Max arc setting

[bogusmill]

I know I have seen a setting in MC9.1 for maximum arc radius but I don't remember where the setting is located. Can someone help me with this?

[Fred @ Slate Industries]

Its in some of your Toolpaths "Filter".

[wildcat99]

Under Total Tolerance or Filter there are Min and Max arc settings. Is this what you are looking for?

[Hardmill]

You probably seen it in your post.

Thats the setting I'm looking for. we have a Fadal 8030 that doesnt want to machine large radiuses correctly sometimes. I thought it might be in the settings of MC. Our other programer uses a different PC with different settings and I thought it might be MC and not the Fadal. I machined good parts with it today but the other guy wont trust it so he breaks up large arcs to get good parts.

bogusmill,

 

You can set a Maximum Radius output limit in your post (PST) file.

 

This from the MPFADAL1.PST on the CD ->>

 

maxrad : 399.9999 # Maximum arc radius (radius > will be linearized)

[bogusmill]

We installed the posts from the CD but a search of all words using max, did not bring up any maxrad setting. What part of the post does this setting belong in?

[Hardmill]

What post are you using??

In the mpmaster you'll find it in the general output settings.

We are using a MC post that we modified back in version 8 and used uptxt c-hook to work on v9

[Roger Martin from CNC Software]

Just look in your post for ->

code:

---

seqmax : 9999 #Max. sequence number

---

and add the 'maxrad' line below it ->

 

code:

---

seqmax : 9999 #Max. sequence number

maxrad : 999 #Maximum arc radius

---

Of course enter a value that is valid for your use for the 'marxrad' setting !
