:)
The lathe itself cost me £300 ($600 approx) but there were no servo drives with it (my friend got them) Think I have probably spent in the region of £1000 ($2000) on the lathe including the original purchase. I have now just got a BIG servo motor and drive that I hope to put on the spindle so that will add another  £500 but it will be worth it if it works :)

Peter
 Have attached a file for a similar stub shaft to the one I did earlier except just quite a bit smaller. I have made it with a DOC of 1mm for the roughing which should be fine for your lathe. The speeds and feeds should also be fine for you if you are using carbide, I have noted in the code the tools that I used. I ran the code on the lathe here with 38mm dia EN24 and have taken a pic with the phone but will have to wait until I get home to download. It probably wont be worth seeing as the phone camera is not that great :( Oh and the thread is M10

Here is a blurry pic taken with the phone but at least it shows the code works.

Hood, may I ask what version of Mach 3 Turn are you running?

Thanks,
Dave

Sorry couldnt resist, at the moment I am using 3.042.005, I would however advise against using it unless you feel like being a guinea pig, it has a lot of changes in the way it works and there may well still be some undesireable bugs.

Funny stuff there, chief -  ;)

What would you recommend being the most stable yet up to date version of Mach 3 Turn?

Thanks,
Dave

I dont know really, dont think there have been any Turn specific changes since way back (1.74 I think) so I suppose the lockdown will be fine. The latest ones once finished will make a big difference in the way VB works within Mach so it will be an advantage to use them but only after all the bugs have been ironed out.
