For some reason I thought that you were using a parallel port.

It isn't actually possible to interfere with the index pulse with a Mesa card config.

(Well, it is just about possible, by taking the signal in to HAL and then out again back to the mesa board)

Sorry for leading you astray.

No biggie. I got a few days waiting for a same size gear and there is just enough room and belt to shove it in there.

It just forced me to learn a little more ;-)

Got threading good enough to do what I need. Thank you everyone for the help getting here.

Moving off the lathe to the Mill. I am not finding out how to slow down the jog speed of the Z axis going up and down. The jog speed slider in the GUI only changes X and Y jog speed.

Trying to find out how to connect the Z axis jog speed to the same jog slider speed that changes X and Y.

Any ideas?

Well, _that's_ not expected behaviour.

Can we see your HAL and INI to try to get to the bottom of that?

Nice.

Now is about the time you are likely to find that threads (to a standard) are harder than they appear. ISO metric and SAE threads have a significant flat on the threads, taking them p/6 smaller than nominal. Whitworth and ISO pipe threads have a rounding that does the same, but is harder to machine.
If you are trying to fit to an existing part, don't keep reducing the diameter of a pointed thread until it fits. If you do then the root and thread thickness will be under. Draw your thread and touch-off the tool to get the major and minor diameters right with the actual tool.

ok thank you for the heads up and info. so far I was cutting my mess to my own bad mess of threads and not matching other than initially using a die as a sanity/learning check to first fix my numbers and then figure out how much slop I needed to add to get the die to roll ok.
