thanks Hood

that is a lot of good numbers, makes a person think about going shopping.

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

This is the motor,  http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=250276403349&ssPageName=STRK:MEWN:IT&ih=015
it is 12.5Kw, 83Nm  (735 lbs in ) continuous torque  152.5Nm  (1350 Lbs in) peak.

 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

Yes you may

Hood

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.

Hood

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.
