Cnc lathe crashing with conversational programming (Resolved)

[benscale160]

I don't know what is going on with conversational programming on my emco 6pcnc lathe. I just started messing around with the profile function of intercon. Set up a roughing profile cleanout with a finish pass. It goes though the motions of the rough pass just fine. It goes back to tool check for the finish pass and then beyond and crashing into the z hard stop. Can't figure it out. I watched the machine in the machine coordinates. Best I can figure somehow the controller is resetting home. Don't think is it missing steps. I'm using teknic servos. I'm using tool corner radius comp with g41. G28 is set up x.1 and z.1 from machine home and hard stops. Is there perhaps a bug in the post? Is there a way I can view the entire g code instead of the abbriviatred version that intercon displays.

Turning. Boring and grooving all work when going back to tool check. I also recently upgraded to cnc pro.

Any help is appreciated,

Thanks

You are losing steps, or there is mechanical slippage in the drive train.

Press F6/Edit to view the G code file.

G28 is set up x.1 and z.1

That would be unusual, since machine home on a lathe would typically be at the positive limits. Trying to move to the positive side of machine home would, therefore, be a problem. However, since you did not include a report, we can't really tell how you are homing your machine or what travel limits you have set.

My apologies, it isset up X -.1, Y -.1 for g28

And no, I'm not loosing steps or mechanical problem, it's something in the code. I Generated similar code using the turn function and there were no issues changing tools or crashing. Made 10 parts no issues.

It appears things go haywire right after the rough pass on the profile. Let me know what I need to post in order to demonstrate this.

Need a current report and the Intercon program that is causing the problem.

Ben,
Please post what Centroid support is asking for. Current report, the intercon files, and G code.
OR if your problem is solved, please let us know what you found. It benefits everyone.

Well, I found the issue. I have the rough passes set for f/m with a value of 5.000 and guess what lol, the finish passes set for f/r with a value of 2.000. No wonder it crashed. I changed it to f/m and all is good. Rookie mistake. It's amazing how machines do exactly what you tell them to do.

thanks for posting the resolution.

thanks for posting the resolution.

Bahahaha,
Resolution.... Get it. (Sorry)

Totally bit me the first time I used my lathe too. Kept getting position errors. (Turns out my machine didn't like trying to go 20 inches per rev)
