Hi guys.
With LazyCam i can import a drawing but then i don't know where i can set my tool's settings.
Can some1 explain me this?
Thanks
-
After you import a DXF file click the Layers tab at the bottom of the Info window, press the tool button and input the name, diameter, feed rate and so on.
-
Thanks.
Is there a way to put the measouring unit in mm? Because i work with mm but i can't find where i can change it.
-
Hi, Saumur
LazyCam works in Units, If your DXF is in MM, Then it's MM in LCam.
Thanks, Chip
-
can you work in diameter mode with lazycam?
thanks
-
anyone?
-
Hi, Saumur
Lathe uses a Profile top half of your dxf drawing.
Hope this Helps, Chip
-
Guys, i'm sending you the dxf i'm using.
If you can tell me how i have to configure lazycam to generate a g-code of this i would really appreciate it since i can't do it...
Thanks
-
I could do the g-code but i don't understand why when i put the tool it's like the program is not reading it.
In fact if i change the diameter of it the program will be the same.
Do i have to do something in Mach3 too?
Thanks
-
Hi, Saumur
Is it a Lathe profile your looking for ?
Your dxf diden't clean up weii, Loaded it in BobCad, traced it and saved under dif name.
Is this what its should look like.
Thanks, Chip
-
Chip,
yes it a lathe program. Your drawing isn't correct.
Anyway i would like to know why when i create the g-code the tools settings i put don't change the code, it's like they don't get read.
Can you tell me how can i set up my tool?
thanks
-
anyone can help me please?
-
Hi, Saumur
I think you can create them thy will not load though, New LC lathe is in the works, Drought there will be any changes hear.
Thanks, Chip
-
so in other words at the moment LC is USELESS for lathe?
-
I mean, if i can't set the tool i can't make a correct program. Can i set the tool in Mach3 or what?
If you could help i would really appreciate
-
Saumur,
What did you draw the profile with ? I have old cad and cannot open your dwg and your dxf will not work here.
I made a rough profile similar to yours and Lcam seems to do well with it here.
Is this similar to what it should look like ?
Maybe send your dwg file.

Hi, RC & Saumur
I had the same problem with the dxf, It loaded weard.
Hears the dxf loaded in rino then bobcad, I think this is correct.
Hope this Helps, Chip
-
Hey Chip,
This is what your tap looks like on mine.
Can you put the vertical line for the stock size on the Z+ end and resend the dxf ?
Thanks
-
Hi, RC
You've got Mach set in Diameter Mode, In Ports & pins, Turn Options.
Hears a dxf ver line z+.
Thanks, Chip
-
much MUCH better, I forgot that I went back to dia mode.
The toolpath reduces to very light cuts in the saddle area. Looks like they go to the finish cut increment.
Thanks Chip,
RC
-
Hi, RC
Like this.
Chip

Guys,
thanks for your answers, yes the drawing you do is correct.
I'm sorry if i do to you stupid question but i'm a noob of lazycam, so i would like to know if you understand what i'm asking you.
In my piece i don't have to do a roughing pass, only a finish one.
I have a round tool with2mm radius. I wanna know where i can input these data and change them when my tool lose something on the radius.
Anyway my dxf works fine, but when it creates the g-code it makes some G0 movement of 0.0002 mm that are useless. DO you know how i fix this?
the MAIN problem is that i don't know where i can input my tools information (radius ecc...) since if i put them in lazycam it's like it don't read the informations.
If you can tell me how to do this i would really appreciate.
Thanks

Hi, Hi, Saumur
Post #16 has a dxf and tap file that should do what you need.
Jog mach3 to the Diameter / Start point you need, Then Zero your Z and X axises.
There is no tool offset in the G-code, Should work fine.
Hears a LC LCAM file also, I Cleaned, Optimized and moved the 0,0 "target" to the right side.
Then just click "Post Code" Button will generate the profile to Mach3.
Hope this Helps, Chip
-
Hey Chip,
YES to reply #20.
Do you Know why it does that?
In creasing the finish tol. seems to help....but it shouldn't.
Thanks,
RC
-
Hi, RC
It's probably some typo or error in prog code, Woo nows.
It was getting pretty close then no time to finish/debug.
Thanks, Chip
-
Looks like ART is really rolling along with LTurn.
I'm confident that it will be an excellent utility.
I guess we should just hang up LCam Turn.
It's like "beating the dead horse."
Thanks Chip,
RC
-
Saumur,
On the Turn home screen, click Tool Table. Or on the Run screen hit Tool Adjust.
Then you will see the Tool Table Editor. There, you can select the tools and set the parameters.
But there is a problem with Tool Nose Radius Compensation, which is what you will need to cut your part accurately.
It is one of the functions that was never finalized.
Hopefully, it will be OK in the new LazyTurn when it is done.
It's function is explained well in the "Using Mach3 Turn" manual.
If this does not answer you question, please reply.
RC
-
so all i have to do is set the tool, put in the g-code to use tool number 1 and it will work with the setting i've put in that tool automatically?
-
Yes, I believe that's the way it is intended to work.
The tool descriptions should be the same for each tool that you set-up in the Mach3 tool table and in the Lcam tool table.
But.......It may not work correctly due to the problems with the Lcam Turn software bugs.
If your finished tolerances are not critical, just define a 2mm rad. button tool in LCam, (save then select), and generate the code.
I think that would just offset your profile 2mm with no compensation.
That may be close enough ? ? ?
-
Overload,
the person that is doing the g-code for me at the moment set the tool in the CAM like it should be.
The problem is that if i set the tool (in layers right?) the g-code i create will be always the same no matter what tool radius i put.
I would like to know why this happen....
-
That may possibly be one of the "Bugs".
You have to remove the original profile before generating the code, or it will generate it as a toolpath.
You probably knew that,
RC
-
What does that means?
I'm sorry but i'm a noob...
-
First... you select a chain,(your profile) to offset, then you generate the toolpath.
When you are satisfied with the toolpath, you need to highlight the original chain and remove it before you generate the code or LCam will use the profile as a toolpath too.
Then you can post the code to Mach3.
RC

Solved my problem thanks
-
Man i really owe you know, thanks a lot.
Anyway i got 2 more things to ask you please:
When i create the g-code it comes with some g0 fast movements that are useless, do you know how i can quit these g0?
In lazycam for lathe you can't work in diameter mode right?
Thanks again
-
Once the Gcode in in Mach, click "Edit" on the auto screen and modify the code as you like. You can put ( and ) at ends of a line of code and Mach will ignore it. When you close the window, it will prompt you to save changes. Click yes and it loads back into Mach.
LCam is RADIUS mode ONLY.
RC
-
Isn't there a way to create the code with some standars line always instead of edit it everytime?
thanks
-
There very well may be, but I am new to this and do not know. That's why I just edit.

Hi, Saumur
LazyCam is still a Bata Program, The post's still need some work, Even higher priced Cam packages require some tuning to get the post's the way you may want them.
There are many option's with G-code, Hears a link to Mach3 Turn http://www.machsupport.com/documentation/Using3Turn.pdf
I don't understand your comment on G00 moves as use-less, These are rapid moves.
If thy are causing problems like lousing position when you use them, Your velocity setting are not set-up properly.
Read up on G-code some, You need to understand how to use it.
Thanks, Chip
-
Thanks for the answers.
Anyway regarding the g0, when i post the code it come with 2 g0 movement of 0.0002 mm; as you can understand it's completely useless a g0 movement of 0.0002 mm
-
anyone knows if you create a g-code that starts the drawing from the right instead of left?
thanks
-
Hi, Saumur
Move the 0,0 marker to the right side, Click on it hold down and move it to the right side.
Thanks, Chip
-
Thanks Chip,
one last thing; my drawing is divided in 4 chains.Is there a way to combine them all and have only 1 chain?
I tried with optimize and sometimes it combine 2 chains into 1 but after that i can't combine others 2.
-
Hi, Saumur
Your lines probillyhave a small gap, Try setting the Setup, Load Options, Connection Line Tol. to .01, then re-load your file.
Thanks, Chip
-
THANK MAN!!!!
-
Thanks for the help guys thanks to you i learnt many things.
If it's possible to do this i'll be able to do all the things i need: is it possible to create a g0 movement from lazycam so that when the piece is done the tool move away from it?
More like if with lazycam you can create a g0 movement you want or you must do it with your cad?
Thanks
-
anyone knows?
-
Saumur,
I just edit the tap file at the end.
G0 Z? (to make sure Z is up and will clear everything)
G0 X? Y? (to where ever you want)
M30
-
Thanks for the answer,
yes that's a possibility i just wanted to know if you can create them in LC.
