Centurion 6 Engraving strange with CAM program
Hi all,
I'm using a Centurion 6 controller and create the programs with BobCAD Cam. Programs work very well. But when I try and do engraving something odd happens. Whenever I'm doing a round figure, like an "O" or an "8", it constantly moves Z up and down. I output the code as arc segments instead of line segments simply because the program size is much smaller. So an "O" has 4 arc segments. The z-axis comes down and does one segment, then retracts z to clearance point, then comes right back down and does another segment, repeat, repeat. It looks like a sewing machine. There is nothing in the code anywhere telling Z to move up and down. I see one z move when it starts a letter, and a z move up when it finishes the letter. Is there a setting in the controller to stop this strange behavior? Program is in pure g-code, not the Milltronics weird parameter type code. Any help would be appreciated.

Here it is. A bit long, sorryOriginally Posted by ZZZZ
Also below the TEST code I have posted just the code for engraving a capital O. I think i'm seeing something there but will wait to see what you guys say. I'd rather have a different set of eyes on it than me
((below is code for TEST O))

On my software, the tool rapids to the approx 0 degree point on the letter O, feeds down in Z, feeds around the letter, rapids up and over to the Letter T, feeds down, etc. Other than skipping the center bar on the E, this looks fine to me.
I don't see any arcs at all, only lines.
Yeah, and that's what I noticed. No arcs. I had just done an update to the CAM software so I need to look at it some more. Have the old version saved so I can compare. Something may have changed in the software now that they no longer are doing arcs because I didn't see any unusual z moves either. That figures.. On the day I finally decide to ask a question about it. But I know what I saw before. Unexplained Z retracts, was driving me crazy. Thought it was a parameter in the Centurion somewhere. But thank you very much for your time into looking at it, hopefully it's fixed now
You will want to compare the code from the two versions of your CAM software to see what the differences are. Remember that the control only does what it is told.
