General Mach Discussion / choppy circles?

« on: December 10, 2007, 05:01:13 PM »

bridgeport with ball screws & servos.

cutting outside of circle and getting small line segments rather than a smooth circle. have cut fast & slow. 

The x&y were SO close in the tuning that I made them identical thinking that was the problem. NOPE.

The computer is bare/clean as per artsoft instructions.

You can watch the screws go & stop, go and stop... any ideas?

Brian, if after feedhold, you jog the table, what would the procedure be to continue from where you had hit the feedhold?

Hey Jerry, try this. Load some code and start cutting air. Act like it is going to hit a clamp and push your feedhold and jog the machine away. Now, press cycle start. Did a prep. move box pop up? If so, click OK, yes, apply, (can't rememer exact wording). It should now go back to posotion it was at and start running from there.

Brett, it didn't ask anything...just continued machining from where I jogged to...

LazyCam (Beta) / Re: Arc import prob in Lazy cam

Brian, with all due respect...I have gone back nearly a years worth of posting only to realize that this problem has existed for at least that time based on threads you've answered.  As someone new to cnc, the stuff I'm trying to import is baby talk to most all here. I've tried as many ways to get a simple file into lazycam as some of the people posting.  I recently purchased Mach 3 and would gladly fork over the lazycam fee, if only I could get a simple circle to import in just 1 file format.  As it looks now I need to find a lazycam replacement??

G-Code, CAD, and CAM discussions / Newbie simple drawing HELP!

« on: November 23, 2007, 12:22:01 PM »

Attached is a scan of a gasket I thought it would be a great 1st cut.

Thing is, I can't draw! I've spent an incredible amount of time (mostly in corel) trying to manually and auto trace (several programs) this simple part with no great success!

Can someone please draw this and tell me how the best way of doing it is? I'm beginning to think cnc is not for me!

The holes are 13/64.

TIA!
