And the nut fit the first time!

Glad you got the code working.

I have been fiddling around with some of these routines from this lathe section of the forum.

I added in the "tolerance" parameter for the metric threading macro.

I have also sorted out the order of the #vars as apparently with NGCGUI they need to be #1 #2 #3....#15 in numerical sequence. I notice that the "tolerance" in the original macros was out of sequence, so I've just resequenced both macros.

I've also added a bit of a check to find out what the current units you machine is set to at the start of running the macro and reset it back to those units at the end of the macro. The problem is not all of us use imperial machines .....

Check that the macros work for you and there are no errors as I've NOT run these on my machine yet, I was just doing a bit of a clean and tidy up on the general macros I downloaded to make them a bit more universal.

I also added a tool change in the sequence and coolant and also the rpm which was fixed as part of the macro.

Hopefully someone finds it of use / helpful.

you will need to rename them from txt to ngc

Threading routine now fortified with ACME threads!!

I had an ACME threading project, and realized my threading routine would require a bit of revision to cut them. The parameters for ACME are a bit different than regular threading.  I made some modifications, and this new version will now cut ACME threads.

I did not modify the metric version of this code. Metric threads are Trapezoidal, which are similar but not the same as ACME. It would require a bit of tweaking of the ACME code, and I don't currently plan any work on this.

I hadn't looked at these posts in a while, and saw that robertspark made some revisions to my original code. I have not looked at those, so this new version does not include them. I'll try to take a look at them in the future to blend them in.

Finally got a chance to revise the code. This version adds tool number, spindle speed, and coolant to the previous version with Acme threading..

Enjoy.

Nice work/contrib. Useful.

If you decide to take it a level up one of those day, shout out and I'll put up the metric Tol & Grades EQs pub domain for internal and external threads. Not utterly complex to do imperial too, if required.
