Okuma LB15 lathe post problems

[k_barry]

We have a problem with our post for an Okuma LB15ii lathe with on OSP 7000 control. It has a C axis as well.

We have 20 seats of Mcam. (Education institution) 15 are still V9, a couple of X2 and a couple of X3. (We have budget restrictions)

We want to upgrade them all to X4 but our lathe post does not work and our reseller either can't or won't supply one that works in X2 or X3.

Our reseller changed the V9 post the way we wanted it. When we got X2 we used the Updatepost.dll file to update the post.

It seems to have worked ok for our mill but the lathe has problems. We have been in contact with our reseller and he has sent us another post that doesn't work. I think originally we used the MPLOSP7 in V9 and our reseller customised it to suit us.

This has been going on for ages.

The main problem is the start of each tool. It doesn't call up a tool at all.

 

This is what is coming up at the start.

But we want the following, which we used to have.

M08

G96 S200

The end of each tool is not correct as well but if we could get the first bit done its a start.

 

Thanks in advance

Not sure where that output came from, but it would certainly be bad news

Can you do a .z2g with a sample part make sure to check the post option when doing the .z2g and send it my way I will be glad to take a look at it for you. I have a pretty tricked out LB15 post for our machine. With the G13 I am assuming you have a lower turret. If you do would you like Mastercam Sync turning added to the post? It is a little crude, but something is better than what CNC offers for dual turret machines which is nothing!!!

maybe a facing canned roughing cycle without any stock defined so x0z0 is the referenced stock

[k_barry]

Thanks for the offer Ron.

I have sent you a job.

No we do not have a lower turret so the G13 is not required.

Kevin,

 

Did the G13 come from the post update? If this was a V9 post there may be an issue with the Machine definition

[k_barry]

Greg

The G13 came from the post update. I have had a look at the machine definition and changed a few things thinking I will delete the lower turret (it was showing a lower turret) and I may have stuffed things up a bit. I haven't done anything to the machine definition as it looks a bit daunting after using V9. I think I had better delve into the help files a bit. I just read the Mastercam getting started manual but this didn't explain much of the settings.

It still posts a G13 and still doesn't call up a tool.

K_BARRY Email me a file and I'll take a look for you.

 

We have two LB15's here that I have updated from V9 through to X4 with no problems.

 

Are you in Victoria?

Are you setting this up at Dandenong or Moorabin?

Kevin is in Newcastle. If you get stuck please drop me a line and I will see what I can do. Bob will be off deck for the next few days

[k_barry]

Hi Greg, David.

 

Bob has sent us a fix today.

He has changed our machine definition and if we set Mi to 1 we will get a toolchange.

Looks promising. At least he is looking at it for us. We haven't checked too much yet but it looks better.

Thanks for the offer of help.

[DavidB]

Thats great it's being looked at. Is the MI a temp fix?

You shouldn't have to set a Misc to get a tool change, agree Greg?

No.

 

I don't have the post and there are endless possibilities as to why this Misc integer needs to be on. At a guess it maybe associated to using a fixed home position

[k_barry]

Hi

It is Misc Int 1 which is Home position.

 

Thanks

Kevin
