Title: Some LC questions
Post by: Kristin D on April 23, 2008, 08:11:06 PM

I see there is a sticky note about needing microsoft .net, it seems this installed with my recent download of Mach3 demo, do I still need to update this? I followed the directions someone had listed for getting a DXF to LC to Turn and don't see any Gcode loaded and can't find any that had just been generated in the Mach directories. I am a complete novice at CNC so bear with me if I don't make a lot of sense with my questions since I do not know the term's quite yet to describe what is going on or wrong.

Now what would be nice is if someone could post a simple DXF say a shaft with 2 or three diameters turned, the coresponding gcode so I can try to duplicate the result. I have been trying this with solid edge to make the dxf file, perhaps that is the problem.

Thanks,

Kristin

Hi, Kristin

Like this.

Hope this helps, Chip

Chip,

I tried to run the TAP file and it hangs for a long, long time on line 3 trying to travel several thousand inches, tried to add a decimal point after 2 digits and got an error. Help.

Chip, Kristin is right.....something is amiss.

Hi, Kristin

Well that's what I get for not running the code before sending it, Probability close to the national debt.

This is closer to what it should be.

Chip,

Thanks for the corrected code, I finally got my three axis control board all sorted out and was able to run it, now to tackle the DXF file and see if I can covert to G-code. Now I have three working channels I can actually see what I can do and get to work on the mechanical end of things. This has turned into some sort of project, at least now it looks like I only have to fight the software from here on.

Kristin,
I posted some info back in Feb. under the topic of "LAZYCAM CODE-FOR A NEWBIE". It should shorten your lathe learning curve.
Also quickly looked at your DXF and noticed that the lines were not connected. One thing I always do is make sure that the beginning
and end of lines are closed / start and stop at the same points. You can set tolerance diferrently to take care of it but eliminating CAD
generated mistakes are worthwhile before an export. I'm a newcomer to MACH and currently interested more in the lathe end of things.
Happy turning!
RICH

Rich,

I just searched and found the post, I had already downloaded it, someone else had pointed me there a few weeks ago. The DXF file was not mine it was an example someone else posted, going to have to take a look now and see where the lines are not connected. I was able to draw a similar dxf with Solid Edge 2D that worked for converting, but darned if anything would load to the Mach lathe program, as a matter of fact I am not sure now if it even saved the code file. Something else came up and I have not had a chance to go work with it since.

Thanks,

Kristin

Hi, Rich, Kristin

In Setup you can select the connection line tolerance, If your set at .001 it may not consider the lines as connected try .01 and see if that helps,

Change it then load your Dxf, LC Lathe is in rework so there may be relief soon.

Thanks, Chip

Thanks Chip,

I just checked back and found your post, when might the "new" version become avalable?
