Hey everyone, I wanted to modify my MPFLAN lathe post for my haas TL1 I wanted to change

 

instead of going home at end of tool I want just a Z6.0

 

at end of each tool, output a M00 after Z6.0

 

I 'll be out until mon thanks for the help

I would suggest NOT hardcoding this.

 

Set your toolpaths up to goto the machine location and set your machine location.

That makes more sense, I'll try that

 

Thanks

John,

"I would suggest NOT hardcoding this." Why not? Just want to know becouse I'm new to the whole "lathe thing".

Because there is no guarantee that those numbers will never change and if you "forgot" you might have a BIG problem. IMHO, it's better to maintain control of your positioning in the setup/program.

 

Those numbers can be set in your machine def and you can access then when on the tool paramteres page.

 

Why hard code what is readily available and take away flexibility?

Let's say for this job you have a boring bar that sticks out 5", so you program clearance moves to Z6.0 and make a tool change. Next set up has a boring bar sticking out 6.5". Go to Z6.0, make a tool change and CRASH! Better to change in Ref Return for each operation.

Besides when you "hardcode" a post. Mcam has lost it's recognition of where or what the machine is doing. For example: if you hardcode a "M09" in your post, as far as mastercam knows the coolant is still on. It does not recognize hardcoding.

While I agree that hardcoding clearance moves is a poor idea, I run a lot of hardcoded lines in my posts; it has its place. Let Mastercam do what it can, spit hard code for the rest...

I agree Chris and also if Z zero is the face of the part, then a Z rapid of Z6.0 will always be ok.

Don,

 

You're right. Maybe crash wasn't the right term to use, but an Overtravel alarm could happen.

 

Edit: A crash could happen if the tool you are indexing to is longer than 6".
