Help with safeRetractDistance (5Axis)

[Anonymous]

Hello, People!

What I need:

* Modify The pp so the onRewindMachine (assuming is the right configuration to my problem) don't cut my work piece (see in the video second 18-26).

*I would really like to know the steps to solve this issue instead of just receive the modified post processor!

What I been doing so far:

-First, I am bran new on CNC and fusion 360 world.

-I try to give values on fusion 360 swarf tool like (clearances height, stock top, top of the stock and safe distances) with no success.

-I modify the post processor, in the section "user define properties" on "safeRetractDistance" that is configuration to my machine with no success ( I try many configuration options).

-I been reading the post processor manual and appears that is a configuration on the "onRewindMachine (p. 7-163), and safeRetractDistance (p.7-164)" the solution of my problem.

I am saying this because the configuration of my machine "B and C Axis" can not cyclic and needs to be in safe distances.

Thank you in advance.

I use Mach3 to move my 5 axis machine head to head.

However mach3 pp is not optimized to work with my 5 axis machine so that's why I am modifying a different post processor.

I am updating the mach3 configuration, fusion 360 file, and the post processor I am using.

Hello @daniel_lyall,

Thank you for your support!

I try the solution presented in the forum but unfortunately, it did not work.

I try the configuration given and then I try to modify around with no success.

It appears that is taking into consideration z movement on the XYZ and BC mvements but the problem is when the angles of the C axis are to short, it just go the other side with out elevating the Z axis first. May be is something to do with the "onRewindMachine".

Any way thank you so much for your suggestion! I will keep you inform about my advances!

I was trying  the swarf function manually (like 3+2) axis but even if I did manually on 4 different path (each path straight line), the machine still crash (I believe the onRewindMachine activate) with the stock wen rotate.

I try to modified bunch of lines (true, false, adding values, increasing, modifying the zIsOutput, adding values on safeRetractDistance, or traing to modify.

I almost believe that is something missing on my code or something else is forcing to stop any change when trying to get values.

Any advice of how can increase the value of the onRewindmachine?

@Anonymous  give the attached file a go it is basically a 4 + 1 toolpath that was used on a 5 axis machine, it is a redacted model.

Hello, @daniel_lyall 

The file has not tool path, it just have the file.

You were suggesting to make the tool path with the file you send me, or the file that you send me is suppose to have the tool path programed?

any how let me know and I will try it.

Thank you.

[daniel_lyall]

There should be 4 toolpaths in that file you may have to expand the setup click on the big white arrow beside setup 1, most times files you export out of fusion the setup is closed.

lol.

Now I can see it.

Tomorrow I will run the file, and I will upload the video.

Thank you.

Hello, @daniel_lyall 

I run the file succesfully!

What ever it is it did not activate the onrewind machine.

I will look the file and try to learn from the configuration (fusion 360). So far it appears that, if the limits are not reach withing fusion 360 my machine can do the 3+2 or even 5!

Now I have a reference point to move foward.

Thank you for your help @daniel_lyall !

One thing I do when editing a post, is find another post or two that has the function in it that you want, then use that as a guide. the Haas Trunnion post has the on rewind function in it.

Hello, @daniel_lyall,

Thank you for the suggestion. Looking forward to make the post processor work in harmony with the fusion 360 and my machine!
