For testing, don't take to deep a cut. Many light cuts. Also start the threading a bit ahead of the end of the part. I havent had much change to get into the shop lately, but I did a new model and test today. I've included the cnc file, clean report and a picture of the thread. I'm using a carbide ...

You aren't going to hurt the stepper! Have you tried to do a thread yet? Get a piece of PVC or Delrin and try it. Post pictures of your results. You seem to have a lot of lash in Z though that should be taken up ahead of the thread. What kind of stepper drivers do you have? What is the motor voltag...

It's mainly to show that it appears smooth yet hopefuly you can hear the ...

Updated report as of today (Since parameter changes)

For threading take the RPM times the pitch of the thread that will give you the inches per minute the cross slide will be moving. PR...

Not quite sure what you need for the intercon program? I'm assuming what I have attached for that one is not what you need? You didn't post the intercon file generated when you used CNC12 to create a threading cycle. Marty The file "conversational thread test v1.cnc" is the one generated ...
