Need Help!- Can't do radius'

[jeremyrockjock]

I make my drawings in AutoCad saved as a DXF then open it with LazyCam and do come cleanup and settings and then send it to Mach3. It works fine with any straight line but when I try any sort of round shapes Mach gives a message stating the start radius is different from the end radius. Is this a LazyCam issue or is Mach3?

Change the IJ mode in Mach3.

[jeremyrockjock]

What is IJ mode? I am new to mach and CNC.

[ger21]

Go to general config and find it and change it. It specifies the location of the center of the arc.

[jeremyrockjock]

Will do. Thanks Gerry

After resetting my profile I am having this problem again. I don't remember how I fixed it by there is no IJ mode under general config.

[ger21]

Here.

I am blind. I stared at that page until I was so mad. Thanks again Gerry.

[jeremyrockjock]

I changed it but it still won't work. Anything else to look for? Should I post a screen shot?

[jeremyrockjock]

I tried creating a new profile again. reset all my parameters and now its even worse. Its creating crazy huge arcs. Here are some shots.


General config which is too large for my 15 inch monitor



Lazy Cam shot of what the part shape is supposed to look like. Plus is too large to fit my monitor.




Mach 3 shot of what the shape is coming out as.

Can you post the g-code? And you should try setting the resolution to 1024x768.

I'm also having the same problem. Two days ago I downloaded a Lazycam update from Artsoft. Loaded onto my computer and now when I try and post new G-Code, I get an error from MACH 3. Error reads " Radius to end of arc differs from radius to start line 9".

My original TAP files still run fine. The new ones (from the updated Lazycam) are giving me trouble.

Any ideas of what I have done wrong or should do?
