you bet hood
but i still have a problem mastercam is posting in radius with the mach3B post and when i change the post to fanuc it is ok posing in diameter but fanuc instead or i,j they use r so in mach3 they will come out circles
i need a mach3 post for mastercam that post in diameter
can some one help me !!!!!
-
Strange, I work in Dia mode and use R for arcs and its fine, did you try changing the reversed arc setting again after you used the new post processor?
Can you attach a bit of code that you have issues with and I will see how it looks for me.

dear hood
belive it or not now it is posting in diameter and it is a fanuc prosesor and mach3 is fine with it
but dont ask me what i did cause i dont know
do you use mastercam to generate gcode?
-
Thats god to hear :)
No dont have MasterCAM.

Hmm....
You just shook the memory here, i don't use MasterCam, but Dolphin has a few different post processors for the
lathe, ie one for radius and one for diameter. So may be similar. Additionaly check if there is a turning mode that you can be in
when bringing in the file as that could just be a click and you may have mistakenly done it.
FWIW,

Dear rich
yes you might be wright
im just exploring the mastercam it is a bit complicated compare to the lazy turn but it is a verry good cam and also i need to practice alot

No FRO on Queue option set?

I don't know if this is the same problem i had but latest version of mach would take all the radius moves and make circles out of them or a figure 8 i had to delete that version and go backwards in version's to correct the problem working fine now.

i did try it but with no luck the only thing that i set was (look ahead 20lines) i adjust it to 1 and then after that code line it will bup up but you still have to wait for the other line then
-
Can you attach your xml please.
Hood
-
how can i upload a XML file i made a copy with a pendrive but i dint know how to upload in the forum page
-
i think here is the file
-
Ok first thing is uncheck No FRO on Queue
Then if it still doesnt work then I think you may have an issue with the screenset as I can adjust the FRO no problem with my own screenset but the standard Turn one doesnt seem to work.
Will have a look see if I can find the issue with the standard screenset.

Ok seems to be the OEM for increment feedrate that the turn screen uses are acting weird. On my screen I use OEM108 and OEM109 and it works as it should so try this screenset and see if it works.

dear hood
it worked perfect !!!!!!!!!
many thanks for your help

No probs, will note this down and make sure that when/if Brian ever gets on to Rev4 Turn it will be fixed.
