Altering post for Tool Change

[M&GToolWorks]

I have an old dinosaur Bridgeport Interact, FANUC machine, and I have been using the Generic FANUC post without too much issue. 

One thing I have to constantly change though is the tool change line. 

This machine requires a G30 G91 Z0 included with the Tx M6. 

I changed a post for a previous employer for HSM, but either I am missing something or I cannot seem to edit the Fusion post the same way?

It can be edited but the generic ones distributed in the installation can't be, they are read-only so that they won't be modifed and then overwritten by an update. If you open it and save into a non-write-protected directory you should be able to edit the post just fine.

[M&GToolWorks]

Thanks, saved the file as a new post (Interact) and can edit. 

I see now I will need more help than I first thought with this. 

Typically I manually enter my code something like this: 

N30 G30 G91 Z0.0 T18 M06
N35 G90 S750 M03

To write the G30, I do not see it listed? Would that fall similar to the G28? gFormat.format(28)

Modified?

writeBlock(gFormat.format(30), gAbsIncModal.format(91), "Z" + xyzFormat.format(0),"T" + toolFormat.format(tool.number), mFormat.format(6)); // retract
writeBlock(gAbsIncModal.format(90));

ORIGINAL

writeBlock("T" + toolFormat.format(tool.number), mFormat.format(6));
if (tool.comment) {
writeComment(tool.comment);

A few test posts seem to confirm that works. 

Can I have someone please double check me and verify that looks correct? 

thanks

[Steinwerks]

It looks fine, but the true test is using it on a daily basis of course. There are usually a few places that G28 shows up so be aware of how the post handles it (things like retract in the onClose section) but considering that (I suspect) you're not doing things like in-process probing I would expect that it'll be just fine.

Congrats! If you run into unexpected behavior, don't hesitate to come back and describe what you're seeing. It's also helpful to attach the post .CPS file so someone can take a look directly, as issues can arise from simple syntax errors as well that can be hard to spot.

Read through what it posted. Carefully ran the first piece. 

Post works great... 

Thanks! 

Ohhhh how I miss probes... was fortunate to work for some companies with really good equipment. Macro's with in process probing and multiple tools to account for wear running hardened parts. 

I will take being self employed running this old dinosaur any day. (Maybe not every day )

Ok, so what did I do wrong? 

Started Fusion up today to post a program, post is gone, like it never existed. 

When Fusion closes does it edit/change things? Part of the whole cloud deal? 

[Steinwerks]

Where did you put the post processor file? Did you try reselecting the directory it's in?

[M&GToolWorks]

I saved it in the post folder with all the other posts.... Posted during the week with it? Computer restarted saturday and Fusion did its update thing. Does Fusion wipe posts if it isn't their post? Am I supposed to save it somewhere else? 

[GeorgeRoberts]

Hello,

It is always best to save your posts in a different location. When Fusion updates, it replaces the posts in the default directory with the latest available versions.

[M&GToolWorks]

I am ignorant to this whole cloud concept, what else do they wipe/change/alter without informing you? 

Is there a list somewhere or do you have to find all this out by trial and error? 

[Steinwerks]

@GeorgeRoberts

I thought that folder had been made read-only in the last few updates? I know the posts are now, perhaps this is something that needs to be addressed.

@M&GToolWorks

It has been covered in many, many posts here but I agree, it needs to be more straightforward. Best practice is to add it to your Cloud Posts or an alternate directory. The default posts folder has always been overwritten for every update as the generic posts are updated as well on a regular basis.

[M&GToolWorks]

What is a Cloud Post? I don't see that in the selection of posts? 

"The default posts folder has always been overwritten for every update as the generic posts are updated as well on a regular basis."

Guess I missed that in the instruction manual.... 

[Steinwerks]

Agreed that it is not perfect. Here's a link to enabling cloud posts: https://knowledge.autodesk.com/support/fusion-360/learn-explore/caas/sfdcarticles/sfdcarticles/How-t...

Alright, got everything changed back to where it was.... geez.... 

Didn't bother with the cloud post thing... realized when I don't have internet I won't be able to post... 

[Steinwerks]

I believe it's more of a sync thing, as it should still keep it available if you are offline.

At any rate, I actually keep mine in a Google Drive folder that syncs, and you can keep it in any directory on your computer that you want, you just have to browse to it.
