I was playing around with my path pilot today. Thread milled a hole and the threads were left hand. I don't see anywhere to change to right handed threads.
I don't have it, but is there a top-bottom vs bottom-right option? Typically a right handed thread is milled bottom of hole to top.Quote:

Just change G02 to G03, or vise-versa.
I had the same problem the first time I cut an inside thread. I must have reprogrammed that thread a dozen times before it hit me like someone hit me with a baseball bat.
START AT THE BOTTOM AND THREAD UP.
Installed v 1.6 the threading appears to work normally. I did learn that the machine needs to be out of e-stop to choose internal or external threads in the conversational tab. I also noticed that the z dro does not change while the machine is running (the real z is actually moving normally).
I did thread milling on PP v1.6 the other day and starting at the top and going down worked just fine.
Whether you go top-down or bottom-up is a function of both whether you're cutting LH or RH threads, and whether you're climb or conventional milling.Quote:

When thread-milling, climb milling is strongly preferred.

OR, climb cutting or conventional cutting. To climb cut a right hand internal thread, start at the bottom and thread clockwise up. If you go top down, you'll be conventional cutting. Not really cutting, just pushing material out of the way.Quote:

Did you not bother to actually read what I wrote before responding? And conventional milling is hardly "just pushing material out of the way". It cuts, and makes chips, just like climb milling, the only difference being the chip is thicker at the end of the cut than at the beginning, while climb milling is exactly the opposite.Quote:

All of the conversational programs appear to climb mill by default, without the option to conventional mill.
