-v4020 w/ osp100m control

 

 

when i post it output 0-90-180-90 instead of 270

 

same thing happens when i reverse it output 270 instead of 90

 

the 0 and 180 is always correct!!

You're likely having planes issue.

 

When you work on Back and bottom planes you are always better off creating new planes and not using the system back and bottom. Mastercam has always been a little squirrelly when trying to use them.

Axela

go to the machine def and right click on the axis you are having problems with click properties. you can set and adjust the angle in here or you can do it in the post processor. the limits may need to be set.

Most 4 axis post processors have problems in certain cases , but if you ask your reseller to contact us, then we can surely deliver a post processor that can give you the correct angles in all cases

 

We have made 4 and 5 axis post processors for machines with Okuma OSP 100M controls before, but I do not remember whether we have made a post processor for that specific machine. I am having holidays at the moment , so I cannot check that before I am back at the office on September 3rd.

again

 

 

in my post when i set rotary axis at

 

code:

---

 index        : 1     #Use index positioning, 0 = Full Rotary, 1 = Index only 

---

all my a axis command is ok BUT when i dont use 4axis it outputs the M15A0 even if the rotary axis is unchecked in my operation

 

 

at oposit

code:

---

 index        : 0     #Use index positioning, 0 = Full Rotary, 1 = Index only 

---

it index at wrong angles !!!!!

 

BTW i contact my reseler i just hope than somebody here had a way to correct my problem !!!!
