Show"N"Tell ( What you have made with your CNC machine.) / Not going till the end of line

« on: December 11, 2013, 05:27:07 AM »

Hello,

As always some problems and don't understand why so simple things can't be done easy way.

The spindle gets into to the material and goes straight till the end of the line, but before the end of line the spindle goes up. The feed rate is 2600mm/min, also tried with slower ~1300mm/min, but the result is the same. So after first cut i have to rotate the material 180 degree and cut again to get the same results in both ends. 

I have attached my .dxf and .nc files (nc was written with Aspire)

Thank you, i will try to reduce the feed rate. But it's not very big, 3000mm/min.

Attaching .nc file and toolpath pictures, "back ploted" is from madcam support, they told me that everything is ok. I need to check problems in controler.

Also attaching .dxf file.

As you can see all coners are not rounded, but somehow machine cut one corner with radius another one without

Ok here we go again:

First i have writed to MadCam support, because i was thinking it's madcam postprocesor problems, but they looked and told me it's mach3 problems.

When i am cutting, somehow cnc machine cut one corner is with radius, another one is ok. But it should be both not rounded !

Attached pictures.

I don't understand anything, today i downloaded .nc file witch i attached in first post and now it is working perfect !?!? I didn't changed anything, didn't installed or uninstalled any programs and didn't change any settings. Now the green dot go by blue path exactly.

Yesterday windows was updating 3 updates before shutdown. Can it be a reason ?

Thank you for your help ! I will try to learn how to write .nc files for 3d models.

So the same will be with MadCam ? And all other cam software ?

Yes it working perfect, because all corners are orange color. And green dots are going exactly by blue line.
Also it is working for me if i write .nc codes with SheetCam, or write .nc code in Edgecam from 2D lines.

But it is not working if i write .nc code from 3d models creating the same pocketing or roughing option. All corners are blue color from 3d models.

I don't understand what is the problem.

Sorry for spamming but i want to describe this situation as much as possible. If i import to Edgecam 2d .dxf file and write .nc code, mach3 works good, but if i make the same with 3d model, i get the same problems, that green dots are not going exactly by blue path. I don't know is it mach3 problems or cam software, but i don't think that all 3 different software can make the same bad results.

Also made .nc file in sheetcam from this attached .dxf file. As you see it works fine in mach3 from 2d lines. But then i try to use 3d models from other software like Edgecam, MadCam, RhinoCam, i have the same problems above.
