G-code assistance

[JimDawson]

Here is one problem, the arcs in the ''S'' are not correct. But the ''J'' and ''L'' look good

 

[jlsmithseven]

yeah i just downloaded a free program and i saw the same thing. it was fine up until my second arc movement, which i kind of figured was off. let me try to fix it on my own first.

 

[jlsmithseven]

i EDITED my code up there. i used that free software and it let me see what i was doing wrong. learned a lot through you and this software. thank you so much!

 

[JimDawson]

For testing I'm using a combination of CamBam, Mach3, and my own CNC software.

The screenshot is from CamBam, I just imported the nc file

Mach3 just throws errors.

My CNC software will digest any post processor format, but still doesn't display the toolpath correctly. I need to look at a couple of settings. The recompiled G-code looked OK.

 

[JimDawson]

Please post your new code

EDIT:

I found my problem, your post pointed out a bug in my software. It doesn't like the leading ''0'' in the G commands. ''G01'' it doesn't like, but it does like ''G1''. I need to fix that, it should digest either format.

This all started what's left of my mind going. Somewhere......
One night I came to work, was told that 'tomorrow was open house' they wanted something like a key fob to pass out. The gave me a D print of the Company logo and a stack of 2 by 3 1/2 Lucite pieces. It took the whole shift, but when I left (with instructions) anyone could put a blank piece "right there' in the vice and push 'that' button and it would turn out a company logo on the Lucite. This must have been 30 years ago.
I found one of the pieces in an old tool box. The originals had a 3/16 hole in a lower corner for a ball chain.



This is about 4X, the small lines are .020 wide.
The company produces compressors for the natural gas industry, up to about 9,000 hp. The logo is a connecting rod. The name came from a motorcycle the owner once owned.

That's funny because we just gave away connecting rod key chains at a stand we had for our college. Ironic.
