4th axis output

[dgriffiths]

I am using a tweaked version of the mpmaster okuma post and getting some strange results on some 4th axis work. I am doing several operations on the top, front and back of a part. When posted, some of the ops on the back are posting at A90 (this is what I want) and some ops posting at A-270. All operations for that side are using the same WCS. However when I post those same ops by themselves the code that was A-270 is now output as A90. I have created the WCS as I have had issues using the back WCS in MCX. Where should I start to troubleshoot this? MD/CD or recreate the WCS or is it a possible post issue. We have used this post for quite some time with no issues so I would not thing it is the post. Any help or ideas would be great.

[JohnW@Kauffman]

I'm interested in hearing the ideas as well. I've only seen this a couple of times on our router, but have made it work the way I want by going into Ops>Parameters>Misc values button on the toolpath tab, unchecking the "automatically set to post values" box, and changing initial values or nutating bias there, but I don't know if that's the best way.

check your direction of your axis on the plane that is putting out the -270, is the X going to the wrong direction in the plane set up?

[dgriffiths]

The x direction is correct. That is the really weird part. I have other operations using the same rotation and WCS and it posts at A90.

[cadcam]

I want to see your file. I think you are not using planes correctly.

[dgriffiths]

That is very possible. However we have programmed hundreds of 4th axis jobs with no issues so this one has us a little confused. I will zip up the file and try to get it on the ftp.

[dgriffiths]

I put the file on the ftp in the MCX2 folder. File is called A270_Output. While experimenting with the file we found that is we ghost out op#4 and post the program that the file is how we want it but with op#4 included it outputs the A270 moves. I have looked through our plane creation and everything seems good. I am sure we are just missing something with WCS/TP/CP. Cadcam, I can email you a copy of the MD/CD and post if that will help. I have looked through the post settings and everything seems to be correct. However my post editing abilities are sub-par at best. Thanks for the help.

[dgriffiths]

I just received the latest and greatest mpmaster okuma post and I am still getting the same results with the A270 instead of A-90. It has to be something we are doing wrong with the construction of the WCS. We found that if we add an operation at A0 in between the ops from front to back it seems to correct the issue. Did anybody have a chance to look at the file on the ftp. We have been messing with this file for a few days now and are at a loss. Any help would be much appriciated.

Have you tried a different post besides MPmaster? I am having a little trouble opening your file (FTP). What kind of file is it? Zip2Go?

[dgriffiths]

Yes, I have tried a few other posts with the same results and we have many others programs that posted fine so I am pretty sure it is something in mastercam or something we have done with our WCS creation. The file on the ftp is a Zip2Go. It is a pretty large file. I will get rid of some of the fixturing geometry and put it up as an mcx.

[Dan@home]

In this case size doesn't matter. No MCX or Z2G extension it has a (rar).

[dgriffiths]

I just uploaded an mcx. filename is A270_output.mcx

[Dan@home]

Best I could get was A0 top, A90 front, A270 back. Even when I posted these alone or all together, same results. I changed your WCS TP/CP to what I thought was less confusing to me. I don't have your Okuma post. I just used the MPmaster. Maybe if you use your post. I'll put on FTP site same folder, as A270_OUTPUT2.

[dgriffiths]

After much experimenting, I have come to the conclusion that our issue is post related. However I am having some difficulty finding the necessary post edits. What I would like to do is set upper and lower limits for the 4th axis output to A-180 and A180. I have found a section of the post that I thought would take care of this but have no success. Here is the section I thought I should be looking at:

Am I on the right track here???

[crazy^millman]

Well looking at your file. You have operation 4 using OP2 WCS and all the others using OP1 WCS. I also posted your program using my MPMASTER and did not get the A-270 anywhere in the post code. Also right click on the operation manager and change your display options to show WCS and TOOL Plane if not using it now.

So not sure what to tell you, but think you are going down the wrong road thinking it is a post issue. I would download the MPMASTER off the website and try that. I would also try the generic 4 axis post and MD/CD

I have WCS on tool planes tuned on. I did notice the WCS on op4 and corrected it. I just received the lateest okuma-mpmaster post and MD/CD and I am getting the same results. I did notice in your code that the A axis values are opposite from what I am getting. I am getting A-270 and your code has A270. Either way it is causing me a problem because the tombstone wants to rotate the part underneath (towards the bed) and there is not enough claerance for our fixturing. This is usually the case with jobs on this machine. If the vaule is A-90 instead of A270 the tombstone rotates the direction I need it to. And Ron you are correct, I do not think I fully understand what controls this (post, MD/CD)??? I will try what you have suggested and see if the results are different.

See know you added a big piece to the puzzle that was missing. It is posting out code correct. What you are trying to do really comes down to some things that might do with shortest distance in the machine definition and then use a point toolpath to drive the operation to A0 then go from there to the 90 positions. I would try this approach and see if it gives you what you want. Also make sure the machine Def has shortest direction, absolute angle(0-360 deg.) on in the Rotary axis.

Ya, sorry for the lack of info, I think we are still trying to figure out exactly what is is we want. The code is fine, I am just trying to eliminate the possibility of crashing the 4th. The point path back to A0 is how we got what we wanted on this program. What I do not understand is that without it the rotations are not constant. Some rotations in the program go from A-90 to A90 which is what I want and others which are the same rotations go from A-90 to A-270. If the rotation back to A0 first is the solution that is not a big deal. At this point I am just trying to understand what determines the rotation direction and why there would be two different results when rotating between the same two WCS. Thanks again for the replies.

Well WCS might be your trouble here. Have you tried this only using the top WCS and no others WCS's???

If I understand what you are asking, yes. I basically started over from scratch and used All top WCS and for the tplane used front and one created plane (back) and the results were the same.

Man I would be pulling my head out of my hair at this point. Well if you want a fix to make good code do a mi to replace the A output and use it to force it out. Then just put the value in mi and make it replace what ever it puts out to give you what you want for posted code. Do a search on force out A axis I think a did a good explanation on this few years back.

Yeah, It is really starting to p$ss me off now. The post MD/CD all work really well other than that one issue so I think we will just take another avenue to accomplish the A rotations. Thanks again for all your help.
