Hello,
I have a MicroMark 7x14, retrofitted to CNC. I finally got around to getting an index pulse so I now have spindle speed to do threading. I am using an opto interrupter, with a disc cut about 45deg to create the pulse.
I have been using both the simple and complex threading wizard, but it goes diagonally starting at the correct depth then moving away.
It appears to be making the correct step in each time, but then makes the triangle away from the piece in stead of making a thread.
I took a video of the screen to show what it is doing. And the machine path matches the new white line it is drawing in the video.
http://www.youtube.com/watch?v=etNtx_wk9D0I have the taper set to 0 deg, and in feed is at 29.5 degrees.
I have tried it in both radius and diameter mode same results.
Why is it doing this?
It also doesn't appear to be starting at the same part of the thread, like using a thread dial gauge and starting on a different number every time. Any Ideas?
Also I don't have the spindle control done yet. So why doesn't it change the feed in proportion to the spindle speed? If I speed it up or slow it down, the feed remains constant. I am assuming that I have something set wrong, any ideas?
Any ideas or suggestions are greatly appreciated.
Thank you for your time,
TJ
