Want to output arc moves at helix entry

[DaveR]

Currently when I have a helix entry to a pocket I get small single line moves as output when I post. I'd like to get arcs as I get a little herky jerky on entry moving at 180 ipm.

 

I checked "output arcs" in the tool path dialog, also checked arcs supported in the control def. I still get line moves.

 

Anyone know what I need to change to get arcs?

[Guest]

Dave,

 

In your control def >> arcs

 

Make sure support for arcs in the planes is checked

Arc type delta start to center

 

And

 

Helix support is checked

[Teh Bear without Brains kinda idiot]

linerize-off

[cadcam]

Dave you need both options set as the guys have stated. But sounds like you Need Johns first so the post will see what Mr Pooh stated.

[DaveR]

John's suggestions are done, where is linerize? Looked all over for it in the control def, is it hiding somewhere else?

[gcode]

The helix ramps are linearized by default. There will be a check box in the Operation that says

"output arcs"

[DaveR]

Yea I got that one checked too, gcode. This is a standard pocket tool path BTW. Still getting tiny line moves. Using the stock Haas 4x post.

 

Still can't find linerize anywhere.

[gcode]

 

If this is checked, you should get G02/G03

helix arc entry moves. If its uncheck you'll get

a bunch of tiny G1's.

If you don't get arcs, there is still something wrong with your post

or

your pocket geomtery is not perpdicular to the Z

axis. If you pocket chain is even a tiny bit out of square, Mastercam can't output G02/G03 helix arcs but I would expect you'de get some sort of error in that case

Is you pocket chain wireframe or a solid chain??

 

 

This is how your post should look

[Guest]

Also Dave are you sure your getting a helix entry on the tool path?

 

Sometimes the amount of XY clearance has the be smaller than the default. If it's a tight area you might try shrinking that down to .02. That number being to large for the area being cut can cause the helix entry to be skipped.

[DaveR]

How strange. I have all of that set as you posted. BTW thank you for the pics and explaination.

 

I get a clear helix entry (tiny XYZ line moves) in 4 places in this pocket. It's based off of a line drawing / boundry and everything is at Z0.

 

Would one of you look over the file for me if I can post it on the FTP this evening?

[Guest]

Not a problem Dave

[gcode]

Put a zip2go on the ftp ( or email it)

so we have a copy of your post and machine

def.

We are missing something somewhere.

If you switch to a default mastercam machine

do you get helix arcs???

[DaveR]

OK I made the zip to go, logged onto the FTP and when I try and drag the file onto the FTP my windows tries to open the file instead of dumping it in there.

[Guest]

copy and paste it Dave

[DaveR]

Edit

 

Dah...wrong file. Hang on...

[DaveR]

OK it's under MCx2 files "Baja a arm roughing" zip 2 go file.

 

Thanks

 

been a tough day sorry bout that.

[Guest]

That what you want Dave?

I opened your control def on the arcs page it was set under helix support for none.

 

I changed it saved it and it outputs arcs

[DaveR]

OK, I changed that last night, did not make any difference. How did you change it?

 

I just opened up the control def and changed it, saved it, no change in the code. I must be doing something wrong there.

 

edit

 

I just looked again, mine says arcs supported in all planes?

 

 

OK. I got it. I needed to access the control def from the machine def page. I missed that pop up window last time.

 

Thanks for getting that sorted . me>

[Guest]

Make sure you access the control def through the settings >> control def.

 

That will make any changes permanent, while if you go into the OP manger and edit it there it will only be in the one, once you change it out, it will revert

 

I placed a jmp_baja file on the ftp, grab that and post it with the included defs and post, any difference?

[gcode]

Dave

On the Arc page of Control Def there is a block

labeled Helix Support

The Control Def you sent me had

"No helix allowed" checked.

I changed it to

"All planes supported" per the picture I sent last night and it is outputting arcs now

 

When you edit your Machine/Control definitionsmake sure you do it from

Settings/MachineDef.

 

Edits from the Edit button in the OPs Manager only affect the current file. If you do you edits from there, you'll be doing them again the next time you use this machine

[DaveR]

Alright, I got it now. Thanks to both of you for the help.

 

Dave

[Guest]

Did you figure out what it was you were missing Dave?

 

I just saw you edit, glad you got it figured out
